Customer Questions and Answers for Thermistor by Whirlpool

The Thermistor is an OEM replacement part for Whirlpool refrigerators. This temperature-sensitive sensor monitors conditions inside refrigerator and freezer compartments. It provides critical feedback to the electronic control module, regulating cool air temperature in both sections.

Symptoms of a faulty thermistor include:

• Fluctuating temperatures where sections become too warm or cold  
• Frequent cycling of evaporator fans and cooling components
• Defrost issues or Er/Ed error codes shown on displays

Causes can involve regular exposure to changing interior environments over many years. Mineral deposits accumulating may lead to sensor surfaces becoming insulated. Physical stress from overloading could potentially crack the thermistor over time as well. 

This OEM replacement part is compatible with some Kenmore Elite models too.
