Use this guide to test the moisture sensor on your Whirlpool Dryer and replace it if necessary.

The moisture sensor checks the moisture content of the laundry by measuring the resistance between two metal strips when the clothing touches them during drum rotations. As the clothing dries, the resistance goes up.

If the moisture sensor fails on auto dry settings, especially with an open circuit between the strip and the connector, the dryer will not heat. If the moisture sensor fails with a short circuit between the two strips, the dryer may cycle its heat until the max cycle time is reached. It may also give an error code. This can waste a lot of energy.

This repair is rated difficult because of the amount of disassembly needed. Some of the steps are difficult, especially removing and reassembling the front bulkhead.

***This guide will work for most Whirlpool dryers.*** This guide is written with a model WED87HED dryer. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same.
