Introduction
Use this guide to replace the refrigerator thermistor or temperature sensor in your Whirlpool 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.
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.
Note: Some photos show the doors removed for clarity purposes. Removing them is not required and will not change the procedure.

Great article. I have a question: My Kenmore refrigerator stopped cooling. I noticed that the compressor and fan were not operating but the evap fan was. I get no power to the compressor or fan. I replaced the start capacitor and start relay with a 3 in 1 start capacitor. Still nothing. I decided to wire the new 3 in 1 and fan with a separate AC wire directly to an outlet. This allowed the fan to start and the compressor started to cool the refrigerator. But obviously I can't use the refrig that way. Would a faulty thermistor prohibit AC from reaching the compressor and fan? I'm hoping it's not the control board. Any suggestions would be greatly appreciated. Barry
Hi Barry, your model number would be a huge help as then I can get service manuals. I'd be cautious about using a 3 in 1. Especially if your fridge was designed to use just a start relay. I think there could be an issue with the thermistor, or possibly the control board, given that the compressor ran when jumped. 3 in 1s are great to squeeze out a little more life from a compressor, but this may not be that case.
I have a Whirlpool Top Freezer Refrig Model: WRT311FZDW01 and I replaced the Control Board and the Freezer Thermistor to fix excessive wet in the Refrig section (condensation). It is now dry and cooling the Freezer well and working the Freezer as designed. However, the Refrig section does not seem to be Cold ENOUGH. I suspect the Thermistor for the Refrig (I assume there are 2 thermistors). But, I cannot find the location of the Lower/Refrig Thermistor. Is ther 2? and wher would I find the 2nd Thermistor (I suspect in the Temp Control Housing ??).
