I'm having some trouble here. Both the freezer and fridge temp displays are doing strange things. There are no error codes. Diagnostic mode seems to work properly. In normal operation both displays seem to be only being displaying set points not actual temp while the actual temp in both the freezer and fridge seem erratic. Currently If I set the fridge to 37 and close the door the display moves to 36 in a blink then wont change while the shelf thermometer is much higher. If I leave both sides closed for a while the actual temp will drop way lower then the set points again this is both sides and no change in the displays. I'm leaning toward replacing the control board but I'd love to hear from someone with more experience before I go for an expensive board.
