What Are the Consequences of a Clogged Car Air Conditioning Drain Pipe?
1 Answers
When the car air conditioning drain pipe is clogged, the high pressure will rise rapidly and the low pressure will drop quickly after startup. Then the pressure switch will activate protection, cutting off the clutch and stopping the air conditioning. After startup, the pressure difference between high and low will increase, the compressor exhaust temperature will rise, and the air from the air conditioning evaporator will not be cold. Main causes: At the location of the clog, you can feel a clear boundary between hot and cold by touching it. It is unlikely for the car air conditioning to clog in the pipes; it mainly occurs in high-pressure circuits such as the expansion valve, receiver-drier, and condenser. Expansion valve clogging: Clogging of the expansion valve is the most common issue because the expansion valve has the smallest diameter, and its inlet is equipped with a filter screen where debris from the system can accumulate and cause blockage.
