Heil Quaker ICP 1172550 Control Board

This Heil Quaker ICP 1172550 Control Board is a genuine OEM 1-stage furnace control board designed for high-reliability sequence management in International Comfort Products (ICP) forced-air systems. As the primary integrated furnace control (IFC), this module regulates the ignition sequence, inducer motor timing, and blower operation for brands including Heil, Tempstar, Comfortmaker, and Arcoaire. It effectively replaces legacy part numbers HK42FZ018, 1172550-S, and CEPL130590-01, ensuring a direct-fit solution for technicians servicing 80+ and 90+ AFUE units. The board features an integrated 5-amp fuse to protect sensitive low-voltage 24VAC circuits from overcurrent and utilizes clear terminal labeling for HUM, FAN, and HEAT/COOL speeds. Whether you are addressing a furnace not heating issue or a faulty ignition control module, this 1172550 replacement board provides the robust diagnostic capabilities needed to monitor safety limit strings and pressure switches, maintaining peak operational safety and performance.

• Universal ICP Compatibility: Direct OEM replacement for a wide range of single-stage gas furnaces under the Heil, Tempstar, and KeepRite families.
• Integrated Circuit Protection: Features a 5-amp automotive-style fuse to prevent board failure during external electrical shorts or thermostat wiring faults.
• Precision Timing Logic: Expertly manages the sequence of operation, including pre-purge, ignition trials, and blower-off delay for maximum efficiency.
• Diagnostic Reliability: Simplifies troubleshooting with clear terminal identification and monitoring of safety limit circuits and pressure switches.

• How do I confirm if my 1172550 board is faulty? Check for 24VAC at the transformer, inspect the 5-amp fuse for continuity, and look for burnt traces or failed relays on the circuit board.
• Will this work with a 2-stage furnace? No, this is specifically engineered for 1-stage furnace applications. Verify your model number before installation.
• What causes these boards to fail most often? Electrical surges, moisture in the furnace cabinet, or excessive vibration from a failing blower motor are common failure points.
