  Your Delta Air Conditioner might not be operating due to several reasons: a power failure or the plug being pulled out, a damaged indoor/outdoor unit fan motor, a faulty compressor thermomagnetic circuit breaker, faulty protective devices or fuses, loose connections, voltage issues, an active TIMER-ON function, or a damaged electronic control board. Check the power supply, connections, and components mentioned to identify the cause. If the appliance stops operating to protect itself, wait for it to reset.

  If your Delta Air Conditioner isn't providing sufficient airflow, either hot or cold, the issue could stem from several causes. Ensure that the temperature setting is appropriate for your needs. Check for any obstructions blocking the air conditioner's intakes and outlets. A dirty air filter can also restrict airflow, so clean or replace it. Additionally, verify that the fan speed is not set to the minimum. Other heat sources in the room can affect cooling performance, so remove them if possible. Finally, low refrigerant levels could be the culprit; in that case, check the refrigerant levels.

  If your Delta Air Conditioner isn't responding to the remote control, first ensure that the remote is close enough to the indoor unit. If that's not the issue, replace the batteries in the remote control. Also, check for any obstacles between the remote control and the signal receiver on the indoor unit and remove them.
