Haier Dryer Error F4
⚡ Quick Answer: The Haier dryer F4 error code indicates a malfunction related to the temperature sensor, leading to improper heating and inconsistent drum temperature... ✅ DIY Fixable
What Does Error F4 Mean?
The Haier dryer F4 error code indicates a malfunction related to the temperature sensor, leading to improper heating and inconsistent drum temperatures. Symptoms include failure to heat, early cessation of drying cycles, and the F4 error displayed on the control panel. This issue can stem from a faulty temperature sensor, heating circuit component failure, or a humidity sensor reporting inaccurate data.
Common Symptoms:
- Dryer fails to heat
- Drying cycle stops early or is ineffective
- Error F4 displayed on control panel indicating a heating‑related fault
Possible Causes
- Temperature sensor (heater or condenser) fault (medium)
- Heating circuit component failure (heater element / thermostat / heater relay / control triac) (medium)
- Humidity sensor reporting inconsistent data (possible false trigger) (low)
How to Fix Error F4
DIY Fix Basic checks and reset
- Turn off and unplug the dryer for at least 5 minutes to reset memory.
- Ensure lint filter, condenser and airflow paths are clean and not obstructed.
- Verify the dryer isn’t overloaded and the door is fully closed before restarting.
Technician Only Diagnose and repair heating circuit and sensors
- Visually inspect and test temperature sensors (heater thermistor / condenser sensor) for correct resistance and operation with a multimeter.
- Check heater element, thermostats, and associated relays / control triac for continuity or signs of damage.
- Replace any failed heating circuit components and verify control board functionality.
- After repairs, test the dryer through multiple cycles to ensure F4 no longer appears.
Parts needed: Temperature sensors (heater / condenser), Heating element, Thermostats / heater relay / triac, Control board (if component failures are on board)
- If the F4 error persists after cleaning filters and resetting power
- If you are not comfortable performing electrical diagnostics
- If parts show signs of burn damage or sensors fail basic continuity tests
