If the indoor temperature is higher than the outdoor one, or the indoor temperature is higher than the set temperature, the air conditioner will not start;
Solution: Test the temperature comparison between indoor and outdoor to check whether the indoor temperature is too high.
The voltage of the air conditioner is unstable, and the compressor generally cannot start normally;
Solution: Use a multimeter to check whether the voltage and current are stable in the rated range, and if it is unstable, you can install a voltage regulator.
The external ambient temperature is too low, and the water inside the air conditioner freezes the fan, resulting in the failure to operate normally;
Solution: Check whether the fan of the outdoor unit can run normally, if it freezes, you can pour some hot water, pay attention not to pour it on the line.
If it is not cleaned for a long time, it will cause rust aging or the dust will be too thick to operate normally;
Solution: Open the shell of the outdoor unit, observe whether the inside is aging and rusty, or the dust is too thick to cause the fan to run, and clean the air conditioner regularly.
damage to the refrigeration system of the air conditioner;
Solution: Use a tester to check whether it is a short circuit in the line or a damage to the compressor.
When the air conditioner is generally not running, you can observe the screen of the air conditioner display, and when there is a failure, there will be an error code, and you can deal with it according to the instructions of the air conditioner manual, if the air conditioner does not display, it may be a problem with the line and needs to be repaired.
