Why is my Daewoo Air Conditioner not turning on?

  Angela RodriguezJul 31, 2025
  Your Daewoo Air Conditioner might not be turning on due to several reasons. It could be a power failure, so check if you can restore the power. The line voltage might be too low, in which case you should contact an electrician to install a new outlet. Ensure the unit is fully plugged in and turned on. Also, check the remote's batteries and replace them if they are weak or dead. Finally, make sure the EMERGENCY/REMOTE switch is set to REMOTE.

  If your Daewoo Air Conditioner remote isn't working, first, replace the batteries, as they may be weak or dead. Ensure you are within range of the unit. Aim the remote directly at the sensor on the air conditioner. Finally, check for and remove any obstructions between the remote and the unit.

Why does my Daewoo DSB-F154LH compressor not turn on?
- V
  vanessamartinezAug 15, 2025
  The compressor in your Daewoo Air Conditioner might not turn on immediately due to a built-in delay. When the unit is first plugged in or turned back on, there's a 3-minute delay. Also, a dirty or clogged air filter, an open door or window, an obstacle in front of the unit, or an improperly set temperature can prevent the compressor from starting. Clean or replace the filters, shut any open doors or windows, remove any obstacles, and check the temperature settings.

  Strange sounds from your Daewoo Air Conditioner, especially when turning it on or off, are usually normal. These sounds are caused by refrigerant flowing inside the unit during operation.
