  Michelle TrujilloAug 8, 2025
  If your ComfortStar Air Conditioner isn't operating, first check the power supply or reconnect the plug if it's loose. Also, the TIMER function may be active, so check and deactivate it if needed. Other potential issues include a damaged indoor/outdoor unit fan motor (replace it), a faulty compressor thermomagnetic circuit breaker (check and replace), faulty protective devices or fuses (replace them), loose connections (secure them), voltage outside the required range (adjust it), a damaged electronic control board (replace it) or the unit may have stopped to protect itself, in which case you should allow it to reset and monitor operation.

  If your ComfortStar Air Conditioner is not responding to commands, try moving the remote control closer to the indoor unit. Also, replace the batteries in the remote control. Make sure there are no obstacles blocking the signal between the remote and the unit.

Why ComfortStar Air Conditioner has insufficient airflow, either hot or cold?

  If your ComfortStar Air Conditioner isn't providing sufficient airflow (either hot or cold), start by adjusting the temperature setting appropriately. Then, check for and clear any obstructions from the air conditioner intakes and outlets. Also, clean or replace the air filter if it's dirty. Ensure the fan speed isn't set to minimum and increase it if necessary. Try to eliminate or reduce other heat sources in the room. Finally, the system may need to have the refrigerant recharged.
