Heil Quaker ICP 1171734 Circuit Board

The Heil Quaker ICP 1171734 Circuit Board is an OEM furnace fan control board designed for high-reliability operation in International Comfort Products (ICP) equipment, including Heil, Tempstar, and Comfortmaker furnaces and air handlers. As a seasoned tech, you know that the "brain" of the system must handle precise sequencing. This solid-state control board features an integrated Time Delay Relay (TDR), which is critical for optimizing blower operation cycles and improving overall heat exchange efficiency by managing post-cycle airflow. This board is a direct replacement for legacy units, ensuring a 1:1 fit without the need for field modifications or bracket fabrication. It manages voltage distribution to the blower motor and monitors safety circuit inputs to maintain system integrity. Whether you are addressing a fan control relay failure or intermittent communication issues within the air handler, this genuine ICP replacement part provides the exact electrical specifications required to restore factory-standard performance to the HVAC system.

Key Benefits:

• Integrated Time Delay Relay: Optimized for residual heat recovery, preventing short-cycling and increasing blower motor longevity.
• OEM Compatibility: Designed specifically for ICP HVAC equipment, including Heil Quaker, Tempstar, and Arcoaire furnaces.
• Direct Replacement: Eliminates the need for complex wiring adaptations by matching OEM terminal configurations.
• Rugged Solid-State Construction: Engineered to withstand the thermal stress and vibration common in residential cabinet environments.

Common Questions:

• Which furnace models use the 1171734 board? This board is commonly found in ICP gas and electric furnaces, as well as specific air handler models requiring fan delay logic. Always check your specific wiring diagram for the part number.
• Does this board replace the fan relay? Yes, this integrated fan control manages the switching duties previously handled by standalone fan relays in older models.
• What does the Time Delay Relay do? The TDR keeps the blower running for a set duration after the thermostat is satisfied, ensuring all conditioned air is pushed through the ductwork.
