Norcold has a good service bulletin that you can download, maybe from Bryant. You can check several things using it. There are a couple fuses on the power board on back of refer - could be one of them, could be the power board itself. Service bulletin is very useful.
Ours does this like John Wayne said. If it doesn't start you might take your air compressor and blow air around the motor, the heater part, and the control board, anything in that area. After I do that mine goes back to running correctly.
