Hi. When my compressor is switched on it makes a
humming noise and won’t start up.
I would appreciate any information you might have
im regards to the problem
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
