What could be the reason when a car's air conditioning suddenly stops responding?
1 Answers
The reasons why a car's air conditioning suddenly stops responding: 1. Possible pipe blockage, excessively high pressure or low pressure; 2. Poor heat dissipation; 3. Expansion valve blockage; 4. Too little or too much refrigerant; 5. Compressor not operating. Below are related solutions: 1. Check the pressure of the refrigerant. If the pressure is too low, the refrigerant is insufficient and needs to be replenished. Insufficient refrigerant will affect the air conditioning's cooling. 2. Check whether the blower of the air conditioning system is operating normally and the amount of air flow. If there is a problem with the blower, the cold air from the air conditioning system cannot be delivered to the car interior in time, resulting in no cold air from the air conditioning vents. 3. Check whether the surface of the air conditioning system's evaporator is too dirty. If the surface of the evaporator is too dirty, the cold air from the air conditioning vents will decrease because the cold air is mainly produced by the evaporator. 4. The working cycle of the refrigerant in the pipes must rely on the compressor for transportation. If the compressor cannot operate due to abnormal refrigerant pressure, circuit failure, temperature sensor damage, or burned compressor electromagnetic clutch, the cooling will be insufficient. It is recommended to replace the temperature sensor or electromagnetic clutch.
