Safety first: Unplug the unit and allow it to cool if it feels hot.

Check ventilation: Ensure air inlets and outlets are not blocked. Move the unit away from walls or curtains.
Verify water level: Confirm the tank is full and properly seated.
Inspect cord and plug: Look for loose connections or damage. Try a different outlet.
Reset unit: Unplug for 10 minutes, then restart.
