Whirlpool Dryer Error Codes
AF, L2, F01, F22, F24 — What They Mean & How We Fix Them
Whirlpool, Maytag, KitchenAid, Kenmore Elite and Amana dryers share most fault codes, including the Cabrio, Bravos, Oasis and Duet models. The ones to know are AF (airflow restriction, so the dryer is telling you the vent needs cleaning), L2 (low line voltage, often a half-tripped breaker), F01 (main control) and F22 / F24 (temperature sensor faults).

Whirlpool Dryer Error Code Repair — Twin Cities — Quick Answer

The Twin Cities repair mix
Whirlpool dryer diagnostic mode
Diagnostic mode differs by model: many dryers use a cycle-knob sequence, and some Duet front-loaders use a button pattern. The sequence also changes between generations, so check your manual or the label on the dryer rather than a generic combination. Diagnostics step through the heater, motor, sensor and door switch tests and show stored codes afterward.
Most common Whirlpool dryer error codes
AF — Airflow restriction: the dryer measured that air isn't leaving fast enough, so clean the lint screen and the whole vent run to the outside cap. | L2 — Low or no line voltage on one leg of the 240V supply: usually a half-tripped breaker. Flip the breaker fully off, then back on; if L2 returns, the outlet or supply needs an electrician. | PF — Power failure during the cycle: press Start to resume. | F01 — Main control fault ($385–$525). | F22 / F23 — Outlet (exhaust) temperature sensor open or shorted ($225–$285). | F24 — Inlet temperature sensor fault ($225–$285). Other F-codes vary by model, so call with the exact display and your model number.
AF means clean the vent
Whirlpool and Maytag dryers watch airflow and temperature, and show AF when the vent looks restricted, which can happen before the high-limit thermal fuse trips. Clean the vent run from the dryer outlet to the exterior cap before replacing any parts. Ignoring AF lets the dryer overheat, which can blow the thermal fuse and stress the heating element, so the repair gets larger. Test both parts if the dryer stops heating.
Cabrio, Bravos, Oasis and Duet dryers
Cabrio, Bravos and Oasis dryers use the same platform as other Whirlpool and Maytag dryers, so the codes above apply to them too. Display wording differs a little between generations, so match the idea as well as the exact letters, and confirm with your model number.

FAQ
Dryer repair in the Twin Cities: FAQs
What does AF mean on a Whirlpool dryer?
AF means the dryer detected an airflow restriction, so the vent needs cleaning. Clean the lint screen and the vent run from the dryer outlet to the exterior cap. Ignoring it lets the dryer overheat, which can blow the thermal fuse and stress the heating element.
What does L2 mean on a Whirlpool dryer?
L2 means low or no line voltage on one of the 240V legs. A half-tripped breaker is a common cause, since the breaker can look on while one leg has tripped. Switch the breaker fully off, then back on. If L2 returns, the outlet or supply wiring needs an electrician.
What does F22 or F24 mean on a Whirlpool dryer?
F22 is the outlet (exhaust) temperature sensor reading open, and F24 is the inlet temperature sensor. These are inexpensive sensor swaps, $225–$285 all-in. They are often paired with a vent inspection, since heat from a restricted vent can shorten sensor life.
How do I enter Whirlpool dryer diagnostic mode?
It differs by model. Many dryers use a cycle-knob sequence and some Duet front-loaders use a button pattern, so check your manual or the label on the dryer. If you can't find it, note the code and call with your model number.
Does a Cabrio or Bravos dryer use the same codes?
Yes, Cabrio, Bravos and Oasis dryers use the same Whirlpool platform, so AF, L2, F01, F22 and F24 mean the same thing. Display wording can differ a little between generations, so we confirm with your model number.
How much does Whirlpool dryer repair cost?
Most Whirlpool dryer repairs land $245–$485 all-in. Thermistor $225–$285. Door switch $225–$345. Heater plus thermal fuse $345–$485. Gas valve coils $245–$345. Main control board $385–$525. The $149 trip fee is credited toward the repair when you approve it.
Are Whirlpool, Maytag, and Kenmore dryer codes the same?
Often, yes. Whirlpool, Maytag, KitchenAid, Kenmore Elite and Amana dryers share control platforms, so codes such as AF, L2, F01, F22 and F24 and many internal parts are cross-compatible. Confirm with your model number.

Whirlpool dryer codes: meaning and what we check
These are the codes we are confident about on Whirlpool-built dryers. Display wording differs a little between generations, so match the idea, not only the exact letters.
| Code | What it means | What we check |
|---|---|---|
| AF | Airflow is restricted; the dryer is warning you about the vent | Lint screen, the whole vent run from the dryer to the outside cap, crushed foil or vinyl duct |
| PF | A power failure happened during the cycle | Nothing in most cases; press Start to resume. If it repeats, the outlet, breaker and cord |
| F01 | Fault in the main electronic control | Power at the board first, then connectors, then the board itself |
| F22 | Exhaust (outlet) temperature sensor reads open (F23 is shorted) | Thermistor resistance and its connector |
| F24 | Inlet temperature sensor reads open or shorted | Thermistor resistance and its connector |
Prices from this page: thermistor repairs $225 to $285 all-in, most Whirlpool dryer repairs $245 to $485. The $149 trip fee is credited toward the repair when you approve it.
Does AF mean my Whirlpool dryer is broken?
No. AF means the dryer cannot push air out as fast as it expects, so it is warning you about the vent. That is useful, because a dryer with poor airflow overheats, and overheating is what eventually trips the thermal fuse and burns out the heating element. Treat AF as a maintenance message.
Start with the lint screen: pull it, look for a film on the mesh and wash it with warm water and a soft brush if water does not pass through it. Then slide the dryer out, disconnect the duct and check the transition piece behind it, which is the flexible duct most likely to be crushed. Look at the outside cap for lint, snow or a stuck flap. In a Minnesota winter, a flap held shut by ice or a bird nest is common.
If the vent is clear and AF stays, the next suspect is a sensor reading wrong. We measure the temperature sensors and confirm airflow at the exit before replacing anything. Our dryer repair page covers vent checks and our vent cleaning add-on.
What should I do when a Whirlpool dryer shows an F code?
Write the code down, unplug the dryer for a minute, plug it back in and run a short timed cycle. A code that does not come back was a glitch. A code that returns points at the part named in the table.
Take care with one safety point: if the code appears and the dryer is also very hot, smells of burning or has stopped mid-cycle with damp clothes, do not keep running it. Unplug it and call. For a gas dryer, a gas smell means leave the house and call the gas utility; do not touch the gas supply yourself.
Sensor codes like F22 and F24 are among the cheaper repairs, but they are often a symptom of heat soak from a restricted vent, so a good repair includes a vent check. See dryer not heating if the dryer runs but the clothes stay damp.
Do Maytag and Kenmore dryers use the same Whirlpool codes?
Often, yes. Whirlpool builds many dryers sold under other names, and the control logic and a lot of the parts are shared. Central Minnesota Appliance Repair services these dryers across Minneapolis, St. Paul and the surrounding metro. Model-specific differences exist, so we confirm against the model tag. We also cover Maytag dryer repair and Whirlpool dryer repair separately.
More questions about Whirlpool dryer codes
Can I keep using my dryer when AF is showing?
For a short time, yes, but each load takes longer and runs hotter. Clean the lint screen and check the vent soon, because continued overheating is how thermal fuses and heating elements fail.
Why does my Whirlpool dryer show PF after a storm?
PF records that power dropped during the cycle. Press Start to resume. It is not a fault unless it appears without an outage, in which case the outlet, breaker or cord is worth checking.
Should I reset a dryer with an F01 code?
You can unplug it for a minute and try once. If F01 returns, do not keep power-cycling. A control fault can be caused by a failed part elsewhere, and we test before replacing the board.
How often should I clean my dryer vent?
Once a year is a sensible starting point for a typical household, and sooner if the vent is long, has several bends or runs through a cold space. Clean it earlier if drying times grow.
