Did it ever work on the circuit you have it on now?

Sound like too many appliances drawing power from the circuit before it gets to the compressor, or the start capacitor is failing or has failed, or the motor itself might be flawed.

Before you check any of these further, unplug the unit, open the drain valve to drain the tank to zero, and plug it back in. What happens then?

Cheers,
