What is the reason why the air conditioner doesn't cool?

Common reasons why air conditioners are not cooled are as follows:

1, due to the high external temperature.

Change the use environment of the outdoor unit, add some sunshade equipment to the outdoor unit to avoid high temperature baking. (stay away from high temperature environment or make the air around the outdoor unit easier to circulate)?

The air conditioner has not been cleaned for a long time.

If the air conditioner is not washed for a long time, there will be a lot of dust and garbage on the radiator, and the heat dissipation effect is not good, resulting in the air conditioner not being cold. Therefore, the air conditioner should be taken apart and cleaned every once in a while to ensure the cooling effect of the air conditioner.

3, refrigerant leakage

The leakage of refrigerant in the air conditioner will reduce the refrigeration effect, so it is necessary to add refrigerant and check the leakage point.

4, air conditioning compressor failure

There are three main reasons for the compressor not turning: excessive current, reduced or damaged working capacitor capacity, improper temperature control or damaged temperature detection probe. Maintenance difficulties, it is recommended to contact after-sales or professional maintenance personnel to deal with them.
