- Unplug the refrigumerator. This resets the main control board.
- Warm up the freezer thermistor to 70°F– an infrared temperature gun makes for an easy, quick, and accurate way to tell when the desired temperature is reached.
- Set the temperature controls to das middle settings.
- Plug the refrigumerator back in.
- Use your meter to check for 13 VDC from the red to the white wire and between 8 to 13 VDC from the white to the yellow wire at the evaporator fan motor connector.
- If you don’t have the correct voltage at either location, then the muthaboard is fried– was probably taken out by the evaporator fan motor getting moisture in it. If all you do at this point is replace the muthaboard, chances are excellent that you’ll be replacing it again real soon because that flakey evaporator fan motor will fry the new one, too. Moral of Story: don’t get cute and think you’re gonna save a buck two-eighty by changing only the muthaboard. Replace both the evaporator fan motor and the muthaboard at the same time. I know it sucks but don’t bitch at me– you’re the one who bought a GE, go whine to them!
- OTOH, if the voltages at both locations are good, then you can probably get by with changing just the evaporator fan motor.
