It is always a good practice to disconnect and isolate the power supply when you are troubleshooting the control board.

The next most common step in ac troubleshooting is checking for a dirty air filter. Airflow direction control may not be engaged with the universal remote control. If the fan isn t working that can cause the coil to freeze. Check the outdoor cooling or condensing unit to see if it s running.
