WP2188820 Whirlpool Thermistor

The Thermistor is a genuine OEM replacement part for Whirlpool refrigerators, compatible with brands such as Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. It also fits certain models from Sears-Kenmore and Ikea. This component acts as a temperature sensor, crucial for monitoring and adjusting the internal conditions of both the refrigerator and freezer compartments. It plays a key role in managing the delivery of cool air throughout the appliance.

When a thermistor begins to fail, several signs may become apparent. These include unstable temperatures within the compartments, either too hot or too cold, increased activity of evaporator fans and other cooling mechanisms, and difficulties with the defrost cycle, often indicated by error codes like Er/Ed on the display.

The deterioration of a thermistor can be due to various factors. Frequent changes in the internal environment of the appliance over several years can wear it down. Additionally, mineral buildup can insulate the surface of the sensor, impairing its function. Physical damage such as cracking might occur if the refrigerator is overloaded.

This replacement part is also suitable for some models of Kenmore Elite refrigerators.
