The low side assembly unit in the freezer completely freezes up to be a solid block of ice & stops the fan from turning. What causes this?Door seals are ok. Items freeze ok, but when the unit becomes a solid block of ice the items in the freezer start to thaw. Please help. Regards...Steve.

ANSWER Hi Steve. Almost anytime the evaporator freezes over it is a defrost issue. Clipped to the top of the coils is a defrost thermostat part # WR50X10010 that has to close under frozen temperatures and also open under too high of temperatures to protect the defrost heater under the coils from melting the cabinet sides. The heater is part # WR51X10004. The defrost timer part # WR9X541 will allow the compressor to run approx. 6-hrs to cool the unit per temp setting. Then it will click into the 25 min. (approx) defrost time. This sends 120 vac to one side of the thermostat to be closed and then send it directly to the heater assy. So If you go to the center of the defrost timer with a large blade screwdriver to advance it into the defrost cycle, this is the way to check it. If the detent turned hard, more than likely the timer has internal physical issues and needs replaced. Or if when you turn it and then you stop at the first "heavy" click. You use the volt meter to test to see if it sends the 120 vac to the defrost thermostat. With a ohm meter test to see if the thermostat is closed (check w/no power). The heater will ohm out to approx. 8-11 ohms if good. Thank You.
