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 ?

Chuck for Model Number ZISB48DYB

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.
