The W11438736 Genuine OEM Whirlpool Refrigerator Thermistor is an original manufacturer temperature sensor designed for compatible Whirlpool refrigerators and select brands manufactured by Whirlpool, including Maytag, Amana, KitchenAid, Jenn-Air, and others. This genuine OEM thermistor continuously monitors internal refrigerator temperatures and sends readings to the electronic control board, allowing the appliance to maintain proper cooling performance and food preservation. Available from Appliance Kingdom with fast Canada-wide shipping, this part is commonly used to resolve temperature regulation issues, freezing problems, and inconsistent cooling performance.

What Does the Refrigerator Thermistor Do?

The thermistor is a critical temperature-sensing component inside the refrigerator. It measures air temperature and communicates that information to the control board, which then adjusts compressor and evaporator fan operation to maintain the correct temperature. When the thermistor provides inaccurate readings, the refrigerator may cool excessively, fail to cool properly, or run longer than necessary. Genuine OEM specifications are important because even small temperature-sensing inaccuracies can affect food storage conditions, energy efficiency, and overall appliance performance.

Common Symptoms Indicating Thermistor Replacement

A faulty thermistor can cause a variety of refrigerator performance issues, including:

• Refrigerator section freezing food
• Refrigerator running too cold
• Refrigerator compartment too warm
• Inconsistent temperatures throughout the refrigerator
• Excessive frost or ice buildup
• Refrigerator running continuously
• Freezer cold but refrigerator section warm
• Defrost performance issues
• Temperature fluctuations despite control setting adjustments

Replacing a defective thermistor often restores accurate temperature control when the sensor has failed or is providing incorrect resistance readings. However, similar symptoms may also be caused by control boards, wiring issues, fans, or defrost system components. Proper diagnosis is recommended before replacement.
