Product review (1 stars): Sold a defective main board.
Received a defective board.  The original kept the freezer cold but would not open the damper unless putting in turbo cool mode. Installed new main board just received and compressor will not come on.  Waited 4 hours in case unit started in defrost mode. Still not turning on compressor.  Pulled new board and reinstalled old unit and comoressor fires right up.  Will be contacting sell for replacement.
