If you are encountering performance issues with your Daikin air conditioner, there are a few options available to try and solve them. One method that works in solving a lot of issues is cleaning the air conditioner's filters. Other problems may require different solutions.

Skill level:


    Cleaning Filters

  1. 1

    Open the front panel of the indoor unit by pressing the tabs on both sides of the panel cover and lifting the cover up until you hear a clicking sound. This indicates that the panel cover has locked into place.

  2. 2

    Remove the air filters by pushing the centre tab of each filter up a little then pulling the filter down.

  3. 3

    Push down on the top of the air-cleaning filter so that it touches the tabs. Press up on the bottom of the filter so that it also touches the tabs. Remove the filter.

  4. 4

    Wash the air filters with warm water or vacuum them to clean them. Wash the air-cleaning filter with water.

  5. 5

    Place the air-cleaning filter and the air filters back in the unit then close the front panel cover.

    Air Conditioner Isn't Running

  1. 1

    Try adjusting the temperature setting. Press the down arrow on the remote's "TEMP" button to adjust the temperature until you hear the air conditioner turn on. If the air conditioner runs for too long, you can press the up arrow on the "TEMP" button to increase the temperature.

  2. 2

    Remove the battery casing cover from the back of the remote and remove the batteries. Replace them with fresh batteries.

  3. 3

    Check the windows and doors around the house. If any are open, the internal temperature of the house is probably being affected, which can prevent the air conditioner from turning on.

Tips and warnings

  • You can also use the remote's "Reset" button if the unit suddenly stalls while in use. Use an object with a thin, pointed end, as the button is too small to be pressed with a finger.
