WR9X520 - GE Refrigerator Timer

The WR9X520 (WR9X520) is a genuine part manufactured by GE for refrigerator timers. This timer is compatible with various GE refrigerator models. It's sometimes referred to as an automatic defrost timer, which is a critical component in managing the defrost cycle of your refrigerator.

The WR9X520 operates by switching power to heaters and fans in a programmed sequence to periodically defrost accumulated ice. It's a motor-driven, spring-wound, mechanical device that advances cams to open and close electrical contacts at fixed intervals and durations. This action energizes the defrost heater and terminator, ensuring efficient, automatic removal of frost from the evaporator.

If the timer fails to advance, it halts automatic defrost cycles, indicating that the part may be broken and in need of replacement. It's important to note that the specific function and location of this part may vary depending on your refrigerator model.

Before purchasing, we advise you to verify your refrigerator's model number to ensure compatibility with the WR9X520 timer.
