The integrated furnace control (IFC) board serves as the brain of your system — sequencing the blower motor, managing heat stages, monitoring safety inputs, and communicating fault codes via LED diagnostics. When this board fails, common symptoms include a blower that won't start or run continuously, a system stuck in lockout, erratic cycling, or a complete loss of heating and cooling response even when the thermostat is calling for conditioned air.
