Whirlpool Refrigerator thermistor / temperature sensor WP2302937, Replaces 2302937

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Refrigerator too warm or too cold
• Food freezing in the refrigerator compartment
• Refrigerator runs excessively or nearly continuously
• Temperature regulation is inconsistent
• Frost or ice buildup may occur when incorrect temperature sensing disrupts cooling or defrost control

Check Before Replacing

• Disconnect appliance power before accessing or testing the sensor.
• Inspect the thermistor connector and wiring for looseness, corrosion, or visible damage.
• With the thermistor disconnected from the control circuit, measure resistance using the appliance-specific service information.
• Compare resistance at the current sensor temperature with the applicable Whirlpool temperature-resistance chart.
• Gently change the sensor temperature and verify that its resistance changes; a fixed, open, or shorted reading may indicate a sensor or wiring problem, but does not by itself prove the thermistor is the sole cause.

Installation Notes

• Disconnect electrical power before servicing.
• Install the replacement sensor in the same location and orientation as the original so it senses the intended compartment temperature.
• Reconnect the sensor harness fully and route the wiring so it is not pinched, strained, or exposed to moving parts.
• If the sensor uses a retaining clip or holder, preserve the original mounting arrangement rather than forcing the replacement into a different position.
• Restore power and verify refrigerator temperature operation after reassembly.
