Why is my Daewoo DSB-075LH not cooling well?

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.
