A Whirlpool dryer code can involve airflow, power, the control, or the door switch. Confirm letters in the exact model chart. Newer digital models spell codes on the display. Older machines may flash lights. Those patterns are not a universal chart.
How to read your Whirlpool dryer’s error codes
Whirlpool dryers don’t use one universal code system across every model. Digital Cabrio and Duet-platform dryers show a short code like AF or PF directly on the display. Older mechanical and lower-end digital models skip letter codes entirely and instead flash the cycle-status lights or the start button in a repeating pattern.
If your dryer has a screen and shows a code you don’t recognize here, check the model number on the sticker inside the door frame and search that exact model. Whirlpool changed its control-board logic across generations, so a code on a 2015 Cabrio doesn’t always mean the same thing on a current model. When in doubt, don’t guess. A wrong diagnosis wastes a part and doesn’t fix the dryer. If your dryer isn’t showing a code at all, just running poorly, our general guide to common Whirlpool dryer problems covers no-heat, noise, and won’t-start issues by symptom instead.
Before troubleshooting further, try a basic power reset. Unplug the dryer, or flip its breaker, and leave it off for a full minute. Plug it back in and start a cycle. A surprising number of codes are transient glitches from a brief power dip and clear on their own after a reset.
Common codes: AF, PF, F1, door, L2
These five letters appear on some Whirlpool digital dryers. Frequency is not ranked here. If your code is not in this list, use the model number on the sticker inside the door frame and check the fault-code chart for that model on Whirlpool’s product help site.
AF: Restricted airflow
AF is listed as restricted airflow on many Whirlpool charts. Frequency is not ranked here. The dryer’s sensors detect that exhaust air isn’t moving the way it should, which usually traces back to a clogged lint screen or a blocked exhaust vent. Pull the lint screen and clean it by hand, since a film of fabric softener residue can clog it even when it looks empty. Then check the vent line for a full clean, all the way to the exterior hood. If the exterior flap has weak airflow, mention the vent to the technician. A one-year interval is not a probability on this page. Our dryer vent safety guide covers how to check and clear it properly.
PF: Power failure interruption
Confirm PF in the exact model chart. On many charts it is associated with a mid-cycle power interruption, such as an outage, a breaker trip, or an unplug. It isn’t a hardware fault on its own. Clear it by pressing start again to resume or restart the cycle. If PF shows up repeatedly with no obvious outage, it’s worth checking whether the outlet or breaker circuit is loose or overloaded, since a flaky connection can read to the control board as a power interruption.
F1: Control board fault
Confirm F1 in the exact model chart before treating it as a control-board fault. Try the power reset first, since a board can lock up and clear with a fresh boot the same way a computer does. If F1 returns right after you start a new cycle, request a technician. A returning F1 is not a completed board diagnosis from this page. This isn’t a part most homeowners keep on hand or want to install themselves, since it means opening the control console and reconnecting a wiring harness correctly.
Door or “dor”: Door not securely latched
A door code means the switch behind the door frame isn’t sensing the door as closed, even if it looks shut. Open and firmly close the door again, and check for anything (a stray sock, a bent strike) blocking full contact. If the door clicks shut normally and the code still shows, note that for the technician. Confirm the remaining door code on the model chart. Do not name the failed part from this page.
L2: Low incoming voltage
Some Whirlpool charts list L2 as a low-voltage or missing-leg condition on electric dryers. Confirm the letters in the exact model chart. Do not treat this page as a wiring diagnosis. This points to the home’s wiring or breaker, not the dryer itself. Check that both halves of the dryer’s double-pole breaker are fully on, since one half can trip without the handle looking tripped. If both are on and the code persists, this is an electrical issue for a licensed electrician to check, not an appliance repair.
What you can reset or fix yourself
Several of these codes clear with basic homeowner maintenance, no tools beyond a vacuum and a screwdriver required.
Clean the lint screen after every load. If an AF code returns, have a technician inspect the vent run. This page does not publish a yearly success rate. If you’re not sure your vent run is clear, disconnect the exhaust duct at the back of the dryer and check for a wall of built-up lint. San Diego’s dry climate means lint doesn’t clump or smell the way it might somewhere humid, so it’s easy to underestimate how much has built up.
A PF code just needs you to restart the cycle. If it happens often, note the time of day, since a recurring PF around when other large appliances kick on (an AC compressor, a well pump) can mean the circuit is being shared and briefly sagging.
For a door code, firmly reseat the door and clear anything blocking the latch. For L2, check your breaker panel and make sure both halves of the dryer’s breaker are fully switched on.
Codes that mean a part has failed
When a code returns right after a power reset and the obvious causes are ruled out, you’re usually looking at a failed component rather than a maintenance issue.
A door code that persists after you’ve confirmed the door closes and latches cleanly can involve the door switch. Confirm the letters on the model chart. It is an inexpensive part, but it sits behind the front panel and needs the console removed to access safely.
F1 that returns immediately after a fresh reset can involve the control board rather than a glitch. Confirm F1 on the model chart. Replacing a dryer control board means disconnecting a full wiring harness and reseating it correctly on the new board, and a single misplaced connector can cause a different fault on the next power-up.
L2 that persists after confirming both breaker legs are on points to a wiring problem upstream of the dryer, which calls for an electrician rather than an appliance technician. If your dryer trips one leg of its breaker repeatedly, that’s also worth having checked before it becomes a bigger electrical problem.
Any of these part-level failures are a good time to call in dryer repair, since diagnosing a control board or door switch with a meter takes the guesswork out of which part actually failed.
San Diego Whirlpool dryer repair
The technicians in the Repair Pro San Diego network diagnose Whirlpool dryer codes and quote in writing before work begins. Coverage runs across San Diego County, from inland cities like Escondido where garage laundry rooms run hotter and dustier, to coastal cities like Carlsbad where salt air can corrode vent hardware faster than it would inland.
If a Whirlpool dryer throws a code you can’t clear yourself, we’ll match you with a technician near you. If your washer is throwing codes too, see our guide to Whirlpool washer error codes.

Frequently asked questions
What does AF mean on a Whirlpool dryer?
Confirm AF in the model chart. Restricted exhaust is one possible path the chart may name. It is not an almost-always diagnosis from this page. Clean the lint screen by hand and check the full vent run to the exterior hood. If airflow still reads as restricted after a thorough cleaning, the exhaust duct may be crushed or too long for the dryer’s blower to push air through.
How do I clear a PF code on my Whirlpool dryer?
Press start to resume or restart the cycle. PF just means the cycle was interrupted by a power loss, whether from an outage, a tripped breaker, or the dryer being unplugged. It isn’t a hardware fault, so there’s nothing to repair unless the interruptions keep happening, in which case check the outlet and breaker connection.
My older Whirlpool dryer doesn’t show a code, it just flashes a light. What does that mean?
Older Whirlpool dryers without a digital display communicate faults through a repeating flash pattern on the start button or a status light instead of a letter code. The pattern is model-specific, so check the fault-code chart in your owner’s manual, or look up your exact model number from the sticker inside the door frame to match the pattern.
Is an L2 code something I can fix myself?
Usually not beyond checking your breaker panel. Some charts list L2 as a voltage-supply fault. Confirm both halves of the double-pole breaker are on, then confirm the code in the model chart. Confirm both halves are switched fully on. If the code persists after that, it’s a wiring issue for a licensed electrician, not the dryer itself.
