Whirlpool Refrigerator Freezer Thermistor Replacement

Use this guide to replace the freezer thermistor or temperature sensor in your Whirlpool Refrigerator.

The freezer thermistor measures the air temperature in your freezer and signals temperature regulatory processes. If your freezer doesn't cool properly, your freezer thermistor might be broken.

This guide will work for most Whirlpool refrigerators. This guide is written with a model WRS315SDHW refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.

To replace the refrigerator thermistor, follow this guide instead.

Note: Some photos show the doors removed for clarity purposes. Removing them is not required and will not change the procedure.
