This OEM integrated control board is the brain of the ICP WPG3244060LKC1 packaged gas/electric unit. It manages the entire heating sequence — receiving the 24V thermostat call, energizing the inducer, proving the pressure switch, firing the hot surface igniter, opening the gas valve, monitoring flame, and timing the blower on/off delays. It also coordinates safety lockouts from the limit and rollout switches. This listing covers the circuit board (OEM 1178358) and its companion ignition control module (OEM 1177661). When this board fails you typically see no ignition sequence at all, random no-heat lockouts, an inducer that runs but never lights, or a board with a continuously flashing fault LED.
