⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: F22 Difficulty: Moderate
Problem: The outlet temperature sensor is bad. The dryer has stopped heating for safety because it can’t read the exhaust temperature. Replace the thermistor on the blower housing.
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.
