1. How to maintain Haier air conditioner without refrigeration?

1, refrigerant leakage. The performance is that both the internal and external machines are working, and the compressor is working, but it is not working.

2. The compressor does not work due to damaged or defective capacitors (the phenomenon is similar to the above, but the compressor does not turn and is overheated).

3. The resistance value of the temperature sensor changes at room temperature, causing the outdoor unit of the air conditioner to fail to operate (the phenomenon is the same as stopping the air conditioner after reaching the set temperature).

4. The remote control is not good or the air conditioner receiver is not good.

5. The four-way valve (the single cooler has no such fault) or the compressor leaks gas at high and low pressure, and the air conditioner works but has no effect (the phenomenon is the same as the first one).

6. The control panel of the indoor unit or outdoor unit of the air conditioner fails, resulting in the air conditioner not cooling.

7. The zero line of the air conditioning power supply is connected backwards. A few air conditioners will have this kind of fault, usually when they are installed.

8. The fan of the internal machine or external machine is damaged (there are many bad capacitors). (The fault fan of the external machine is characterized by high exhaust temperature or high pressure protection. The bad fan of the internal machine is characterized by frosting of the internal machine, and the external machine has been working, which may get moisture into the equipment.

Second, Haier air conditioning refrigeration troubleshooting methods:

1. First, check whether the air conditioner works normally, including the indoor unit and the outdoor unit, especially the compressor of the outdoor unit. As long as one of them doesn't work properly, you have to ask the master to fix it.

2. Then check the filter screen of the air conditioner. If the air conditioner starts normally, but it can't disperse the cold air, it is likely that there is too much dust on the filter screen. It's best to spray it with that special filter cleaner.

3. Check whether the refrigerant is insufficient, which is called freon. If it is not enough, add freon. Most of the reasons for this lack of refrigeration are air conditioners that have been used for three or four years, and most of them are normal phenomena, which belong to the normal consumption of air conditioner refrigerants (that is, freon or snow) caused by long-term use, but this is only manifested in the fact that the air conditioner is not fully cooled compared with the previous normal situation, and will not be completely cooled because of insufficient pressure. At the same time, check whether there is air leakage in the cold circulation system. If there is air leakage, it must be repaired.

4. If the air conditioner can work normally without the above problems, then check the working condition of the air conditioner fan. If the fan air volume is small, it may be that the fan motor is old and needs to be replaced with a new fan motor.

5. If the ventilation duct of the air conditioner is installed for a long time, the effect of indoor heat transfer to the outdoor may be poor, resulting in the situation that the refrigeration is not obvious. It's best to find a better location to reinstall and minimize ventilation pipes.

6. If the air conditioner runs normally, everything else is fine, but there is no air conditioner in the room. Only when the air conditioner blower is turned on can there be air conditioning, probably because the horsepower of the air conditioner is too small and the room space is too large. At this time, it is best to change the air conditioner with a higher horsepower. This is also one of the common reasons for insufficient cooling (poor cooling effect), but there are many reasons for this lack of cooling, such as: rooms with large area of low-power air conditioning pipes, some rooms are relatively closed (such as doors and windows are wide open) or there is a heat source in the room. Of course, the western drying of glass houses is also one of the heat sources.

7. I have met such users. At home, I always say that the air conditioner is not cold enough. It was found to be normal during the inspection. I checked it several times and found no problems. Later, in an inspection, it was finally found that the power supply voltage there was unstable and often failed to reach the normal voltage, especially during the peak period. We must solve this problem by providing a stable voltage.

8. The outdoor environment temperature is too high, resulting in the air conditioner not cooling. This kind of uncooled situation is common when our outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high. For example, for the sake of beauty, installing an outdoor unit in a hidden small space or even putting multiple outdoor units in a small space can easily make the air in the small space where the outdoor units are located not circulate, so that the heat emitted by the radiator cannot flow away, resulting in the air conditioner not cooling.

Maintenance process: customers apply for repair-> the company registers and accepts the dispatched workers-> technicians come to contact customers-> on-site inspection and show the price list-> after the repair, users fill in the warranty form and confirm their signatures-> the company pays a return visit to customers-> customers confirm the repair results-> enter the warranty.

1: 24-hour city service, no rest on Saturday and Sunday.

2. In strict accordance with the appointment time on-site service, keep the reputation and keep the appointment.

3. On-site maintenance requires inspection first, then quotation, face-to-face maintenance, charged maintenance, and free maintenance.

Description of cost composition: total cost = basic maintenance cost+replacement time cost+parts cost.

Maintenance instructions:

1, we provide on-site service, quote first, then repair. If you are not satisfied with the quotation, you can give up the maintenance and pay only 3050 yuan for the inspection fee! 2. If the company needs to take the machine out of the car, the fare will be calculated separately. 3. If the company's customers need to issue invoices, add 10% tax. 4. The overall cost of batch repair and maintenance for unit customers can be reduced by 30%. 5. The inspection fee of 3050 yuan is charged in and around the Fifth Ring Road, and the door-to-door fee in the outer suburbs is negotiable.
