# Whirlpool-built Kenmore dryer error code AF

### Whose code this actually is

Kenmore did not write AF, because Kenmore has never built an appliance. This one is Whirlpool’s, and it appears on the dryer that Whirlpool built and Sears sold under the Kenmore badge. Whirlpool, LG and Frigidaire all built dryers for this badge, and all three publish short two-character codes, so a lookup that skips the prefix is a coin toss dressed as an answer.

### What it means

Restricted air flow. Whirlpool's own wording names a clogged lint screen or vent, and it is the single most common code on a dryer in this part of the world.

### Which Kenmore models can raise it

The Kenmore dryer whose model number begins 110 — the three digits before the period on the rating plate. Those digits are Whirlpool’s, which is why Whirlpool’s table is the one that applies to AF and no other manufacturer’s does.

### The other ways it may be written

The same condition is published under more than one label, because it has been carried across generations of the appliance and because a segment display draws some characters oddly: **Check Vent, F4 E3**. They are the same finding and they lead to the same place.

### Worth trying yourself, in this order

- Clean the lint screen every load, and wash it if fabric softener has glazed it.
- Check for airflow at the outside hood with the dryer running. If you cannot feel any, the duct is the repair.
- A crushed flexible duct behind a dryer pushed back to the wall does this on its own.

### Where this usually goes

The job this most often becomes is [dryer vent cleaning](/services/dryer-vent-cleaning/), and that page carries a starting figure and the reasons that move it. A Kenmore dryer in South Florida is almost always on a long horizontal duct carrying humid air, and that duct is behind more heat and airflow codes here than any component inside the machine. Photograph the display before you cut the power: a reset clears AF, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis.

### Where this meaning came from

Whirlpool’s own documentation: *Dryer error codes — Whirlpool Product Help*. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer’s document instead.
