This OEM integrated furnace control board (part #1184783) is the brain of your ICP Tempstar Heil WFAR060A042A1 gas furnace. It sequences the entire heating cycle — energizing the inducer, proving the pressure switch, firing the hot surface igniter, opening the gas valve, monitoring flame through the sensor, and timing blower on/off delays. It also enforces the furnace's safety limits and stores diagnostic fault codes via its on-board LED. When the control board fails, symptoms range from a completely dead furnace to erratic operation: no ignition sequence, the blower running constantly, intermittent lockouts, or a flashing error code with no obvious cause. Boards fail from power surges, voltage spikes, corroded relays, and heat-stressed solder joints.
