The control board is the brain of the furnace — it sequences the inducer, igniter, gas valve, and blower, monitors safety switches, and manages diagnostics. Supplied as a complete kit for a direct OEM replacement. When the board fails, symptoms include a completely dead furnace, no response to thermostat calls, blower or inducer running continuously, error\/fault LED codes, or intermittent operation and random lockouts.
