What causes compressor clutch failure?

What causes compressor clutch failure?

With a wrong charge the pressure switches will cause the compressor to constantly engage and disengage. If there is not enough charge the compressor will overheat due to a lack of oil circulating. If there is too much refrigerant, the head pressure will run higher, causing overheating which leads to clutch failure.

Should I replace the AC clutch or the whole compressor?

The primary reason to replace an entire A/C compressor and clutch assembly is for better long-term reliability. The AC clutch pulley might be what needs replacement, but it’s likely to have done some damage to the compressor on its way out.

Do AC clutches wear out?

When you turn on the air conditioning, the clutch engages and begins spinning to transfer the power. The compressor clutch also keeps the air conditioning from running constantly. If it ran all the time, you would notice a decrease in fuel economy and have worn-out air conditioning components more often.

What should I do if AC compressor clutch is not engaging?

Check the wiring to the clutch – If wires aren’t connected properly this could impact how the compressor is working. Wire need to be connected and in good condition to provide enough power. (In addition the high pressure switch and evaporator temperature sensor could be faulty or have loose wires)

How much does it cost to replace an AC clutch?

Between $610 and $664 is the average cost for an AC compressor clutch replacement. Labor costs are between $184 and $232 while parts are between $426 and $432.
