Quick answer
Whirlpool's opened Product Help page groups F10 through F24 under Compact Heat Pump Dryer and says to turn the dryer off, unplug it for about 30 minutes, then restart once; if the failure persists, call for service. That instruction is explicitly platform-scoped and is not a universal Whirlpool dryer reset. Whirlpool's general dryer error page says an alternating F# E# display requires service and directs owners to the exact Owner's Manual. With the model, market, and complete display missing, first record the exact message and full model, then apply the 30-minute step only if the matching compact heat-pump documentation confirms it. Do not import F24 from a Whirlpool washer, dishwasher, or another dryer, and do not open the cabinet, enter diagnostics, test live wiring, or guess a thermistor, control, or other part.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
With the dryer stopped and cool, photograph or transcribe every display character exactly, including whether it reads F24, F-24, alternates between F and 24, shows F2 E4, or includes another message or flashing indicator. Do not restart it merely to reproduce the display.
Expected result: The message is exact standalone F24, an alternating F# E# pair, a different code, or cannot be read reliably.
Next step: Keep the exact image or transcription for the service request and compare it only with the manual for the complete dryer identity.
Stop if: Do not enter diagnostics, repeatedly reset the dryer, or run cycles to force a different code.
Why this matters
Why: Whirlpool treats an alternating F# E# display as a service condition, while its compact heat-pump page groups F10–F24. Dropped punctuation or digits can change the applicable branch.
-
Check 2
Read the complete Whirlpool dryer model number from its ordinary name plate without removing panels or moving the appliance, and record the purchase country or market and whether the dryer is a compact heat-pump design.
Expected result: The full model confirms a compact heat-pump dryer, a different dryer configuration, only a partial model is available, or the market remains unknown.
Next step: Use the full model number in Whirlpool's manuals and literature lookup, then match the code and configuration before any reset.
Stop if: Do not use a compact heat-pump instruction on a vented, gas, traditional, washer-dryer, or different-market appliance without matching documentation.
Why this matters
Why: The opened F10–F24 instruction is explicitly for a compact heat-pump platform. A partial identity cannot show whether that page, another regional manual, or a different display table applies.
-
Check 3
If and only if the matching manual confirms the compact heat-pump F10–F24 path, turn the dryer off, unplug it from a dry, safe position, wait about 30 minutes, and restore power once. Do not perform this reset when there is smoke, odor, abnormal heat, water near electrics, cord damage, or a repeated breaker trip.
Expected result: The code clears and the cycle behaves normally, the code returns, or the dryer remains unresponsive or abnormal.
Next step: If F24 returns or operation remains abnormal, keep the dryer off and arrange Whirlpool or qualified appliance service with the exact model, display, and reset result.
Stop if: Do not repeat the reset, open the cabinet, access a heater or control, or measure live voltage.
Why this matters
Why: Whirlpool documents this single power-off interval for its Compact Heat Pump Dryer F10–F24 page. A returning failure is a service condition; a clear display does not prove a part was repaired.
-
Check 4
From outside the appliance, check for smoke, burning or melting odor, arcing, unusual heat, a hot or damaged cord, water near electrical parts, or a breaker that trips again. Do not energize the dryer when any of these signs are present.
Expected result: The dryer is cool and dry with no hazard, or a leak, wet electrical area, odor, smoke, arcing, heat, damage, or repeated trip is present.
Next step: For a nonhazardous recurring or unmatched F24, leave the dryer off and arrange qualified service. For a hazard, isolate the appliance and obtain urgent qualified appliance or electrical help.
Stop if: Do not repeatedly reset a tripping circuit, run a heat cycle to test it, or open the rear, top, heater, or control enclosure.
Why this matters
Why: A safety symptom overrides code interpretation and makes powered testing inappropriate. A dry exterior still does not justify selecting a part from an unmatched F24.

Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
The exact model confirms a Whirlpool compact heat-pump dryer, the full display is F24 within the F10–F24 group, and no safety hazard is present.
Do this next
Follow that matching manual's single power-off/unplug step and arrange service if F24 returns; do not infer a board, sensor, or other part.
Why this path and its safety boundary
Why it matters: The opened Whirlpool Product Help instruction is applicable: one safe power-off interval is documented, followed by service if the failure persists.
-
PATH 02Next step
What you see
F24 is displayed but the dryer is not confirmed as a compact heat-pump model, the model is partial, or the purchase market cannot be identified.
Do this next
Use the full name-plate model and market in Whirlpool's manual lookup and give the exact display to qualified service; do not apply the 30-minute instruction until the platform matches.
Why this path and its safety boundary
Why it matters: The compact heat-pump page is not proven applicable. The safe conclusion is an unresolved Whirlpool dryer code, not a universal reset or component diagnosis.
-
PATH 03Next step
What you see
The full display alternates between F# and E#, reads another code, or belongs to a Whirlpool washer or dishwasher rather than a dryer.
Do this next
Preserve the exact display and obtain the matching appliance manual or qualified service; do not rename the code as standalone dryer F24.
Why this path and its safety boundary
Why it matters: Whirlpool's general dryer page routes alternating F# E# displays to service, and the washer F24 page has a different meaning. Cross-platform code migration would select the wrong repair path.
-
PATH 04Next step
What you see
F24 is accompanied by smoke, burning or melting odor, arcing, unusual heat, cord damage, water near electrical parts, or repeated breaker trips.
Do this next
Leave the dryer off, keep clear of damaged or wet electrical areas, and obtain urgent qualified appliance or electrical help.
Why this path and its safety boundary
Why it matters: The safety condition overrides code interpretation and makes further operation inappropriate.
Helpful context
Understand the symptom
What Whirlpool's opened dryer sources actually establish
Whirlpool Product Help has a page titled F10 to F24 - Compact Heat Pump Dryer. It tells that platform's owner to turn the dryer off, unplug it, wait about half an hour, and restart the cycle; if the failure returns, service is required. A Whirlpool manufacturer PDF for a particular dryer literature set also groups F10–F24 and gives the same 30-minute boundary, while warning that display format can vary by model. These sources support a conditional compact-heat-pump path, not a diagnosis for an unspecified Whirlpool dryer.
Why F24 cannot be borrowed from another appliance
Whirlpool's general dryer error page describes AF/F4E3, L2, PF, and alternating F# E# displays, but it does not define a universal standalone F24. Whirlpool also publishes F24 guidance for compact front-load washers, where the decision is different. Therefore the first useful check is the appliance platform and full display: a washer F24, a dryer F24, and an alternating F2 E4 display are not interchangeable. Whirlpool's manuals page requires the model number to retrieve the matching literature.
When checks do not resolve it
Need a professional?
Arrange Whirlpool or qualified appliance service for an unmatched model or market, a non-compact dryer with F24, an alternating F# E# display, or F24 that returns after the one model-approved compact heat-pump reset. Do not choose a thermistor, control, wiring, heater, or other part from F24 alone. For smoke, burning or melting odor, arcing, unusual heat, cord damage, water near electrical parts, or repeated breaker trips, leave the dryer off and seek urgent qualified appliance or electrical help.
