Symptoms include the error code appearing shortly after starting a cycle, the dryer stopping mid-cycle, or issues with heating. Restricted airflow or a faulty temperature sensor may lead to this error, necessitating a thorough inspection of the airflow system and internal components.
Common Symptoms:
- Error code F1 appears on display during or shortly after cycle start
- Dryer may stop mid‑cycle
- Possible lack of heating or overheating before code appears
Possible Causes
- Over‑temperature condition detected by temperature sensor/thermistor (medium)
- Restricted airflow causing overheating (medium)
How to Fix Error F1
DIY Fix Basic Checks and Reset
- Disconnect dryer from power for a few minutes to clear transient faults
- Ensure lint filter is clean
- Check external vent for obvious obstructions
Technician Only Inspect Temperature Sensors and Airflow System
- Test thermistor/temperature sensor continuity and replace if out of spec
- Inspect and test heating element and related connectors
- Check full ventilation path for restricted airflow and clean or repair ducts and venting
Parts needed: thermistor/temperature sensor, heating element, vent/duct components
- If error persists after basic cleaning and reset
- If internal components (sensors/heater) test out of spec or are suspected faulty
