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

Improve ventilation: Move the unit away from walls and heat sources. Ensure at least the manufacturer‑recommended clearance on all sides.
Clean condenser: Remove dust and lint from the rear condenser coil and grille.
Verify fan operation: Confirm that the fan runs whenever the compressor is commanded on. Replace the fan motor if it does not.
