I have replaced the temp sensor in the freezer coil and the defrost thermostat. This did nothing. The fan will kick on but the compressor will not. There is no current to the compressor relay or the overload. Not sure where to go from here? Could it be another sensor or in the circuit board. I have one terminal on the bottom left of the board with 120v(brown wire) and 1 terminal on the bottom right (Gray Wire) with 120v current. Looking for direction.
