Whirlpool Refrigerator Terminal Block, Receptacle Parts

The Defrost Thermostat and Wiring Harness is an OEM part for Whirlpool refrigerators. This part ensures that the refrigerator's evaporator coils do not become overly frosty, thereby maintaining optimal air flow and cooling efficiency throughout the unit.  

Causes for issues with the defrost thermostat and wiring harness often include electrical failures, such as short circuits or broken wires, wear and tear on the thermostat, or a malfunction that prevents it from accurately sensing temperature changes.

Symptoms of a malfunctioning Defrost Thermostat and Wiring Harness include:

• Excessive frost buildup on the evaporator coils
• The refrigerator or freezer compartment becoming too warm
• The refrigerator running continuously without cycling off
• Water leaking inside the refrigerator due to ice melting and not draining properly
