Why did my Whirlpool refrigerator stop working?
Dirty condenser coils are the most common cause for a Whirlpool refrigerator not cooling. Condenser coils dissipate heat as the refrigerant passes through them. If the coils are clogged in dirt and debris, they can’t release the heat properly.
What is the purpose of heating element?
What is a heating element? A heating element converts electrical energy into heat through the process of resistive (otherwise known as Joule heating). The electric current passing through the element encounters resistance, which produces heat.
What is defrost heater in refrigerator?
The defrost system activates a defrost heater in the evaporator section at the rear of the freezer. This heater melts frost off of the evaporator coils and then turns off. When the defrost heater is on, it is normal to see a red, yellow or orange glow from the freezer.

Defrost timers almost always have four metallic terminals extending from the bottom. Remove the timer once you have located it.
How does refrigerator heater work?
A temperature sensor Every six hours or so, the timer turns on the heating coil. The heating coil is wrapped among the freezer coils. The heater melts the ice off the coils. When all of the ice is gone, the temperature sensor senses the temperature rising above 32 degrees F (0 degrees C) and turns off the heater.
