What Are the Causes of Car Air Conditioning Compressor Failure?
1 Answers
Car air conditioning not blowing air can be caused by blower motor failure, clogged air filter, or control system malfunction. Car air conditioning refrigeration system: consists of compressor, condenser, receiver-drier, expansion valve, evaporator, and blower motor, etc. These components are connected by copper pipes and high-pressure rubber hoses to form a sealed system. When the refrigeration system operates, refrigerant circulates in different states within this sealed system. Blower motor failure: The car blower motor is a crucial component for air conditioning airflow. If the air conditioning compressor fails during operation, the car air conditioning will definitely not blow air. Overheating damage to the internal coil or capacitor failure are significant causes of blower motor failure. You can turn the car air conditioning to maximum and listen for the blower motor sound. Clogged air filter: A clogged air filter is a common and major reason for air conditioning not blowing air. During operation, the car air conditioning absorbs many impurities from the air, leading to filter clogging. If the air conditioning stops blowing air, you can remove the air filter to check if it's clean. Control system malfunction: If neither the blower motor nor the air filter is causing the air conditioning to stop blowing air, then the issue might be with the air door, air conditioning computer, or control switch. Control system switches generally don't fail easily.
