  If the compressor of your Daewoo Air Conditioner doesn't turn on and there is no cool air, remember that when the unit is first plugged in, it delays turning on for 3 minutes, so wait for it to operate. The same delay occurs if the unit is turned off and immediately back on. A dirty or clogged air filter can also cause this, so clean or replace the filter(s). Ensure the unit isn't near a heat source and that doors or windows are closed. Also, remove any obstacles in front of the intake or indoor unit, and make sure the thermostat is not set too high.

  If your Daewoo Air Conditioner has no power, it might be due to a power failure; try restoring the power. The line voltage could 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, dead, or inserted improperly. Ensure you are within range of the unit and aiming the remote directly at the sensor. Also, check for and remove any obstructions between the unit and the remote.
