86 common faults:

1, the air output is small and the cooling effect is poor?

There are many reasons:

A, the external environment temperature is high, there are many indoor personnel, and the air conditioner is working at full load.

B, the power supply voltage is too low, which makes it difficult to start the air conditioner, and then stops or the fuse is blown. Users are advised to install a power regulator.

C, open in a room with a strong cold block, the temperature can't drop, and the air outlet is not big. This is because there is too much dust in the air filter, so clean the filter.

D. The thermostat is not properly adjusted.

E. Bad installation position of air conditioner will lead to uneven indoor temperature or poor cooling effect.

2. Is the inverter air conditioner stopped normally?

When users use air conditioners, the environmental insulation is very good, and the indoor temperature is very close to the set temperature. At this time, the inverter air conditioner will stop. Because even if the inverter air conditioner runs at the lowest frequency, it will produce some cold energy, but there is no energy loss indoors at this time. According to the law of conservation of energy, the air conditioner will stop running at this time.

3. The user consults that the air conditioner is set to 17 degrees, but when the air conditioner drops to 25 degrees, it will not drop again. Is the air conditioning and refrigeration abnormal?

The user sets the temperature to 17 degrees, and the user's air conditioning environment always has cold and hot exchange with the outside world. At the beginning of refrigeration, the room temperature can drop rapidly because of the small temperature difference between indoor and outdoor, but when it drops to a certain temperature and the cooling capacity generated by air conditioner is just equal to the energy loss between indoor and outdoor, the room temperature will not drop again. At this time, the cold generated by air conditioning refrigeration is only enough to maintain the energy loss of the room. Users need to improve the cooling effect, and it is best to suggest that users improve the sealing performance of the room to avoid excessive energy loss indoors and outdoors.

4. The user responded that it was used normally last year, but the regular voltage used this year is insufficient. Is the air conditioner easy to age after one year's use?

Ask the user whether the power supply voltage of the air conditioner is abnormal. If it is abnormal, it can be explained to users that the power supply voltage of the community where users live has not changed, but more and more users use air conditioners, and the power supply will be abnormal. This is not the case that air conditioners will age after one year of use.

5. Why doesn't the remote control display?

A, check whether the battery is installed correctly and whether there is electricity.

B, check whether there is poor contact, if so, ask the user to adjust the contact piece.

If not, please go to our outlets for maintenance.

6. Air conditioner leakage (indoor unit)

Cause analysis:

The drain pipe is blocked, detached or damaged;

B installation is not level;

C. After the collision, the water tray shifts;

D the outdoor water receiving container has been filled with water, and the outlet pipe is blocked by water (actually, the outdoor atmospheric pressure will suppress the water in the pipe). Just pour out the water.

E when the indoor air humidity is high, there is a layer of water droplets on the surface of the air outlet frame, swinging blades or connecting pipes of the indoor unit, which is a normal phenomenon.

Solution:No. 1, No.2 and No.3 need on-site maintenance service, and No.4 and No.5 need explanation.

7. How to choose the correct air conditioner model and the corresponding installation location?

When selecting air conditioners, users should fully consider the size of the room area, the structure, orientation, top floor, walls and sealing conditions of the room. Whether the outdoor unit is installed to avoid sunlight, dust and smooth exhaust. Generally speaking, the number of W required for cooling and heating in different environments is: ordinary room: 150- 170(W/ m2), living room and small office: 160-200 (W/ m2), and dining room: 220-350(W/ m2).

8. The whole machine does not respond when it is electrified, and it does not start.

Please check whether there is electricity in the socket first (try to plug in simple devices such as fans and lights). If not, please check the power supply of your home; If there is electricity in the socket and the power cord of the air conditioner is not damaged, there is something wrong with the internal power circuit of the air conditioner, so you need to contact the local outlet for home repair.

9. The user's voltage is low and the air conditioner cannot be started, but other brands of air conditioners can work normally under the same conditions. How to explain it to users?

If the voltage is too high or too low, and the air conditioner is used under this condition for a long time, it is likely to damage the compressor and other electrical components. From the user's point of view, Midea Company has a slightly stricter voltage requirement in order to protect the electrical components in the air conditioner. Therefore, the air conditioner should work normally, and in order to reduce the damage of electrical components, it is recommended not to use the air conditioner frequently when the voltage is too high or too low. It is best to buy a regulated power supply, and its power should be 3-8 times the rated power of the air conditioner.

10, the air conditioner is normal, and the room temperature can't drop. How to solve it?

Whether the room temperature can be lowered is not only related to the refrigeration quality of air conditioning, but also depends on the insulation quality, sealing, window area, orientation, floor position, number of doors opened, number of people, other electrical appliances and heat sources. In addition, the temperature difference between the inlet and the outlet can be measured. If the temperature difference is within the range of 10- 13 degrees, there is nothing wrong with the air conditioner. If users don't accept this explanation, they can suggest that users install air conditioners in smaller rooms, or make up the difference for larger air conditioners.

1 1. Why are no cabinets above 2P equipped with power plugs?

Because the instantaneous current of a cabinet with 2P or above is very high when it is started, which is 2-3 times of the working current, the maximum current that the general air-conditioning plug can bear is about 15A, but the general plug can't bear such a high current when it is started, which will lead to the burning of the power plug and even fire. In order to avoid such accidents, the National Security Bureau does not allow air conditioner manufacturers to be equipped with power plugs, and must use air switches or knives.

12. After the installation of the air conditioner, due to the long power supply distance of the user, the user's request for wiring the power cord was rejected by the installer, resulting in user dissatisfaction.

The power supply line of cable drawing needs a professional electrician, and the installer is not a professional electrician. For your safety, please invite an electrician. After the power supply circuit is completed, it will give you a trial operation, so that you can use it with confidence.

13. Why is there water at the nut of the air conditioner? Is there any leakage of fluorine?

It's not fluorine leakage, please feel free to use it. It is not the cause of fluorine leakage in air conditioners, but a physical phenomenon. Because the temperature here is very low, it is similar to taking out a bottle of mineral water from the freezer. In hot air, it meets the condensed water of the steamer or adheres to the surface of the copper cover, and water will flow down the bottle wall in a short time.

14. Why is the air conditioner frequently turned on or off at noon or at night, or the external machine cannot be started?

This situation is generally caused by the unstable power supply of users. You can ask the user about the voltage in the area where you live, pay more attention to whether there are such complaints from users in this place, and explain to users that these two periods are peak hours of electricity consumption, resulting in insufficient electricity. Air conditioning is a high-power electrical appliance, which is difficult to start. Users are advised to buy voltage regulators.

15, the air conditioner is not turned on, and the running lights will flash. Is there something wrong with the air conditioner?

No, this is a standby display state, which can be turned on at any time. There is also a reminder function, that is, many users forget to unplug the air conditioner for a long time, and the lights will flash to remind users.

16, the wind speed of the internal machine is fast and slow, and the wind is strong. Why?

Ask the user first if the filter has not been cleaned for a long time. If not, explain to the user how to clean it, because the dirty filter will affect the intake air, resulting in uneven wind speed. If it doesn't work after cleaning, you need to send maintenance personnel to check it at home.

17, press the remote control and there is no response. What should I do?

First know whether the air conditioner is turned on (for example, whether the running light is on). If the running light doesn't light up, first check whether the next socket is electrified, or change to a mobile socket to try not to supply air indoors. If the running light is on, it is recommended to replace the battery with a new one; If not, send maintenance personnel to your door.

18. Why do newly installed machines make noise when exposed to wind?

Because the newly installed pendulum shaft is too wrinkled just after use, it needs a period of running-in, so you can drop some lubricating oil on it.

19. What sound does the indoor unit have when the air conditioner is normal?

When the air conditioner works normally, there are the following kinds of sounds: a, the sound of air conditioner running, which can be improved by adjusting the corresponding wind speed; B, the "crack" of the thermal barrier of air-conditioning plastic parts due to cold shrinkage cannot be completely avoided, and can only be improved by adjusting the tightness or position of the shell; C, the sound of refrigerant rapidly vaporizing and liquefying in the pipeline.

20. Is the air conditioner always turned off when the timer function is set?

Some new remote controls only have a timer button to set the timer function. In operation, because the first function is' timing on', the delay time of transmitting signal is only 2 seconds, so it is very likely that the' timing on' signal is transmitted without setting the timing function, resulting in misoperation. At this time, you can put one hand in the transmitting position of the remote control, set the corresponding function, then move the hand away, and then transmit the signal.

2 1. Why does the air conditioner smell when it is just turned on?

The air conditioner itself is generally odorless, which may be caused by the following reasons when it is turned on:

Indoor odor: when the air is not circulating, the odor is unpleasant. When the air conditioner is running, the odor is concentrated in the narrow air outlet, which strengthens the odor that is usually undetectable. At this time, the indoor environment can be improved.

22. The display temperature of the portable air conditioner remote controller does not match the display temperature of the air conditioner.

The temperature displayed on the air conditioner is the outlet temperature, and the actual indoor temperature is displayed on the remote controller.

23. There is noise in the indoor unit.

A. there are sundries in the machine. B. the mounting plate is not hung correctly. C. there is friction between the wind wheel and the motor cover.

24. Jump and stop after the air conditioner is started.

A. voltage problem. B. main control panel of internal machine. C. external machine capacitance problem. D. the liquid crystal display of the switch board is incomplete. E. Thermal protection of external machines (such as long sunshine time and dirty condenser).

25. Why does the newly installed air conditioner drip, but not the one bought the year before last?

The newly installed machine drips water because:

A. It may be caused by water leakage in the machine-the water in the machine is introduced into the water pipe through the sink and flows outside.

B. Condensed water is generated at the copper valve of the external machine.

The air conditioner bought the year before last has been used for a long time, and the copper valve is covered with dust. Putty plays the role of heat insulation, so it doesn't drip.

26. Why is the red light on when the air conditioner is running and pressing any key doesn't work?

When the air conditioner is running, the required voltage is 195V-245V. If the red light is on, the voltage may be unstable. Unplug the plug for 3 minutes, let the air conditioner reset, and then plug it in. If it is unstable for a long time, it is recommended that users be equipped with a voltage regulator.

27. Why does the air conditioner sound "card, card" after it is turned off?

This phenomenon exists not only after shutdown, but also during operation, which is mainly caused by thermal expansion and cold contraction of plastic parts.

28. Why do hanging wind guide blades sometimes drip?

In the case of high air humidity, if the temperature during refrigeration is low and in a low wind state, condensed water will be formed at the air guide blades, which can be eliminated by increasing the refrigeration temperature and setting it to a high wind state.

29. Why do the running lights sometimes flash and sometimes don't flash after the air conditioner is turned off?

This is related to the power situation detected by the air conditioner (such as power failure after shutdown or large power fluctuation), which belongs to the normal category.

30. Why not stop the inverter air conditioner when cooling?

The working principle of variable frequency air conditioner is as follows: when the indoor temperature setting is quite different, the air conditioner runs at high frequency (high power), and when the indoor temperature is close to the set temperature, the air conditioner runs at low frequency (low power). The indoor unit does not stop, and the outdoor unit will stop only when the indoor temperature is 2 degrees lower than the set temperature.

3 1. Why doesn't the air conditioner cool just after installation?

There are many possibilities: (1), fluorine leaks at the connecting pipe joint; (2) the connecting pipe is leaking; (3) Wrong wiring; (4) The fuse is blown; (5), compressor failure;

32. What is the reason for the water leakage in the air conditioner?

There are many possibilities: (1), the drain hole of the indoor water tray is blocked; (2) The drainage pipe is bent or flattened; (3) The drainage pipe is in the wrong direction; (4), the drain pipe joint part is lax;

33. What causes the air conditioner to switch on and off frequently?

There are many possibilities: (1), abnormal power supply voltage; (2) The outdoor unit has poor heat dissipation; (3) Excessive refrigerant;

34. The air conditioner emits "Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep Beep.

Plastics are caused by thermal expansion and cold contraction.

35. Users reported that the mouse entered the external machine and bit off the thread, especially in entertainment and dining places. Is the external machine poorly designed?

The external air conditioner is not well designed.

36. The air conditioner is plugged in, but it is not turned on. Why does the light flash?

One of them is designed like this or the voltage is too low.

37. How to choose the power cord after purchasing the air conditioner?

Air conditioners with operating current lower than 12A require φ2.5mm2 copper core wire to be connected with special wires, and the grounding wire is clear, which meets the relevant requirements of GB4706.32. Air conditioners with operating current higher than 12A require φ4mm2 copper core wire.

38. There is no condensed water flowing out of the external machine?

Condensed water flows out when the air conditioner cools. If it is ineffective, there is no water leakage in the indoor unit, which is usually caused by dry weather or indoor dryness.

39. The air conditioner starts and stops frequently and the cooling effect is not good.

The general reason is that the press starts frequently due to low voltage, so it is suggested to adjust the power supply; In another case, the set temperature is too high, so users are advised to set the temperature lower.

40. Why did the indoor unit stop sending hot air for about 10 minutes after the air conditioner was heated for a period of time? Is there a problem?

This is because the outdoor unit needs to be defrosted once when it is running 1 hour. It is a normal phenomenon and will not affect the use of air conditioners.

4 1. Why does the air conditioner smell when it is used for a long time?

The air conditioner itself will not produce odor. The filter screen and dust screen of general indoor units have not been cleaned for a long time; There is no simple cleaning and maintenance on the surface of indoor evaporator, which leads to mildew and deterioration, and blows out peculiar smell when starting operation.

42. Air conditioning is frequently started and stopped, and the cooling (heating) effect is poor.

This situation is generally due to low power supply voltage, insufficient capacity and unqualified wire diameter. During the peak period of electricity consumption, the compressor often starts frequently, which leads to the air conditioner not working normally. Just replace the power cord or apply for capacity expansion to solve the problem.

43. The air conditioner remote control fails at night and can only be controlled by manual switch.

The electromagnetic radiation of many electrical appliances will interfere with the remote control of air conditioners, and maintenance personnel can be called to the door for shielding and anti-interference treatment.

44. What is the reason why the air outlet of the indoor unit sprays water outwards?

If the water deflector is deformed, detached or loose, the condensed water will drip on the wind wheel and be thrown indoors by the wind wheel, which can be treated by adjusting or replacing the water deflector. On the other hand, untimely cleaning and maintenance will lead to dirty blockage, and condensed water will overflow from the auxiliary sink, drop on the wind wheel and spray water droplets from the air outlet. This fault can be solved by cleaning.

45. Wind that gives off an unpleasant smell

This is because the air conditioner sucks smoke and other odors back into the room and then sends them out, not a fault (the refrigerant leaks and has no smell).

46. The heat pump air conditioner does not start when it is cold.

Due to the limitation of use conditions, the heat pump air conditioner can't start normally when the outdoor temperature is lower than 0 degrees, so it is normal that it can't heat.

47. Turn on the air conditioner for a few minutes, and the three lights will flash together.

This is because there is a problem with the voltage in the user's home, which is caused by unstable voltage or low voltage, which is a normal phenomenon.

48, air conditioning water leakage phenomenon is more common, how to explain?

First of all, confirm whether the humidity in the room is very high, and can you see that there are copper pipes exposed at the connecting pipes? If so, it may be that the installer did not install it carefully enough, which led to the leakage of condensed water; If not, it is also possible that the insulation cotton is not thick enough, resulting in the leakage of condensed water. It is also possible that the installation of the indoor unit is too inclined, resulting in uneven water receiving tray and leakage of condensed water.

49. For out-of-warranty maintenance, how long is the warranty period of spare parts?

Spare parts are guaranteed for three months. If the same fault occurs again within three months, there is no charge.

50. The whole machine does not work after the air conditioner is turned on. The work light flashes at a frequency of 5Hz, but other lights do not. Is there anything wrong with this machine?

The fan speed is out of control.

5 1, the air conditioner starts cooling for 5 minutes and then jumps to heating.

The four-way valve does not work.

52. Machine noise is relatively high within half an hour after shutdown (user feedback).

The sound of liquid tapping is normal.

53. Why is there a pungent smell after turning it on?

A whether the user's room is newly renovated,

The hydrophilic aluminum foil of evaporator B is coated with antioxidant, which will disappear after continuous use for a period of time.

54. Why does the air conditioner often stop?

In most cases, the voltage is unstable. The normal operating voltage of the air conditioner should be198 ~ 242 V. Please equip the user with a voltage regulator.

55. Why are several lights of the air conditioner flashing at the same time?

Power on after power off. If it returns to normal, it is a voltage problem. If it can't return to normal, call the maintenance personnel to come to the door for testing.

56. How often does the air conditioner need to be fluoridated?

There is no fixed time to add fluoride to the air conditioner, mainly according to the refrigeration effect of the air conditioner and the pressure in the air conditioning system. If all these are normal, there is no need to add fluoride at all.

57. Why is a 1.5P air conditioner placed in a room of 6 square meters and stopped every 5 minutes?

Because the room of 6 square meters uses 1.5P air conditioner, the air conditioner has high power. Often the air conditioner just cools for a while, and the temperature near the temperature sensor reaches, so it is turned off frequently. In this case, an exhaust fan can be added to this room, which can not only solve the phenomenon of frequent shutdown of air conditioners, but also improve the cooling effect of air conditioners. Or adjust the position of the temperature sensing head.

58. Why does the inner shell of the air conditioner always ring?

It is because the inner casing expands with heat and contracts with cold, which often improves after a period of time.

59. Why doesn't the air conditioner work when the outdoor temperature is high?

The outdoor unit has poor heat dissipation, so it is recommended to clean the outdoor unit.

60. Why do some air conditioners of the same model have more displacement and some have less displacement?

A, air conditioning installation environment is different, such as different orientation. When the sun shines directly, part of the condensed water has evaporated, so there is less water.

B, the installation site humidity is different, and there is more water with high humidity.

C, different insulation effect, less water with insulation layer.

6 1. Why is the cooling effect still not good when the air conditioner is adjusted to 20 degrees?

A, air conditioning refrigeration effect is not determined by the set temperature (if the remote control is used correctly), the air outlet temperature is constant when the fixed frequency air conditioner works.

B. Whether the air conditioning environment is harsh (whether the voltage is normal, how the room is sealed, whether the outdoor unit has good heat dissipation, and whether there are too many people in the use place).

C. whether the air conditioning power matches the place of use.

D, the length of air conditioning operation time.

62. Why is the outdoor machine noisy?

A, whether the outdoor machine screws are loose, whether the wall is aging, whether the noise is the vibration of the window glass, whether the pipeline is bent flat, whether the dynamic balance of the outdoor machine blades is not good, whether there is a problem with the quality of the press, and so on.

B whether the axial flow fan, blades and compressor are equipped with sound insulation cotton.

Air duct design of the whole machine.

D, refrigerant flow of refrigeration system, pipeline design of refrigeration system, vibration of back net, etc.

63, why sometimes air conditioning refrigeration will blow out the fog? Is it normal?

When the indoor temperature and humidity are high, air conditioning and refrigeration will blow out fog. This is caused by the cooling of water vapor in the air. When the indoor temperature and humidity decrease, the fog will disappear. This is a normal phenomenon.

64. Why does the outdoor air conditioner leak water?

1), if it drips from the high and low pressure valves, it is normal.

2) Water leakage during heating and defrosting is normal.

If it is not the above two situations, it may be:

3), external machine connection pipe insulation is not in place, resulting in poor insulation and condensate.

4) Too much refrigerant in the system causes frost and water leakage in the liquid storage tank.

65. There is noise in the internal machine, not wind, not heat expansion and cold contraction, but buzzing sound, even when it is not working. Why?

The sound of the transformer.

66. A work indicator light sometimes flashes and sometimes doesn't. Is there something wrong with the air conditioner?

The air conditioner is normal and in standby state. You can unplug the plug when not in use, so this will not happen and will not affect the use.

67. The internal machine stops when the set temperature is not reached. Is it broken?

When the air conditioner is cooling or heating, there is a certain temperature difference from the set temperature, which is generally 1~2 degrees, which is normal.

68. The wind only swings upward, and the cold wind does not blow downward. Isn't it good to sway with the wind?

The problem of air conditioning design, cold air is heavier than hot air, and it will sink when circulating indoors, which is conducive to improving the refrigeration cycle of the room. When heated, the wind will swing upward, which is also the same reason.

69. Why does the air conditioner sound like running water when it is running?

This is due to the sound of refrigerant flowing in the refrigeration system, which is a normal phenomenon.

70. There is frost on the shutters of the air supply outlet.

If the air conditioner is operated under high humidity for a long time, water vapor may condense on the louver at the air outlet and drip down, which is not a fault.

7 1, the air supply is poor and the wind is not too cold.

This is because the air filter is not clean, so the filter should be checked and cleaned.

72. Blow out fog when cooling.

When the indoor temperature and humidity are high, the air conditioner will blow out fog when cooling, which is caused by the cooling of water vapor in the air. When the indoor temperature and temperature decrease, the fog will disappear.

73. Why can't it be restarted immediately after shutdown?

After the air conditioner is turned off, it can only run after 3 minutes, and the protection timer will automatically work to protect the main components of the air conditioner from damage.

74. If the air conditioner has been running well, it can't be started after a sudden power outage or other reasons lead to a crash?

You can ask the user to remove the power plug (turn off the air switch) and plug it in. If the air conditioner can be started, it is usually an electrically controlled zero failure.

75. Why is there no problem with air conditioning and refrigeration? White smoke sometimes appears at the outlet of the internal machine?

When the indoor air humidity is high, refrigeration operation is adopted, and white fog will be generated due to the humidity and temperature difference at the air outlet.

76. How to breathe with ventilation function?

Ventilation means that there is a special ventilation device to pump the dirty air in the room to the outside, so that negative pressure is generated in the room, and fresh air in the outside will automatically enter the room, thus achieving the purpose of ventilation, increasing the oxygen content in the room and refreshing the air.

77. How long will it take for the air conditioner to achieve the cooling effect?

It usually takes 5- 10 minutes, but it depends on the specific room structure, indoor tightness and outdoor ambient temperature, which are all related to the refrigeration effect of air conditioning.

78. Several lights of the air conditioner are flashing, and no operation can be performed.

Explain two possibilities: a, voltage instability, compressor overcurrent protection; Users can solve it by themselves, so it is recommended to take power first and then turn it on; B. If the first operation is ineffective, it may be that there is something wrong with the air conditioner and maintenance personnel need to come to the door to deal with it.

79. Why is the running light always flashing when the power supply is turned on and off? Why sometimes it flashes and sometimes it doesn't?

It is designed as standby indication state, and the flashing frequency is 1Hz, which is normal. The reason for not flashing may be interference, such as electromagnetic wave interference, infrared interference and so on. , such as mobile phones and fluorescent lamp rectifiers.

80. Select "Automatic" mode. Why does the wind rise and fall?

Automatic operation will change the mode and wind speed according to the set temperature and the current indoor temperature sensed by the machine, so the sound of wind speed change will also change.

8 1. Why does the air conditioner suddenly heat up when it is cooled?

A. When the weather is particularly hot and the air conditioner reaches or approaches the set temperature, the press stops, the outdoor fan rotates, and the indoor machine sends natural wind. Due to the high outdoor temperature, the natural wind is hot air. Users are advised to check whether the air conditioner is cooled after a few minutes.

B. Ask the user what mode to adjust. If it is in automatic mode, the temperature set by the air conditioner is higher than the room temperature, and the air conditioner cools. If it is below room temperature, the air conditioner will heat up.

C. if there is no such situation, let the maintenance personnel come to check.

82. Why doesn't the remote control work?

A. users are advised to check whether the air conditioner is turned on;

B. ask the user whether he is using air conditioning;

C. the user should replace the battery;

D let the user see whether the three lights of the air conditioner are flashing. If yes, ask the user to unplug the power supply and try again in a few minutes (in case of voltage instability);

E. none of the above will do. Go to the maintenance personnel for home inspection.

83. What is electric auxiliary heating? Do you need electricity?

When the air conditioner is used for heating, when the compressor fails to heat at low temperature or cannot be stopped, the indoor electric auxiliary heating is started, and the auxiliary heat pump is used for heating, and the effect is better. Electric auxiliary heating will consume electricity at first, and the energy will be conserved. How much heat is generated will consume how much electricity. Using polymer electric auxiliary heating device, the electric energy utilization rate is high. Once the normal heating is achieved, the electric auxiliary heating will be automatically turned off. Moreover, electric auxiliary heating is an independent operation key, and it is up to you to choose whether to turn it on or not.

84, the fan does not turn, boot protection?

It is possible that the air conditioning shaft is stuck, partly because of the high air humidity, or that the condensed water produced by air conditioning refrigeration or dehumidification flows into the motor bearing along the motor line, which leads to the rust of the fan.

85. Some cabinets with more than two cars are not plugged in. How do you explain this?

Because the instantaneous current of a cabinet with 2P or above is very high when it is started, which is 2-3 times of the working current, the maximum current that the general air-conditioning plug can bear is about 15A, but the general plug can't bear such a high current when it is started, which will lead to the burning of the power plug and even fire. In order to avoid such accidents, the National Security Bureau does not allow air conditioner manufacturers to be equipped with power plugs, and must use air switches or knives.

86. What is automatic mode?

Note: In automatic mode, the default setting temperature is 24 degrees. If the indoor temperature is higher than 24 degrees/kloc-0 degrees, the air conditioner will cool. If the indoor temperature is lower than 24 degrees/kloc-0 degrees, use air conditioning for heating.
