Defrost Timer - 60Hz 120V

Defrost timers are part of the defrost circuit in your refrigerator and freezer. This timer cycles the defrost heater on and off. For every eight hours, the appliance timer will cycle for 30 minutes. The defrost heater is what melts the frost buildup on the evaporator coils, and it can prevent your freezer from frosting up. If your timer fails, the heater will not get the energy it needs to run, and frost will continue to build up. Test the defrost thermostat and the defrost heater with a multi-meter. If they are in working order it is likely that the defrost timer is the faulty component of the circuit and needs to be replaced. Before you begin this repair make sure the appliance has been unplugged.

It took longer to remove the retainer bar from the packaging than it did to install it in the fridge.

Both left and right end caps were pushed into their respective places on the retainer bar and then the whole thing was snapped into place on the door of the fridge.

Put them together and (do this carefully, as they are light-duty plastic; the reason the originals failed) snapped them into place. Parts were factory-origninal, easy to figure out. Delivery time was exceptional, packaging great. read more
