I have a copeland semi hermetic compressor out of a reach in freezer. model number is kamb 007e caa 800. when I plug in the freezer, the compressor tries to start, but after 4-5 seconds, the circut breaker tripps. I ohmed out the windings and I have resistance, and none of the wingings are grounded out. I checked the windings on the condenser fan, and they are good. I noticed there was no refrigerant in the freezer at all, would that cause the breaker to trip? a few technicians diagnosed it as a compressor burnout, and I want to confirm that before I have it re built.
