Heil Quaker ICP 1177661 Control Module

The Heil Quaker ICP 1177661 Control Module is a critical integrated furnace control board designed for high-efficiency direct spark ignition (DSI) and hot surface ignition (HSI) systems within ICP heating equipment. Engineered to manage the blower motor, inducer, and gas valve sequencing, this direct replacement control board ensures precise flame sensing and safety lockout protocols. As a drop-in OEM furnace control module, it matches the electrical specifications of original factory components, maintaining 24VAC input signal integrity and providing reliable terminal connections for common HVACR field wiring. This solid-state module is built to withstand the thermal cycling and vibration common in residential air handlers and furnaces, offering a robust solution for troubleshooting intermittent ignition failures or faulty relay contacts on older Heil, Quaker, and Comfortmaker units.
