Verify that the air filter is clean and not obstructed. Ensure the ambient temperature and humidity are within the unit's operating range (e.g., above 41°F / 5°C). Check if the continuous drain hose is properly connected and not kinked or blocked. - Unit is making unusual noise:
Ensure the unit is placed on a stable, level surface. Check for any loose parts or obstructions in the air intake or exhaust vents. - Water is leaking from the unit:
