An unknown technician repairs air conditioner
The reasons and solutions for the air conditioner not heating up. You will know how to repair the air conditioner after reading it!
If the air conditioner's refrigerant is insufficient or leaked, it will cause the air conditioner to fail to heat up. Therefore, when we are repairing, we must first check the refrigerant condition and then carry out repairs according to the situation. In addition, we can also check whether the compressor is damaged or aging. If it is a compressor problem, you must replace the new compressor in time. If it is another problem, we can just check and repair the compressor circuit.

If the temperature difference in indoor and outdoor temperatures is too large, it will cause the air conditioner to not be able to heat normally, because when the temperature difference between indoor and outdoor temperatures is too large, the air will flow slowly, resulting in the inability to dissipate heat, which will cause this situation. Therefore, when we are repairing, we must first check the temperature difference between indoor and outdoors? Then follow the corresponding treatment to solve it! For example, in winter, you can open the windows to allow the indoor air to circulate or use electric heating and other equipment to solve this problem!
If the filter we use is dirty, it will also cause our central air conditioner to not work normally! Because the cleanliness of the filter will affect its heat dissipation effect and its working performance~ So when we find that our central air conditioner cannot work normally, we can check whether the filter is clean and whether it needs to be cleaned~
If the voltage we use is too low, it will also prevent our central air conditioner from working properly~ Because the voltage is too low, the current will become smaller, which will affect the normal operation of the circuit~ Therefore, we must regularly install some protective devices on the power sockets at home to avoid this situation! Also, you should pay attention to the safety of electricity at home to avoid electric shock.
First, press the switch key with the remote control (some models hold the switch key for 3 seconds) to observe whether the display light of the remote control is lit normally; secondly, observe whether there is cold air blowing or the air temperature is low at the air outlet of the outdoor unit; finally check whether there is frosting on the evaporator in the outdoor unit (under normal circumstances, the frost layer on the surface of the evaporator is thin and easy to melt).
