Hi Bill,

What kind of compressor is this?

If it’s an electrical – please check the electro motor, the wiring and the main contactors.

It sounds like a problem with one of the phases – either in the contactor, the wiring, or one of the windings in the electro motor.

Good luck! Let me know what you find
