Heil Quaker ICP 1179391 Control Board

The Heil Quaker ICP 1179391 Ignition Control Board is a critical OEM replacement component designed to manage the ignition sequence and safety logic in International Comfort Products (ICP) gas-fired furnaces. This 24V integrated furnace control regulates the draft inducer motor, gas valve, and blower operations while providing continuous flame sensing and safety lockout protection. Engineered with advanced microprocessor technology, the ICP 1179391 ensures precise timing for trial-for-ignition and blower delay-off cycles, maintaining high system efficiency. As a direct replacement for parts such as R03I009 and White Rodgers 50A55-843, this board is built to withstand the thermal stress of high-cycle residential heating environments. Field technicians can utilize the integrated diagnostic LED for rapid troubleshooting of pressurized switches or limit circuit faults. Correct furnace circuit board replacement requires verifying line voltage polarity to prevent control lockout or intermittent ignition failure.

• Precision timing control manages the furnace ignition sequence and blower operation for optimized heat exchange.
• On-board diagnostics feature an LED status indicator to help contractors quickly identify failed pressure switches or open limits.
• Robust silicone carbide compatibility ensures reliable interface with hot surface igniters in various Heil, Tempstar, and Comfortmaker models.
• Direct OEM fitment reduces installation time by matching existing wiring harness footprints and 24V terminal logic.

Is the 1179391 compatible with all ICP furnaces?
This board fits a wide range of Heil, Quaker, and Tempstar units, but you must verify your specific model and serial number to ensure compatibility with your existing harness and igniter type.

What does a flashing LED on my ICP control board mean?
The flashing LED is a diagnostic tool; common codes include 3 flashes for a pressure switch failing to close or 4 flashes indicating an open primary limit circuit.

Can I use this board to replace a White Rodgers 50A55-843?
Yes, the 1179391 is the authorized OEM replacement for several White Rodgers integrated controls used in ICP equipment.
