Customer came home from grocery store to find fresh food section 52 degrees and freezer 15 degrees. Settings are for freezer 0 and fresh food 36. Upon arrival freezer was 3 and fresh food 36. Customer stated took several hours for unit to get back to better temps.
Ran diagnostic on display. Passed. Pulled unit out and checked low voltage power supply – 13.25. Back probed the voltage with a shunt load ( per fix your board ), voltage read 13.15 volts.
Inspecting motherboard did not see any resistors discolored or burnt.
Had a similar problem on another refrigerator that I changed out the evaporator thermistor and solved problem. Thinking I have same issue here.
We always replace both the freezer thermistor and the defrost thermistor at the same time. We see a lot of these refrigerators and we have been fooled to often. Since we have been doing this we have eliminated 95% of our recalls.
