Why is my DeLonghi Arctic Whisper PAC EL290HLWKC Air Conditioner running but not cooling the room?
- LLeslie SmithAug 10, 2025
Several factors can cause your DeLonghi Air Conditioner to run without effectively cooling the room. Check for these potential issues: * Ensure windows, doors, and drapes are closed to keep cool air in. * Eliminate any heat sources in the room, such as ovens or hair dryers. * Verify the air exhaust hose is correctly attached to the back of the unit. * Clean or replace clogged dust filters. * Consider that the unit's cooling capacity may not be suitable for the room size.
