Where is the defrost timer located in the GE Adora fridge?
This unit does not have a defrost timer. The defrost control is part of the main control board WR55X10942 for your unit. If you are having a defrost issue you will want to check the defrost thermostat WR50X10068 to make sure that it is not open. Check the defrost heater WR51X10042 to make sure that it has continuity. Check the defrost thermistor WR55X10025 resistance. The resistance of the thermistor at 0 degrees should be 42.2K ohms of resistance, at 37 degrees would be 14.4K ohms and 77 degrees would be 10 k ohms. If out of range then it would need to be replaced. If this checks ok and the thermostat and heater have continuity then the control board would need to be replaced.
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.
