Why is my LG D12RX not cooling properly?
Check if the filter is dirty, the thermostat is set correctly, and the outdoor unit has clearance. Also ensure the room is not too large for the unit (max 30 m²). If problem persists, contact LG Service.

Press the TIMER button on the remote. Use the + or - buttons to set the On or Off time. Press TIMER again to confirm. The display will show the set time.

Can I use the LG D12RX in winter for heating?

Clean the filter every 2 weeks. Schedule professional maintenance once a year to check refrigerant levels, clean coils, and ensure safe operation.
Why does my LG D12RX make a clicking noise?
Clicking sounds are normal when the compressor starts or stops, or when the plastic expands/contracts with temperature. If loud or continuous, inspect for loose parts or contact LG Service.
