As the temperature gradually rises and the weather gets hotter, car owners who drive have gradually started to turn on their car air conditioners. Many car owners found that the air conditioner did not cool after turning it on. What is going on? What are the reasons why the car air conditioner does not cool?

Reasons why the car air conditioner does not cool

1. Refrigerant leakage or poor refrigerant quality: Some unscrupulous car dealers begin selling refrigerants of substandard quality. If the reason your car air conditioner does not cool is due to the use of this refrigerant, then just replace it with a qualified car air conditioner refrigerant. If you are sure that there is no problem with the car air-conditioning refrigerant, the car's indoor and outdoor units are working, the compressor is also working, but the car air-conditioning has no cooling effect, it may be caused by a car air-conditioning refrigerant leak.

2. The compressor capacitor is damaged or defective: If you find that after the car air conditioner is started, the internal and external units of the car are working normally, but the compressor does not rotate and causes overheating, then it is very likely that the car compressor capacitor is damaged or the quality is not up to standard, causing the compressor to not work. If this problem is confirmed, go to a professional repair station for replacement.

3. The car air conditioner's room temperature sensor reaches the set temperature: In fact, car air conditioners are the same as home indoor air conditioners. If the owner finds that the car air conditioner no longer cools after reaching a certain temperature and enters a shutdown state when driving the vehicle using the car air conditioner, it may be that the air conditioner's room temperature sensor has reached the set temperature.

4. Defective remote control or air conditioning receiver: If your car air conditioner does not respond after turning it on, or it does not work from time to time, you need to check whether the remote control or air conditioning receiver is "acting badly".

5. Failure of the air conditioner's indoor or outdoor control panel: If there is no response after the car air conditioner is turned on or the car air conditioner "moves randomly", it may be due to a failure of the car air conditioner's indoor and outdoor control panel. At this time, going to a maintenance point to repair the car air conditioner's indoor and outdoor units can solve the problem.

6. The live and neutral wires of the air conditioner power supply are connected reversely: This phenomenon usually only occurs when the car air conditioner is installed. If everything is normal after the car air conditioner is installed, this phenomenon can be eliminated. If the consumer buys a used car and the air conditioner fails to cool, if it is not due to the above situation, you should check whether the live and neutral wires of the air conditioner power supply are connected incorrectly. Because some car owners will clean the vehicle before selling it, and some people will even replace car parts, it is inevitable that the wires will be connected incorrectly. Just change them back.

7. Damage to the indoor or outdoor fan or capacitor: If the exhaust temperature of the car is too high or the high pressure is too high, the outdoor fan of the car may be damaged; if the indoor unit is frosted, the indoor fan of the car air conditioner is damaged. If it is determined that the reason why the car air conditioner does not cool is due to damage to the indoor or outdoor fan or capacitor of the car, please ask a professional to continue repairing and replacing it.

In such a hot season, the failure of car air conditioning to cool is a very headache problem for many car owners. However, as long as you find out the reason why the car air conditioner is not cooling, you can successfully solve the problem of not cooling. Several reasons and solutions are introduced above. Some of them can be repaired by yourself, while others need to be repaired in a special car repair shop in time. You might as well try to find the reason yourself.
