How to Fix / Troubleshooting
Safety first: Unplug and cool before inspection.
Steps:
- Ventilation: Ensure adequate space around the unit to prevent overheating.
- Internal wiring: Open the housing and check all push-on connectors and screw terminals for tightness.
- Solder joints: Inspect the main board for dull or cracked solder joints, especially at high-current points (heater relay, mains input). Reflow if necessary.
- Thermal cut-out: Test the thermostat/thermal cut-out for correct operation; replace if it opens at too low a temperature.
Warning: Intermittent faults can be difficult to trace; if unsure, consult a professional.
