WP2188820 - Genuine OEM Whirlpool Refrigerator Thermistor

WP2188820 – Genuine OEM Whirlpool Refrigerator Thermistor

The WP2188820 Genuine OEM Whirlpool Refrigerator Thermistor is an original manufacturer temperature sensor designed for use in compatible Whirlpool refrigerators and select brands manufactured by Whirlpool, including KitchenAid, Maytag, Jenn-Air, Amana, Admiral, Roper, and certain Kenmore models. This genuine OEM thermistor monitors refrigerator temperatures and communicates temperature data to the electronic control board, helping maintain consistent cooling performance and food preservation. Available from Appliance Kingdom, this part ships across Canada with fast, reliable delivery for homeowners, landlords, and appliance repair professionals.

A faulty thermistor can cause inaccurate temperature readings, resulting in cooling problems, frost buildup, freezing in the fresh food section, or excessive compressor operation. Replacing a failed thermistor with a genuine OEM part helps restore proper temperature regulation and refrigerator performance.

What Does the Refrigerator Thermistor Do?

The thermistor is a temperature-sensitive sensor that changes resistance based on the temperature inside the refrigerator. The electronic control board uses this information to determine when to run the compressor, fans, and defrost system to maintain the correct temperature.

Because the thermistor directly influences cooling operation, using a genuine OEM replacement is important for maintaining accurate temperature readings, efficient energy use, food safety, and long-term appliance reliability.

When a thermistor begins to fail, the control board may receive incorrect temperature information, leading to erratic cooling behaviour and performance issues throughout the refrigerator.

Common Symptoms Indicating Thermistor Replacement

A defective refrigerator thermistor may cause:

• Refrigerator section too warm
• Refrigerator section too cold
• Freezer section too warm
• Freezer section too cold
• Frost buildup inside the appliance
• Refrigerator running longer than normal
• Inconsistent temperature fluctuations
• Food freezing in the fresh food compartment
• Defrost system performance issues
• Poor overall cooling performance

If diagnostics identify a failed thermistor, replacing the sensor often resolves these issues. However, similar symptoms can also be caused by control boards, fans, defrost components, or sealed system problems. Proper diagnosis is recommended before replacing parts.
