What AF means
For a Kenmore electronic-control dryer numbered 110 (Whirlpool-built), AF means restricted airflow, also shown as F4 E3. Air is not leaving the dryer freely, usually because the lint screen or the vent is clogged, crushed or kinked, or the duct run has too many turns. The dryer keeps running while AF shows, but loads take longer and the cabinet runs hotter. This reading comes from Whirlpool's documentation for the platform, not from the Kenmore 110 manual we checked.
Common causes of AF
- Lint screen coated or clogged
- Vent run crushed, kinked or too long
- Too many elbows in the duct
- Blocked exterior vent hood
1. Touch any key to clear the AF display. 2. Clean the lint screen and wash off any film left by dryer sheets. 3. Check the vent run behind the dryer for crushing or kinks. 4. Check the exterior hood flap opens freely. 5. Check the run length and number of elbows, then run a Timed Dry heated cycle.
- The code names the airflow path and not the exact spot where it is blocked.
- We inspect the whole run from the dryer to the hood.
- The price is in writing before work, and a 30-day warranty applies to repairs.
Other Dryer codes
Why is AF showing on my Kenmore dryer?
Air is not moving freely out of a 110-series, Whirlpool-built dryer. Look at the lint screen, the vent run behind the dryer and the outside hood, in that order. A quick look at each saves a service call more often than you would expect.
Where does F4 E3 fit in?
Yes. AF and F4 E3 describe the same restricted airflow condition on this platform, so whichever one your display shows, the same checks apply. Fixing the airflow is usually the whole cure.
Can I keep drying clothes?
The dryer keeps running, but a blocked vent traps heat and lint. Clear it soon instead of ignoring it, since drying time and cabinet temperature both climb.
