      If your Airrex Air Conditioner is not working, first ensure the power cable is correctly connected. If it isn't, connect it properly. Next, check if the power button is in the 'OFF' position and press it to 'ON'. Also, verify if the fuse (supply) has blown and exchange it in the board if needed. Check if the breaker on the switchboard tripped and reset it after checking the load capacity. Finally, ensure the ambient temperature is within the operating temperature range.
