Symptoms include the dryer stopping mid-cycle, failing to heat, or the drum not turning. It's essential to address these issues promptly to ensure your dryer operates efficiently.
Common Symptoms:
- Dryer stops mid‑cycle with F04 displayed
- Dryer may fail to heat properly
- Dryer may not start or drum may not turn
Possible Causes
- Temperature sensor / thermistor fault (medium)
- Inadequate power supply / line voltage issue (medium)
How to Fix Error F04
DIY Fix Basic checks before repair
- Unplug the dryer from power and wait a few minutes, then reconnect to reset electronics.
- Ensure the vent and lint filter are clean to avoid related issues.
- Verify that the circuit breaker(s) for the dryer are not tripped and that the outlet is supplying correct voltage (240 V for electric dryers).
Technician Only Inspect and test thermistor / power supply
- Disconnect power and access the temperature sensor/thermistor assembly.
- Measure the thermistor’s resistance with a multimeter across temperatures to confirm proper behavior.
- Check wiring harnesses for damage or loose connections.
- Measure actual line voltage at the dryer’s power terminals to confirm adequate supply.
- Replace the thermistor or address voltage wiring issues as required.
Parts needed: Thermistor / temperature sensor, Wiring harness, Potential power cord or terminal block parts
- If line voltage cannot be verified safely
- If thermistor testing yields inconclusive results
- If replacing sensors does not clear the code
