FLSC238DS1 with inverter compressor

[AmTec Services]

Went out on this call. The unit was unplugged when I arrived. Cust says the fridge keeps tripping the breaker. Plugged it in and comp starts up, drawing 1.9 amps. Runs for about 3 min and then comp stops. Restarts for about 30 sec and control beeps 3 times and the breaker trips. Never did see high amps, but my meter is not fast on response. Reset the breaker and try again. Comp starts and runs 30-40 secs and trips breaker again. (3 beeps again). This is my first inverter drive fridge, but worked on many Carrier and Trane inverter drive a/c systems.

Need some advise from the masters.

The only check you can do is ohm out the windings on the compressor. I don't have the spec but that's on the tech sheet. All three windings should have exactly the same resistance. If not, the compressor is bad. If the windings check good, then replace the inverter board.
