Why is the air conditioning in a new car not cooling?
1 Answers
The reasons why the air conditioning in a car may not be cooling include: the air conditioning is broken; power failure causing the air conditioning not to cool; the air conditioning automatically stops running based on the temperature sensor. Specific inspection methods are: 1. Check the compressor belt: If the belt is too loose, it should be adjusted, otherwise it can easily cause poor cooling in the air conditioning system. Check the hose connections of the air conditioning system for oil traces. If leaks are found, promptly go to a repair shop to resolve the issue. 2. Clean the condenser: Keeping the surface of the car condenser clean facilitates the dissipation of heat to the outside. Regularly cleaning the condenser surface can significantly improve the cooling effect of the air conditioning system. 3. Check the refrigerant level: Inspect the refrigerant level. The sight glass is usually installed on the dryer's cover. Run the engine and air conditioning system, and observe the flow of refrigerant through the sight glass. If the air conditioner is working normally, you can see clear refrigerant continuously flowing, occasionally with small bubbles during high temperatures, and small bubbles visible when the air conditioning system is turned off. 4. Ensure sufficient refrigerant: This can be estimated by feeling the temperature difference between the inlet and outlet pipes of the dryer, or by using a manifold pressure gauge for detection.
