What Causes High Low Pressure and Low High Pressure in Car AC Leading to No Cooling?
1 Answers
Reasons for car AC not cooling include insufficient refrigerant and sensor malfunction. Below are detailed explanations regarding car AC not cooling: Insufficient Refrigerant: The lack of cooling is due to insufficient refrigerant in the compressor. The causes of high low pressure and low high pressure are that the displacement produced by the compressor does not meet the requirements, leading to expansion valve failure. Timely maintenance is required. If the refrigerant is low, some refrigerant can be added. Compressor failure requires checking for blockages or leaks. Blockages are caused by excessive dirt and need cleaning. If there is a leak, the leak point needs to be repaired. Sensor Malfunction: If a certain temperature zone, such as the refrigerated compartment or variable temperature compartment, is not cooling, check whether the sensor parameters of that temperature zone are normal.
