This morning after getting milk for my coffee, the refrigerator starting beeping like when the door is left ajar. I noticed the temperature display was OK for the freezer but the refrigerator temp was above the desired temp and after watching it, it kept getting warmer. The refrigerator was obviously not cooling.
While moving things out to another refrigerator after several door openings the interior light was not lit up. Depressing the door switch did nothing. After several more door opening (to include one to see if the bulb was burnt out –it was not) the light started working but when the door was closed (or the door switch was pressed) the light stayed on.
The fan for the refrigerator was also noticed to not be running. Since the light was not function correctly and the fan was not running, and both are controlled by the PC board, I suspect there is a problem with the PCB and not the light, light switch, or fan motor.
I do not know what voltage outputs are, nor ohm values to check for continuity on any components/wires… I can only deduct that the PCB is the most likely failure to effect fan and interior light of the refrigerator.
The freezer works perfectly, temp, temp control, interior light.
