Overview
This OEM control board (part number 1178358) with its ignition control module (1177661) is the brain of the ICP Tempstar Heil WPG3424060RKC1 packaged unit. It sequences the entire heating cycle — proving the pressure switch, energizing the igniter, opening the gas valve, monitoring flame via the sensor, and timing the blower on/off delays. It also manages safety lockouts and flashes diagnostic fault codes. When the board fails, symptoms range from a completely dead furnace to no ignition, intermittent operation, erratic blower behavior, or repeated lockouts with no other failed component. Boards commonly fail from power surges, moisture, relay wear, or burned ignition-control traces.
