The Whirlpool Defrost Timer is an OEM replacement part for Whirlpool refrigerators. The defrost timer regulates the automatic defrost cycle, which prevents ice buildup on the evaporator coils in the freezer compartment by sending a signal to the defrost heater to turn on and melt any ice buildup on the coils. 

Causes of a bad defrost timer can include mechanical wear over time, electrical failures, or internal component damage. Prolonged usage and voltage spikes can also affect the timer's functionality.

Symptoms of a bad Defrost Timer include:

  • Excessive frost buildup in the freezer compartment
  • The refrigerator or freezer not maintaining the set temperatures
  • Unusual noises coming from the appliance 
  • The appliance running continuously without cycling off

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

Hello Jay, and thank you for your question. The diffuser 1126124 is a mechanical part that does not utilize electricity. As this is the case, a broken connector on the diffuser, a broken connector rod, pivot arm, or other component could be the cause of failure. Inspecting from the control knob to the diffuser would be recommended.
