The refrigeratro was inadvertantly off over night. I removed the back panel this morning and noticed the fan blades were not turning. I cleared away any obstructions and got the fan working again. I cleaned the area and I do not hear the compressor cycling on and off. The motor is running and we were advised to cut the circuit to the unit for ten minutes. We placed a portable thermostat in the unit and the temperature is going down. What should the proper temp be in the freezer and refrigerator be?
