Mechanical adjustment electric pressure cooker 0 1 no power supply.
A. Generally, it means that after the power supply is turned on, the light does not light up and it does not generate heat. This fault mainly lies in the fault of power supply line. Need to test whether the fuse has blown. If so, install the corresponding fuse and the fault can be eliminated. If the fuse is not blown, the 145 degree thermostat in the center of the pot bottom will fail and be disconnected, and this kind of fault will also occur.
B. Focus on whether the power cord is blocked and whether the source line interface position is blocked due to melting. You can test it with a multimeter and make sure it can be overhauled.
The power indicator is on, but it is not hot.
A. It usually appears on the heating plate, because the heating plate has burned out and needs to be replaced with a new one. Don't use it if the price is high.
B. After heating for a period of time, keep warm before the water boils. One way is to turn the switch, that is, the timer part is not in good contact. Although the cooking part was twisted, it was not connected, so the circuit was controlled at 60 degrees by the insulating switch.
C. It is also possible that the pressure switch is out of order, resulting in poor contact of the timer. But when the pressure didn't come up, the pressure switch had failed (tripped), leaving the circuit in a state of heat preservation and the water couldn't be turned on.
03 heating and power failure
A. After the electric pressure cooker is turned on and heated, the whole machine will automatically turn off the power supply and the light will not light up. It should be the thermostat at the bottom of the cooker 145 degrees, which leads to failure.
B. Turn off the power supply only when the temperature is not reached. After the temperature drops, it can be turned on normally: if it is, it can be changed to temperature control.
04 Timer does not turn
A. In use, it is sometimes found that the rice is burnt. After inspection, it was found that the timer was faulty. There are two kinds of clockwork timer and motor timer, called A and B for short.
B. When this kind of fault occurs in the type A timer pressure cooker, on the one hand, the internal timer stops rotating, indicating that it has been damaged; On the other hand, due to the intrusion of some small animals, the feces left behind stuck the rotating cone in the timer, and the subsequent failures were eliminated by cleaning up the debris.
When the pressure cooker of C.B timer fails, the main reason is that the small motor in the timer has burned out and can't rotate or disconnect within the specified holding time; B the rotation of the timer is controlled by the pressure switch. Therefore, we must pay attention to whether the pressure switch will fail, or whether the pot itself will leak, and whether the pressure switch will jump when the pressure in the pot is insufficient.
05 lid leaks
A. The leakage of the side cover is caused by poor sealing. The sealing surface of the electric pressure cooker consists of a sealing ring and the upper end surface of the inner container. If there is something wrong with this contact surface, the seal will fail and the air will leak.
B food residues stick to the upper end face of the sealing ring or liner, resulting in poor sealing.
C. the sealing ring is aging and cannot be sealed.
D. There are foreign objects at the bottom of the rice cooker, resulting in uneven inner container.
06 cooked uncooked rice
A. The pressure switch is dead: as soon as the switch is turned on, the heating lamp will light up for about one or two minutes, and then immediately jump to the green pressure maintaining lamp. The water is just a little hot.
B the tripping temperature of the sensor is too low: turn on the switch and cook for a few minutes. If no pressure is applied, jump to keep the pressure.
C. When the pressure is very low, the pressure switch will trip: turn on the switch and cook for a few minutes. When there is slight pressure in the pot, jump to maintain the pressure.
