Why is my DeLonghi EL275 Air Conditioner not cooling the room?
- M
  Megan PierceJul 26, 2025
  If your DeLonghi Air Conditioner isn't cooling the room, make sure windows, doors, and drapes are closed, following the recommendations for proper use. Remove any heat sources like ovens or hair dryers. Ensure the air exhaust hose is correctly attached to the back of the unit. Clean or replace clogged dust filters. It's also possible that the unit's cooling capacity isn't suitable for the room size.

  If your DeLonghi Air Conditioner does not turn on, first ensure it is properly plugged in. If it is plugged in, check if there is a power outage and wait for the power to be restored. If neither of these solutions work, the internal protection device may have been triggered, in which case you should call the help centre.

  If your DeLonghi Air Conditioner works for only a short time, check the air exhaust hose. Ensure it is correctly positioned, kept as short and straight as possible, and free from obstructions. Also, check for and remove any obstructions that are impeding air exhaust outside.

Why does my DeLonghi Air Conditioner not start immediately after restarting?
- D
  Dr. Nancy Gardner PhDAug 12, 2025
  If your DeLonghi Air Conditioner doesn't work for about 3 minutes after restarting, this is normal. To protect the compressor, an internal device delays startup for approximately 3 minutes after a restart. Please wait.
