WR9X480 - GE Refrigerator Timer

The WR9X480 (WR9X480) is a genuine part manufactured by GE for their refrigerator models. This part is an automatic defrost timer, sometimes referred to as a defrost cycle timer or defrost control. It's crucial for the correct functioning of your GE refrigerator, especially for models designed for automatic defrosting.

The role of this timer is to control the defrost cycle in your refrigerator. It works by switching power to heaters and fans in a programmed sequence to periodically defrost accumulated ice. This is accomplished through a motor-driven, spring-wound, mechanical system that advances cams to open and close electrical contacts at fixed intervals and durations. This action energizes the defrost heater and terminator, resulting in the removal of frost from the evaporator.

If your refrigerator is experiencing issues with its defrost cycle, such as a failure to defrost or a constant running of the defrost cycle, it might be an indication that the WR9X480 timer is failing or broken. In such cases, replacing the timer might be necessary.

Before purchasing this replacement part, ensure to verify that the WR9X480 is compatible with your specific GE refrigerator model. This is important as the specific location and function of this part may vary based on the model number.
