Understanding the Problem
The moisture sensor is a set of two metal bars inside the dryer drum that detect how wet your clothes are. When it fails, auto dry cycles don't work properly — they either end too soon or run too long. The sensor bars themselves rarely fail, but the wiring connecting them to the control board can break, and the control board may not read the sensor correctly.

Helpful Repair Tip
Clean the sensor bars first with rubbing alcohol. If that doesn't help, check the wiring from the sensor bars to the control board for breaks or loose connections. You can test the sensor with a multimeter — touch both bars with a damp cloth and check for a change in resistance. If the sensor reads correctly but the dryer still misbehaves, the control board is likely the issue.
