Amana Dryer F3 E1 Error Code

Because the thermistor is an internal temperature-sensing component, keep homeowner troubleshooting external. Record the code, make sure the lint screen and visible vent are not obviously blocked, then use one documented reset.

Applies to Amana dryer showing F3 E1 for an exhaust-thermistor condition

What the appliance detected

Detected condition

The dryer detected an exhaust-thermistor condition that requires model-specific diagnosis if persistent.

What may contribute

Possible causes

  • The dryer detected an abnormal exhaust-thermistor signal or related control condition.
  • Restricted external airflow can create abnormal dryer temperatures even though F3 E1 does not prove a vent problem.
  • A persistent code can require internal thermistor, wiring, connector, or control diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Check only owner-accessible airflow items

    • Clean the lint screen and look for obvious crushing or blockage in the visible transition duct before another test cycle.
    • Do not remove the dryer cabinet to reach the thermistor or wiring.

  2. Use the documented reset once

    • Switch the dryer breaker off for one minute, restore power, and run a Timed Dry cycle briefly as Amana documents.
    • If F3 E1 returns, request service instead of repeating resets.

Actions not recommended

  • Do not test resistance or voltage at the thermistor while the dryer is connected to power.
  • Do not remove panels, heater parts, or exhaust components to chase F3 E1.
  • Do not assume a new thermistor will fix the code without model-specific diagnosis.

When to stop and request service

  • F3 E1 returns after the documented reset and owner-accessible airflow checks.
  • The dryer overheats, underheats, scorches laundry, or produces a burning smell.
  • The next step requires internal thermistor, wiring, connector, or control diagnosis.
