Is your daikin air conditioner not working properly? Don’t panic—many issues can be solved with simple checks before calling in a technician. Below are some of the most common problems and how you can approach them.

AC Not Cooling

If the unit isn’t cooling the room, make sure all doors and windows are closed so cool air isn’t escaping. Double-check the remote settings to confirm it’s on cooling mode (snowflake icon) and set the temperature to 24°C or lower. Also, check the filters. Dust buildup restricts airflow, so cleaning them every four weeks can make a big difference.

Water Leakage

Excess water may result from dirty filters or a damaged drain pan. Start by cleaning the filters. If the leak persists, professional inspection is the safest choice.

Bad Odors

A slight odor right after switching on can come from the Streamer purification feature. However, if the smell lingers, worsens, or seems like burning, turn the unit off immediately and seek expert help.

Remote Control Problems

When the daikin remote doesn’t work, try replacing the batteries. If that fails, reset it by holding the power button for two seconds, then pressing again to restart.

Unit Not Responding to Remote

Check for battery issues, reset the remote, or reset the entire system. Ensure nothing blocks the unit’s sensor.

Short Cycling

If your AC keeps shutting down quickly, it could be due to clogged filters, dirty condenser coils, or low refrigerant levels. The last two issues require a technician.

Heat Pump Troubleshooting

In summer, clogged filters or dirty coils are common culprits. In colder months, sensors, valves, or leaks may be the problem. These situations usually call for professional repair.

Regular maintenance and quick checks can solve minor issues, but for complex problems, it’s always safer to rely on qualified technicians.
