Tonya for Model Number pds20mbrbb Temp controls don't work. Try to set fridge &/or freezer temp to recommended levels (or any levels) but the display just reverts back to 70 for fridge & 40 or so for freezer. Have heard online suggestions that mainboard may have circuits damaged or that the board is bad, was recalled & may be replaced under warranty. Not sure if it's still under warranty. Guess I can find out. But if replacing the mainboard (which I heard is really easy) then why not do that? Any ideas would be appreciated.
Answer Hello Tonya. It doews lead to the main board if the display board is good on 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 Read More...
