Carrier Air Conditioner Control Panel Not Working – What to Do
Consider resetting the air conditioner if the control panel stops working or goes blank. The panel usually has a reset button, small but marked. You may find it directly on the panel or hidden under the digital display. When you find the button, press and hold it for about three seconds.
If the air conditioner does not respond, press the button again and hold it for an extra three seconds. The control panel should show light and give it some time to fully reset. The reset should fix any minor issue with the air conditioner.
If the reset does not work, the problem may stem from loose connections in the unit. Since it requires opening the air conditioner, you may need professional help. But before that, ensure the unit is getting enough power from the circuit breaker. Also, the power outlet, if it is directly connected to one, must be producing enough voltage to power the unit. Otherwise, an HVAC technician needs to troubleshoot further and find the source of the problem.
When the Thermostat Does Not Work
If the air conditioner uses the external thermostat as the control panel and the thermostat stops working, check the batteries. Dead batteries stop the thermostat from working, and the batteries can die if they have been in use for a long time. Replace the batteries and try the thermostat again.
But if replacing the batteries does not fix the problem, there may be loose wires or issues with the wires. It is best that a technician checks and fixes the wiring problem if you are not handy with them, especially because it concerns electricity. Contact the Carrier Service Center for further assistance or hire an independent technician.
Another part to check is the circuit breaker. A recent power outage, voltage spike, or a simple malfunction can trip it. Turn the breaker on if it is tripped and check the thermostat. If it remains off, the breaker may have blown a fuse. That will require replacing the fuse and you need the help of a technician. But if the breaker trips again, there may be a more serious internal issue that needs immediate attention.
One possibility is that the thermostat is old and needs a replacement. While it can last up to twenty years, usage can wear it out faster. Otherwise, it has been in use too long and is due for retirement. Therefore, consider replacing it and use professional help for the job unless you know your way around the system.
