Why does the compressor cycle on and off?

Written by admin on February 25, 2023. Posted in Uncategorized.

Low refrigerant charge causes rapid cycling. Drive belts and blower resistors do not affect compressor cycling. An excessive air gap may prevent the clutch from engaging.

What to do if my auto A/C Compressor fails ?

Technically the compressor can be rebuilt ,it is recommended to replace the entire compressor. If there was a major internal compressor failure the entire system must be inspected for debris(metal from internal compressor components).After an internal compressor failure, it is recommended to replace the A/C condenser(Specially if it is a modern Parallel Flow type) and the drier, to avoid contamination of the brand new air conditioning compressor. Also, the system should be flushed to avoid contamination.
