Why is my Daewoo DSB-125LH not cooling well?
- E
  ernest31Aug 5, 2025
  If your Daewoo Air Conditioner isn't cooling the room effectively despite airflow, several factors could be at play. First, check the temperature setting to ensure it's appropriately set. Also, a blocked air filter can reduce cooling efficiency, so clean the air filter. Open doors or windows can also impact cooling performance, so close them. Make sure that neither the air inlet nor the outlet of the indoor or outdoor unit is blocked by any obstructions. Clear any obstructions and restart the unit. Finally, the compressor might be under a 3-minute protection mode; simply wait for it to complete its cycle.

  If your Daewoo Air Conditioner fails to start, there are several potential causes. Initially, check for a power outage and wait for the power to be restored. Ensure the unit is securely plugged into the wall receptacle. Inspect the fuse and replace it if it has blown. Also, verify the batteries in the remote controller and replace them if exhausted. Finally, the timer setting may be incorrectly set; wait or cancel the timer setting.
