Maytag Dryer · Code AF / Check Vent / F4E3

Maytag Dryer AF code: Restricted airflow

The dryer sensed that air is not moving freely through the lint screen and vent. It keeps running, but clothes take longer to dry and lint buildup in a blocked vent is a fire risk.

Most common causes

  1. Full or coated lint screen
  2. Lint-clogged exhaust duct or outside vent hood
  3. Crushed, kinked or overly long vent run with too many elbows
  4. Outside vent flap stuck shut

What you can safely check yourself

  1. Clean the lint screen; wash it with warm soapy water if dryer sheets leave a film.
  2. Pull the dryer out and check the duct behind it for kinks or crushing.
  3. With the dryer running, check the outside vent hood for strong airflow and clear any lint or blockage.
  4. Touch any key to clear the message after fixing the vent.

Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.

Quick answers

What does AF mean on a Maytag Dryer?

The dryer sensed that air is not moving freely through the lint screen and vent. It keeps running, but clothes take longer to dry and lint buildup in a blocked vent is a fire risk.

Can I clear the AF code myself?

Try these first: Clean the lint screen; wash it with warm soapy water if dryer sheets leave a film. Pull the dryer out and check the duct behind it for kinks or crushing. With the dryer running, check the outside vent hood for strong airflow and clear any lint or blockage. Touch any key to clear the message after fixing the vent. If airflow outside is still weak after cleaning, have the full vent line professionally cleaned or a technician check the blower.
