I have replaced thermostat but ice still build up. Where would I find defrost timer, if I need to replace it? How to check if it is faulty?
Answer Hello Joe. Most likely, the heater is bad on the unit. But if it is good, then the timer is all that is left. It is located inside the fresh food control panel section.
Looking at my defrost timer the small shaft is not turning. In addition I hear a slight grinding noise from it. I suspect that the timer is inop. Knowing that it will not defrost the evaporator until I get the new timer installed. Will it affect the cooling of the refrigerator or freezer short term ?
Answer Hi Chuck. Yes look at the top of the freezer and above the cover is a evaporator that has the defrost heater part # WR51X322 and the defrost thermostat part # WR50X45. Then defrost timer part # WR9X502 sends the voltage to the thermostat and then if it is closed , it sends it to the heater to defrost the evaporator. Over and Over for approx. 25 minutes until the until the thermostat purposely opens at approx 45° to protect the cavity. So if there is frost on the top cover, now the air flow is blocked and you are into a no coo. until you either diagnose with a Volt/ohm meter and replace the correct parts needed or turn off the unit and leave the doors open all day wit a fan blowing into the freezer evaporator area . this will thaw out and you need to keep an eye on the units drain pan to make sure it dos not over flow. Thank You.
The GFI outlet Trips when I turn the fridge (dial) on.
Answer Hello Ramon. Try running the unit in an outlet that is not a GFI outlet. If the unit runs fine, then the outlet is bad. If not, then you will need to look for a short on the unit. Check for a loose or broken wire in the unit. Also, look for a bad connection, or gounded wire. Turn the timer WR9X502 and see if the unit runs properly. If so, you may have a short in the defrost cycle. Hope this helps.
