WP2188820 - Whirlpool Refrigerator Temperature Sensor

This Refrigerator Temperature Sensor (WP2188820) is a genuine part designed for Whirlpool refrigerators, compatible with KitchenAid, Jenn-Air, Thermador, and Maytag brands as well. Functioning as a thermostat or thermistor, also known as a "temperature-dependent resistor," this sensor is critical in maintaining your refrigerator's desired temperature. It is strategically placed within the unit to accurately measure the ambient temperature and signal the control circuit. Changes in resistance, caused by temperature fluctuations, are interpreted by the control circuit, converting them into temperature readings. When the internal temperature diverges from the preset target, the circuit prompts the cooling system to activate, ensuring foods are stored under optimal conditions to minimize spoilage and extend shelf life. Regular cleaning, calibration, and potential replacement of the temperature sensor are essential steps to maintain your refrigerator's performance.

If your refrigerator experiences erratic temperature control, uneven cooling, or the compressor cycles on and off too frequently, it may be indicators that the temperature sensor is failing. Before considering a replacement, verify that this part (WP2188820) is compatible with your refrigerator's model number.
