Why is the compressor not turning on in my Daewoo Air Conditioner?
- A
  Amy SuttonAug 1, 2025
  If your Daewoo Air Conditioner compressor isn't turning on and you're not getting cool air, several factors could be at play. If the unit has just been plugged in or turned back on, wait 3 minutes for the compressor to engage. Check if the air filter(s) are dirty or clogged, and clean or replace them as needed. Ensure the unit isn't near a heat source like a heater or stove. Make sure no doors or windows are open, and that there are no obstacles blocking the intake or indoor unit. Finally, verify that the thermostat is set low enough.

  If your Daewoo Air Conditioner isn't powering on, there are several potential causes. First, check for a power failure and restore power if necessary. If the line voltage is too low, 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, start by replacing the batteries, ensuring they are correctly inserted. If that doesn't work, try moving closer to the unit and aiming the remote directly at the sensor. Also, check for any obstructions between the remote and the unit and remove them.
