How To Fix a Dryer Moisture Sensor

Why Your Moisture Sensor Stops Working

Over time, the two metal strips inside your dryer that make up the main component of your moisture sensor may stop functioning. This is especially true if you use dryer sheets.

Dryer sheets coat everything inside your dryer, including the metal strips, with a waxy film. That prevents the strips from sensing moisture from your wet clothing. When that happens, the sensors can’t tell when the clothes are dry.

Cleaning the metal strips is quick and easy with alcohol wipes, a wire brush or fine sandpaper. Note: If you use dryer sheets, clean the moisture sensor once a month.

Locate your moisture sensor

• Look inside the dryer drum for two metal strips, about four inches long and side-by-side.
• It could be just behind the plastic housing that holds your lint filter.
• Or it could be on the back wall of the dryer drum.
