Why is my DeLonghi EX not cooling?
- KKatelyn RhodesAug 22, 2025
If your DeLonghi Air Conditioner isn't cooling the room adequately, several factors could be at play. First, ensure all doors, windows, and curtains are closed, following the tips for correct use. Minimize the impact of heat sources like ovens or hairdryers by setting them on low or unplugging them. Check that the air exhaust hose is correctly fitted into the housing at the back of the unit. Lastly, a clogged filter can reduce cooling efficiency, so clean or replace it as described in the manual.
