TEMP. BOARD DON)T LIGHT UP.
Answer Hello Frank,
The temp board not lighting up would either be the temp board or the main control board. Check the temp board to make sure that you are getting 12 vdc to the board. If you are then you would need to replace the temp board if not then you would need to replace the main control board.
My refrigerator is freezing everything. I have turned the temp down, but it hasn't warmed up at all.
Answer Hello Craig. You need to test the thermistors inside the unit and make sure they are good. They should read around 5k at room temp. If bad you will need to replace the thermistors in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
