  If your Daikin Air Conditioner is running but not cooling or heating effectively, consider these potential causes: * Obstructions: Check if the air inlet or outlet of either the outdoor or indoor unit is blocked. If so, remove the obstacle to ensure proper ventilation. * Dirty Air Filter: A clogged air filter can restrict airflow. Ask a qualified service person to clean the air filters. * Improper Settings: Make sure the temperature, fan speed, and airflow direction are appropriately set. * Open Doors/Windows: Ensure doors and windows are closed to prevent drafts. * Direct Sunlight: Use curtains or blinds to block direct sunlight, which can affect cooling performance.

  If your Daikin Air Conditioner stops shortly after you turn it on, it might be due to: * Blocked air inlets or outlets: Ensure that neither the indoor nor outdoor unit's airflow is obstructed. Clear any obstacles to allow for proper ventilation. * Clogged air filter: A dirty air filter can cause the unit to overheat and shut down. Ask a qualified service person to clean the air filters.

  If your Daikin Air Conditioner isn't cooling or heating sufficiently, make sure that the air inlet or outlet of the outdoor or indoor unit isn't blocked by any obstacles. Remove any obstructions to ensure proper ventilation. Also, check if the air filter is clogged and have a qualified service person clean the air filters. Verify that the set temperature, fan speed, and airflow direction are appropriate for your needs. Ensure doors and windows are closed to prevent drafts, and use curtains or blinds to block direct sunlight. Consider whether there are too many people in the room or excessive heat sources, which could affect cooling performance.

  If your Daikin Air Conditioner doesn't turn on at all, first check if a fuse has blown and turn off the power supply. Next, check if the power circuit breaker is blown. If the tab is in the OFF position, turn the power on using the breaker switch. However, if the tab is in the trip position, do not attempt to turn the power on and contact your local dealer. Finally, check for a power failure and wait until power is restored. If a power failure occurred during operation, the air conditioner will automatically restart once the power supply recovers.

  If your Daikin Air Conditioner stops after starting, check whether the air inlet or outlet of the outdoor or indoor unit is blocked by obstacles. If there are any, remove them to ensure proper ventilation. Note that the horizontal blades at the air outlet close when the indoor unit stops. Also, check if the air filter is clogged and arrange for a qualified service person to clean it.
