Whirlpool dryer error AF

What causes AF

The lint screen or the vent duct is blocked.

What to do

Clean the lint screen and check the vent hood outside. Have the duct cleaned if it is long.

Can I fix it myself?

Often, yes. Try the check below first — it costs nothing and frequently clears the code.

If the code comes back

Book a visit and add the code to the booking. A technician arrives knowing which parts to bring, diagnoses the dryer for a flat $89 and gives you an exact quote before doing any work.
