What Causes Mazda Compressor Abnormal Noise?

[LaEmery]

Introduction to the causes of Mazda compressor abnormal noise: 1. Belt noise: The air conditioning compressor is usually driven by the engine crankshaft via a belt. When the belt is loose, aged, severely worn, or the tensioner's tension is insufficient, the belt may slip or shake during operation, resulting in a rattling noise. 2. Damaged air conditioning compressor: The refrigerant in the air conditioning system needs to be compressed by the compressor, converting low-temperature, low-pressure refrigerant into high-temperature, high-pressure gas, which is then liquefied and cooled by the condenser. When the internal components of the compressor are damaged, it can also produce a rattling noise. 3. Debris in the air duct: The cold air blown by the air conditioning system is delivered into the car by the blower after the normal air is cooled by the evaporator. When there is debris (such as leaves or twigs) in the air duct, the debris may rotate with the blower's airflow and repeatedly hit the air filter, causing a rattling noise.
