Whirlpool Dryer Error Codes
Whirlpool dryer codes include F01 control faults, F22 exhaust thermistor errors, and AF airflow restriction warnings on vented models.
General troubleshooting
Try these checks before opening a specific error code page—they resolve many Whirlpool dryer faults without parts.
- 1Clean lint screen and wash with warm soapy water if fabric softener residue builds up
- 2Measure vent run length—Whirlpool recommends professional cleaning if over 25 feet equivalent
- 3Verify the exterior vent hood flap opens fully during operation
- 4On gas units, confirm the shutoff valve is fully open and the line is not kinked
- 5Run a timed high-heat cycle with three wet towels to test heat and airflow together
Common symptoms
Owners often search for a code after noticing one of these issues on their Whirlpool dryer:
- AF or lint screen message after every load (restricted vent)
- Clothes hot but still damp at cycle end
- F22 or F24 thermistor faults on electric models
- Gas dryer ignites then shuts off within seconds
- Drum not turning with drive belt or motor-related codes
All Whirlpool dryer error codes
| Code | What it means | Guide |
|---|---|---|
| F01 | Main electronic control board failureF01 means the dryer's main electronic control board failed its self-check or stopped responding. On Duet HE models the board manages heat, motor, and moisture sensing—when it faults, the dryer may not start or may stop mid-cycle. | View fix → |
| F22 | Outlet exhaust thermistor open circuitF22 means the exhaust outlet thermistor on the blower housing reads as electrically open. The dryer cannot monitor outgoing air temperature and disables heat as a safety precaution. | View fix → |
| F23 | Outlet thermistor shorted or out of rangeF23 is the companion fault to F22—here the outlet thermistor reads shorted or below the expected resistance curve. The control treats exhaust temperature as unreliable and stops heating. | View fix → |
| F24 | Inlet thermistor open at high-limit thermostatF24 means the inlet thermistor integrated into the high-limit thermostat assembly reads open. This sensor tracks incoming air temperature before it passes the heating element. | View fix → |
| F25 | Inlet thermistor shorted at heater inletF25 reports a shorted inlet thermistor at the high-limit thermostat. The dryer interprets incoming air temperature as impossibly high or low and shuts down the heating circuit. | View fix → |
| F26 | Drive motor not responding to controlF26 means the drive motor is not operating when commanded. On Cabrio and Duet dryers the control sends run voltage to the motor but receives no confirmation of drum rotation. | View fix → |
| F28 | Moisture sensor circuit failureF28 means the moisture sensor bars inside the drum front are not returning valid readings. Auto-dry cycles that rely on conductivity across the bars cannot determine when clothes are dry. | View fix → |
| F29 | Moisture sensor shorted or low resistanceF29 is the short-circuit counterpart to F28 on Whirlpool dryers. The moisture sensor circuit reads abnormally low resistance, often from contamination or a wiring short at the drum bulkhead. | View fix → |
| F30 | Restricted exhaust airflow detectedF30 indicates restricted outlet airflow on Duet HE dryers—the blower cannot move enough air through the exhaust path. The dryer may continue running but heat cycles off early, leaving clothes damp. | View fix → |
| F31 | Low L2 line voltage below 30 voltsF31 (often paired with L2 on the display) means the second 120-volt leg of the 240-volt supply is missing or below about 30 volts. Electric dryers may tumble on one leg but cannot energize the heating element. | View fix → |
| F32 | Steam inlet thermistor circuit faultF32 appears on Whirlpool steam dryers when the steam inlet thermistor circuit reads invalid. The steam generator cannot verify inlet water temperature and disables steam cycles while the fault is active. | View fix → |
| F40 | Control board lost communication with motor boardF40 on Whirlpool Oasis and similar dryers means the main electronic control cannot communicate with the motor control board that drives the blower. The dryer may flash F40 when Start is pressed and refuse to run. | View fix → |
| F41 | Blower motor or motor control board faultF41 means the blower motor or its dedicated motor control board is not operating correctly. The dryer needs blower airflow for heat distribution—without it, the control halts the cycle. | View fix → |
| F42 | Heater state cannot be verified by motor controlF42 means the motor control unit cannot detect whether the heater is on or off through its monitoring thermistor. The dryer disables heat until the sense circuit returns valid feedback. | View fix → |
| F4E4 | Lint screen thermistor signal invalidF4E4 reports the lint screen thermistor—mounted in the lint filter housing—sent an out-of-range temperature signal. Whirlpool uses this sensor on some ventless and console models to detect restricted airflow at the filter slot. | View fix → |
| PF | Power interrupted during a cyclePF is an informational power-failure code, not a component fault. The dryer detected a loss of line voltage mid-cycle—from a tripped breaker, brief outage, or unplugging—and paused with PF on the display. | View fix → |
