If your Daikin Inverter stops suddenly and the OPERATION lamp is blinking, clean the air filters or remove any obstacles. Then, turn the breaker OFF, turn it back ON, and try operating the air conditioner using the remote controller.
Why is the cooling or heating effect poor on my Daikin FTX25JV1NB?
A poor cooling or heating effect from your Daikin Inverter could be due to several reasons. Ensure the air filters are clean and that nothing is blocking the air inlet or outlet of either the indoor or outdoor units. Check if the temperature setting is appropriate, and make sure windows and doors are closed. Also, verify that the airflow rate and direction are set correctly and that the unit is not set to Intelligent Eye mode.
Why does my Daikin FTX25JV1NB Inverter outdoor unit emit water or steam?
The outdoor unit emits water or steam due to the following reasons: * In HEAT mode, the frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation. * In COOL or DRY mode, moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.
Why hot air does not flow out soon after starting Daikin Inverter heating operation?
If hot air does not flow out soon after starting the heating operation, you should wait for 1 to 4 minutes.
Why Daikin FTX25JV1NB operation does not start soon?
If the operation does not start soon, you should wait for about 3 minutes.
What to do if my Daikin Inverter air conditioner does not operate and the OPERATION lamp is off?
If your Daikin Inverter isn't operating and the OPERATION lamp is off, check a few things: see if a breaker has turned OFF or a fuse has blown. Also, check for a power failure. Ensure batteries are correctly installed in the remote controller, and verify that the address switch in the remote controller is set correctly. Finally, confirm that the timer setting is correct.
Why does my Daikin Inverter indoor unit give out an odor?
The odor from your Daikin Inverter's indoor unit occurs when smells from the room, furniture, or cigarettes are absorbed into the unit and discharged with the airflow. If this happens, it is recommended to have the indoor unit cleaned by a technician. Consult the service shop where you bought the air conditioner.
What to do if my Daikin FTX25JV1NB Inverter air conditioner malfunctions with lightning or radio waves?
If your Daikin Inverter malfunctions due to lightning or radio waves, turn the breaker OFF, then turn it back ON. After that, try operating the air conditioner with the remote controller.
What to do if Daikin FTX25JV1NB heating operation stops suddenly and a flowing sound is heard?
If the heating operation stops suddenly and a flowing sound is heard, you should wait for about 3 to 8 minutes.
