What AF
actually means.

Maytag posts AF, also shown as "Check Vent," when its dryer detects restricted airflow. The dryer keeps tumbling while the message shows, but Maytag documents the same three checks every time: the screen, the run, and the outside hood.

What to do when AF shows on the home appliance

Kind of codeVents and airflow

Air is not moving the way the appliance expects. On a dryer that usually means lint in the screen housing, a crushed transition duct or an exhaust run packed along its length, and some makers measure it and show a code for a restricted vent before drying slows badly. On cold storage it can mean a condenser coil buried in dust or a grille blocked by a rug. Clean the screen, check the duct behind the machine with it unplugged, and book the full run cleaned; a hot or scorched smell means stop now.

Usually leads toLint path and exhaust vent cleaning

Lint cleared from the screen housing, the duct behind the laundry and the whole run to the outside hood.

Shows up asAppliance Maintenance Code or Reminder Light: Filter, Descale, Vent Check

An appliance maintenance code is a reminder, icon or short code on a display asking for a filter change, descaling, a tub clean, rinse aid or an exhaust check rather than reporting a broken part.

Maytag is a laundry name first, so a visit usually starts with the washer's hoses and cleaning cycle and the dryer's lint path, then moves to the kitchen.

Before you book,
in this order.

Each step comes from Maytag's own guidance for AF on its home appliances. Follow it to the end: the last card says whether this is a visit.

01

Clean the lint screen completely and check nothing is left caught in the mesh.

02

Check the vent run between the dryer and the wall for crushed or kinked sections.

03

Confirm the exterior vent hood outside the house is clear of lint and debris.

04

Run a Timed Dry cycle; if the message returns, book a visit to have the full vent run inspected rather than keep restarting cycles.

Still there?

It usually turns into lint path and exhaust vent cleaning. Book with the code and the model number.

What not to do

AF is an airflow alert, not a heating-element or motor code. A dryer that runs hot and shuts off early with a clear vent is pointing to a different problem that a vent cleaning will not solve.

Questions
about AF.

Can I clear AF myself?
Clean the lint screen completely and check nothing is left caught in the mesh. If it comes back, it needs a visit.
My Maytag machine keeps running with Check Vent showing — is that normal?
Yes, the dryer continues to operate with the message on screen, but Maytag documents it as an early warning that the lint screen or vent needs attention before drying times stretch out further.
I clean the lint screen every load but still get AF on my Maytag machine — what else could it be?
Look past the screen to the vent run itself: a crushed or kinked section between the dryer and the wall, or a blocked exterior hood, are the next two places Maytag points to.
Does a longer vent run make AF more likely on a Maytag machine?
It can — Maytag ties the alert to the vent meeting its recommended run length and elbow count, so an installation with too many turns or too much distance is more prone to tripping it.

Back to your everyday

Still showing AF?

A booking goes further when it has the reminder or code as shown, the model number from the rating plate, and a word on when that filter, screen or tub was last cleaned. With those three, the office can pack the right filter or cleaner for your appliance.
