What Causes Frequent Tripping of a Car's Compressor?
1 Answers
Frequent on-off cycling of a car's air conditioning compressor is a type of compressor protection fault. There are three forms of air conditioning compressor protection: overheating protection, overcooling protection, and overcurrent protection. The details are as follows: 1. Overheating protection: This occurs after the system is low on refrigerant and runs for a long time; the system is blocked (ice blockage or dirt blockage) and runs for a long time; the ambient temperature is too high; or the compressor's overheating protection device is faulty. Once the compressor's temperature decreases, it can start again. Generally, you can quickly cool the compressor by pouring water on it and then investigate the cause of the protection. 2. Overcooling protection: This happens when the ambient temperature is extremely low (below -15 degrees Celsius). 3. Overcurrent protection: This occurs due to a faulty starter capacitor; the system is severely low on refrigerant and runs for a long time; the voltage is too low; or the compressor itself is faulty.
