Introduction
Go to step 1 ↓Use this guide to replace the defrost heater in your Whirlpool Refrigerator.
The defrost heater melts frost off the evaporator fins. If your freezer is perpetually frosty, then the defrost heater 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.
Note: Some photos show the doors removed for clarity purposes. Removing them is not required and will not change the procedure.
