I have a Frigidaire FRS20ZRG-W6 which went warm on the fridge side.This a.m. I can hear the timer click and the fan blowing so I suspect the defrost heater or sensor. I removed the back freezer panel and manually defrosted the coils with a hair dryer this weekend and it cooled immediately so the fan is working, freezer seems fine.
I expect to have time late tonight to check the continuity on the sensor, but if anyone can tell me which suspect parts to buy in advance it would be a great help. Thanks
