  If your Daitsu Air Conditioner does not start, it could be due to a few reasons. Check if there was a power cut, and wait for the power to be restored. Ensure the unit is securely plugged into the wall receptacle. Also, the fuse might have blown and require replacement. Another reason may be exhausted batteries in the remote controller, so replace them. Finally, the timer setting may be incorrect, so wait or cancel the timer setting.

Why is my Daitsu Air Conditioner not cooling or heating well?

  If your Daitsu Air Conditioner isn't cooling or heating the room effectively despite airflow, it could be due to several reasons. First, ensure that the temperature is set correctly. You may also need to clean the air filter if it's blocked. Another cause might be open doors or windows, so make sure to close them. Also, check the air inlet or outlet of both the indoor and outdoor units for any obstructions, and clear them away before restarting the unit. Finally, the compressor might be under a 3-minute protection cycle; in this case, simply wait.
