Have a side by side fridge that was experiencing Icing of the condenser, and the freezer side started to run warm and not make ice. Defrosted unit and reset rear panels that had been shifted by ice build up. Restarted fridge and using a thermometer, I got results that ranged from 24' to 35' F, still can't use as a freezer. some thoughts I checked, the fan works the ice maker system works when there is ice, fridge is still cold. Any ideas, like defroster, thermistor, main board etc. Need advice, thanks, Mike.
