Possible Causes
Overheating of control board area, Failing mains filter or power relay, Loose mains connection inside dryer, Overheating causing internal thermal fuse to open intermittently
How to Fix / Troubleshooting
Safety first: Unplug the dryer and allow it to cool before inspection. High temperatures may be present near the heater and control board.
- Check ventilation: Ensure the dryer is not installed in a confined space without adequate airflow.
- Inspect mains connections: Remove the top cover and check the terminal block, mains filter, and wiring for loose screws or discolored connectors. Tighten and replace as needed.
- Examine control board area: Look for signs of heat damage around the control board. Ensure that any cooling vents are not blocked by lint.
- Test thermal devices: If the model uses a thermal fuse or cut-out in the power path, test it for intermittent operation and replace if unreliable.
- Monitor operation: After cleaning and tightening connections, run a test cycle and monitor for recurrence. Persistent issues may require control board replacement.
