Heil Quaker ICP 1172809 Control Board

Replacing a faulty Heil Quaker ICP 1172809 Control Board is essential for restoring the sequence of operation in high-efficiency 2-stage furnaces. This genuine OEM 2-stage furnace control board acts as the central intelligence for your HVAC system, precision-managing the hot surface igniter (HSI), inducer motor speeds, and variable-speed blower timing. As a direct ICP 1172809 replacement part, it is engineered to handle the complex logic required for transitioning between low-fire and high-fire heating stages, ensuring optimal fuel utilization and equipment longevity. This board is compatible with a wide range of International Comfort Products (ICP) brands, including Heil, Quaker, Tempstar, Comfortmaker, and KeepRite. By utilizing an OEM HVAC control board, technicians ensure that factory-set safety protocols—such as flame rectification sensing and limit switch monitoring—remain intact. Whether you are troubleshooting a furnace control board with no 24V output to the gas valve or intermittent blower failure, this ICP 2-stage control module provides the specific timing and voltage regulation required for C8MPV and H8MPV series units.

• Precise 2-Stage Logic: Specifically designed to manage dual-stage gas valves and multi-speed or variable inducer motors for maximum comfort.
• Standardized Diagnostics: Features an onboard LED indicator for rapid troubleshooting of status codes, including ignition lockouts and limit circuit faults.
• Direct OEM Fit: Guaranteed physical and electrical compatibility with Heil Quaker ICP equipment, eliminating the need for field modifications.
• Integrated Safety Management: Constantly monitors flame signals and safety resets to ensure code-compliant furnace operation.
• Microprocessor Control: Advanced circuitry manages the blower-off delay and ignition sequences with higher reliability than older-generation boards.

What are the symptoms of a failing 1172809 control board?
Common indicators include the furnace failing to initiate the ignition sequence, the blower motor running continuously even without a call for heat, or the 3-amp fuse on the board blowing repeatedly due to an internal short.

Does this board replace the HK42FZ019 or HK42FZ020?
Yes, the ICP 1172809 is the current factory-authorized replacement for several previous iterations, including part numbers HK42FZ019 and HK42FZ020, used in many 80% and 90%+ AFUE 2-stage gas furnaces.

How do I verify compatibility for my specific furnace model?
Technicians should check the part number listed on the existing integrated furnace control (IFC) or verify the model number on the rating plate of the Heil, Tempstar, or KeepRite unit. This board is the primary replacement for the C8MPV, H8MPV, and T8MPV model families.
