Air conditioning trip repair

Air conditioning trip repair Whether it is in hot summer or cold winter, it is inseparable from air conditioning. Every household has also installed air conditioning. Air conditioners, as an electronic product, are used for too long or improper operation will cause the air conditioner to malfunction. Tripping like an air conditioner is a very common fault. There is a problem with the air conditioner circuit. The air conditioner turns on self-protection mode and automatically powers off. If it is not handled in time, the air conditioner is unusable. The reason why the air conditioner trips is described below. 1. The fuse in the air-conditioning circuit is blown out, or the power switch has poor contact. At present, many households only use one power supply, and the power supply of the air conditioner is abnormal due to the abnormal operation of other electrical appliances, and the air conditioner automatically turns off the power supply. 2. The power supply used by the air conditioner is too low. When the voltage is lower than 10% of the single-phase normal voltage 220v, that is, 198v or less, the refrigeration compressor in the air conditioner is difficult to start. When the air conditioner is turned on, the air conditioner will trip. 3. The dial on the temperature controller is not dialed to the proper position, such as dialing to a higher position, when the power is connected, the temperature in the air-conditioned room has not reached the upper limit of the set temperature, the compressor If it cannot start running, the air conditioner will also trip. 4. The high-pressure relay operates, such as the condensation pressure is too high, the high-pressure relay is activated, and the operation of the compressor is stopped. 5. The low-pressure relay operates, such as insufficient refrigerant in the refrigeration system, which causes the compressor suction pressure to be too low, causing the low-pressure relay to operate and stop the compressor. 6. When the current of the compressor and fan motor is too large, the overload protection relay is activated to cut off the power supply. Air conditioner tripping is a self-protection mechanism. The fault must be eliminated before the air conditioner can be started normally. In addition, the daily maintenance of air conditioners will also reduce the occurrence of malfunctions.
