Why is my DeLonghi PACEX390LVYN not cooling the room?
- KKatelyn WalkerAug 4, 2025
If your DeLonghi Air Conditioner is running but not cooling the room, several factors could be the cause. First, check that all doors, windows, and curtains are closed. Also, try to minimize heat sources in the room, such as ovens or hair dryers. Ensure the air exhaust hose is correctly attached to the back of the unit. A clogged filter can also reduce cooling efficiency, so clean or replace it as needed. Finally, the unit's specifications might not be adequate for the room size.
