I have checked out the heater etc.by the test method used to tell the control board to start defrost and everything mechanical works. What tells the board when to defrost. Door openings? once a day?

Is their a way to tell if the boar is recieving the compressor on and off time as well as the door openings? Or do i just asume it is the board and replace it?

If not test the defrost thermostat first (aka bi-metal) with an ohm meter. If it has continuity ohm the defrost heater if it has continuity then the board is the problem. Nat

I now believe either the board is bad or the wires connecting the compressor or the door opening counter are comprimised. Since the compressor shuts off during defrost I will assume they are ok. and check the door opening connection. If this is ok does this mean the board is bad?
