Carrier 50XL-A30 Control Board
The Carrier 50XL-A30 control board is designed to control everything including the gas valve, the igniter, most sensors as well as the blower all in one unit. The HVAC system will be unable to run at all without the control board in place and connected. The control board you choose should have part numbers that match both the make and model of furnace or air handler you have. It is of utmost importance while choosing a new control board due to the many differences between certain brands.
Clues of a poorly performing control board
- AC unit or heating unit is unable to start correctly
- There may be an error code indicated directly on the control board
- Power to the circuit board has to be powered down and back up quite often for the thermostat to kick in
