Introduction
Use this guide to replace the refrigerator thermistor or temperature sensor in your Whirlpool WRS315SDHW Refrigerator.
The refrigerator thermistor measures the air temperature in your refrigerator and signals temperature regulatory processes. If your refrigerator doesn't cool properly, your refrigerator thermistor might be broken.
To replace the freezer 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.
