  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.

  If your DeLonghi Air Conditioner isn't turning on, there could be a few reasons. First, make sure it's properly plugged into the outlet. If it is, check if there's a power outage and wait for the power to return. If neither of these is the issue, the internal safety device may have tripped, in which case you should call the Service Center.

  If your DeLonghi Air Conditioner only works for a short period, it might be due to a kinked air exhaust hose. Ensure the hose is positioned correctly, keeping it as short and free of curves as possible. Also, check for and remove any obstructions blocking air discharge.

  If your DeLonghi Air Conditioner doesn't start immediately after restarting, it's likely due to an internal safety device. This device prevents the unit from restarting for about three minutes after it was last turned off. This delay is normal.
