Joe for Model Number ziss480driss My refrigerator is four years old, and gets heavy usage from family of 7. A day ago we notice that the freezer was not cooling as well as the main compartment. Everything else is working, the lights, a fan, etc. Could the problem be the inverter or the main board?
Answer Hi Joe. Is the evaporator fan turning? That motor with a thermistor is part # WR60X10074,without is part # WR60X10185. Is the top evaporator cover frosted up? If so you will need to change the defrost thermostat part # is WR50X29776. There is also a thermistor in there as well part # WR55X10025. These control the defrost time. Is the compressor on top and condenser fan turning? If the condenser coils are stopped up this will boil the freon. Clean the coils. The condenser fan motor is part # WR60X10209. Make sure nothing in the shelves or bins are holding the door's slightly open. Hope this helps. Thank you. Read More... Answered by AppliancePartsPros.com | Friday, August 12, 2011
