Amana Dryer F12 Error Code

The moisture sensor bars (two metal strips) are not detecting wetness, causing auto-dry cycles to malfunction.

Common causes

How to fix it

  1. Clean the sensor bars (two metal strips inside the drum near the lint screen) with a damp cloth or fine sandpaper.
  2. Ensure wiring to sensor is connected.
  3. Run a timed dry cycle to bypass sensor.
⚠ When to call a pro: If cleaning does not resolve, the sensor or control board may need replacement — call a technician.
