How to Fix F22 Error

- UNPLUG dryer from electrical power. Pull unit away from wall for rear access.
- Remove rear panel to access blower housing assembly.
- Locate exhaust thermistor mounted on blower housing near exhaust duct connection.
- Disconnect thermistor wiring harness. Note routing path before removal.
- Measure resistance across thermistor terminals with multimeter at room temperature. Should read approximately 10kΩ (±10%).
- If reading is infinite (open) or near zero (shorted), replace thermistor.
- Remove mounting screw or clip securing sensor. Gently pull thermistor from housing well.
- Install new thermistor using OEM part WPW
- Ensure sensor tip makes full contact with housing wall.
- Route wiring away from heating element and moving parts. Reconnect harness securely.
- Reinstall rear panel. Restore power. Run timed dry cycle on high heat to verify exhaust temperature readings stabilize correctly.

What to Check Next on This Whirlpool Dryer

Focused repair path: dryer airflow, heating, motor, sensor, and control checks. Do not treat this as a reset-only problem if the code keeps returning; use what the appliance does during the failed part of the cycle to choose the next check.

Disconnect power before panel inspection, then verify the lint screen, exterior vent hood, and full vent run are clear.
Confirm whether the dryer starts, tumbles, heats, and advances through the cycle; the missing function narrows the repair path.
For heat-related faults, check airflow first, then inspect the thermal fuse, thermistor, heater or gas ignition path, wiring, and control output.
For motor or control faults, listen for hums or relay clicks and inspect the belt, door switch, motor harness, and board connectors.
Order parts only after matching the complete Whirlpool dryer model number, since sensors, fuses, elements, and controls vary by platform.

Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Whirlpool model number from the appliance tag before ordering. The same error wording can use different valves, sensors, pumps, motors, heaters, locks, switches, or control boards depending on the exact model.

When It’s Better to Replace Than Repair

Dryer repairs are often worth it for small parts, but repeated heating, motor, drum, or control failures can point toward replacement.
Confirm gas vs electric, venting, voltage, doorway clearance, and laundry-space dimensions before ordering.
