Carrier 48XZN036090300 Control Board
HVAC systems will not run without this vital piece of hardware is in place and connected. The control board is designed to operate the gas valve, the ignition igniter, all the sensors and the blower all at once. A replacement board will need to pair with the part number from both the brand and specific model of your particular system. Be very careful when choosing a control board because of the diversity of certain brands.
Subtle hints your Carrier control board needs replacing
- Power to the circuit board has to be powered down and back up quite often for everything to run again
- System has a flashing error code displayed somewhere on the board
- Your HVAC unit does not run well
