Heil Quaker ICP 1191351 Control Board

The Heil Quaker ICP 1191351 Control Board is a critical OEM replacement part designed to function as the primary logic controller for specific central furnace systems. As an integrated furnace control (IFC), this component manages the precise timing and sequencing of 120V ignition systems, gas valves, and flame sensing circuits. Built for high-reliability HVAC performance, the 1191351 ensures that the blower motor and inducer operate in perfect synchronization with the heating cycle to maintain optimal heat exchanger temperatures and prevent safety limit trips.

For technicians in the field, this board features a standard 120V AC power input and 15 Amp capacity, making it a rugged solution for commercial and residential environments. Its diagnostic LED indicators provide immediate feedback for troubleshooting common system faults such as pressure switch failures or limit circuit opens. If you are dealing with a dead blower or inconsistent ignition sequences in ICP, Heil, or Tempstar units, this board serves as a direct drop-in replacement for the 1187037, reducing "truck roll" time through factory-spec compatibility and simplified terminal layouts.

• Direct OEM Compatibility: Engineered specifically for ICP, Heil, and Tempstar central furnace models for a seamless fit.
• Precision Cycle Timing: Manages the ignition sequence and fan delays to maximize heating efficiency and equipment life.
• Enhanced Troubleshooting: Built-in diagnostic LEDs allow for rapid fault identification, reducing homeowner downtime.
• Heavy-Duty Relays: Rated for 15 Amp service to handle high-demand blower motor start-ups reliably.

What are the symptoms of a failing ICP 1191351 board?
Typically, you will see intermittent heating, the blower fan running constantly without a call for heat, or the furnace failing to initiate the nitride ignitor or spark sequence despite having 24V at the thermostat terminals.

Does this board replace the 1187037 model?
Yes, the 1191351 is the manufacturer-authorized cross-reference replacement for the older 1187037 control board, utilizing the same mounting footprint and wiring schematics.

Can I use this board for cooling control as well?
This is an integrated control board that handles both heating and cooling furnace functions, including the 24V compressor contactor signal and blower speed switching.
