Before replacing the board, count the LED blinks — the error code tells you what actually failed. Sometimes it’s a $15 fuse, not a $140 board.

Description
If your furnace won’t ignite, shows error codes, or the blower won’t start, the control board controls all of it. The terminal board provides the wiring connection points for the control circuit. If terminals are burned, corroded, or broken, the board needs to be replaced. This is a Carrier OEM part.
