I have a Kitchenaid model KSRA22KKSS02. I’ve been dealing with a problem for the past few months where every 2 hours the "Over temperature reset" alarm starts going off. I’ve tested the temperature in the refrigerator side which is perfectly set at 38 degrees and is fine. I have noticed that food on the top shelf near the damper does tend to get some ice forming.
The problem I seem to be having is the freezer, which I have set at zero, is getting far too cold. Down to around negative 20 degrees. Even if I put liquor in there it tends to freeze up which is weird. I went ahead and replaced the termistor but that didn’t fix the problem. Any ideas on what it could be? I was thinking it could possibly be a control board issue. Thanks
