W10822278 Refrigerator Defrost Timer110v

Technical specifications:

• Function: Control the timing of the cooling cycle and the defrosting cycle (heater operation).

• Voltage: 110-120V (suitable for common electrical systems in North America).

• Compatibility: Designed to work with selected models of refrigerators Whirlpool، KitchenAid، Maytag، وKenmore.

• mechanism: It contains a small motor and mechanical gears that open and close the electrical contacts responsible for operating the refrigeration compressor (Compressor) or the melting heater (Defrost Heater).

How to use and maintain

• Mechanism of action:

  • The timer runs the refrigerator in cooling mode for several hours.

  • It then cuts off the power to the compressor and turns on the melting heater for a specified period to melt any ice buildup on the cooling coils.

  • After the period expires, the current is returned to the compressor so that the cooling cycle continues.

• Signs of damage (when to replace?):

  1. Snow accumulation: If you notice heavy ice accumulating on the freezer coils continuously despite the refrigerator working.

  2. Cooling stopped: If the refrigerator stops cooling completely (because the timer is stuck in "melting" mode and does not switch to cooling mode).

  3. Sudden silence: If the refrigerator is completely silent and does not emit any engine sound, a timer may be to blame.

  4. Temporary test: You can try rotating the small screw on the timer face (with a hand screwdriver) clockwise until you hear a "tick" sound (Click). If the engine stops and the heater starts working, the timer will likely need to be replaced because it does not switch between modes automatically.
