How to Fix / Troubleshooting
Safety first: Unplug and allow the unit to cool before inspection.
- Clear airflow: Ensure all air intake and exhaust vents are free of dust and obstructions. Maintain at least 6–12 inches of clearance around the unit.
- Clean internal components: For warm mist models, descale the heating chamber. For cool mist models, clean the fan area and vents with a soft brush or compressed air.
- Check fan operation: When powered on, verify that the fan starts immediately and runs smoothly. If it hesitates, squeals, or stops, the fan motor may be failing.
- Replace thermostat: If the unit still overheats and cycles off quickly, the overheat thermostat may be weak and should be replaced with the correct temperature-rated part.
