What Causes the Car Compressor to Engage but Not Cool?
1 Answers
Reasons why a car air conditioning compressor may engage but not cool include: 1. Issues with the compressor clutch. 2. Problems with the compressor control circuit. 3. A faulty temperature control sensor in the car air conditioning system. 4. Insufficient or no refrigerant in the compressor. Additional information: If the measured high pressure is slightly low and the low pressure is low or too low, there are two possible causes: 1. Insufficient refrigerant in the system, which should be replenished to the appropriate level. 2. Blockage caused by deformation of the high-pressure pipeline due to external force or blockage in the receiver-drier, with a noticeable temperature difference between the inlet and outlet of the receiver-drier.
