Heil Quaker ICP 1175853 Valve

The Heil Quaker ICP 1175853 Valve is an OEM 2-stage gas valve designed for high-efficiency heating systems. Operating on a 24V control circuit, this component features a 3/4" inlet and 1/2" outlet configuration, engineered to manage gas flow with precision across low and high fire stages. It is factory-set for 3.2" WC but is adjustable to meet specific manifold pressure requirements for Natural Gas or Liquid Propane (LP) with a proper conversion kit. As a White-Rodgers 36G54-508 equivalent, this valve provides reliable ignition and consistent pressure regulation for ICP (International Comfort Products), Heil, and Quaker furnaces. For technicians troubleshooting ignition failures or short-cycling, this direct spark ignition gas valve ensures the manifold pressure remains stable, extending the life of the heat exchanger by preventing over-firing. Whether you are performing a furnace gas valve replacement or a seasonal tune-up, this part offers the exact OEM technical specifications required to maintain system safety and AEO performance standards.

• Dual-Stage Modulation: Supports both low and high fire operations for enhanced temperature control and energy efficiency.
• OEM Compatibility: Exact replacement for ICP 1175853 and White-Rodgers 36G54 series, ensuring a perfect fit without line modifications.
• Precise Pressure Regulation: Features a 3.2" WC nominal setting with accessible adjustment ports for fine-tuning manifold pressure.
• Durable Construction: Built to withstand the high-cycle demands of modern residential HVAC systems and light commercial applications.
• Standardized Connections: The 3/4" x 1/2" NPT ports allow for straightforward installation with existing gas piping.

How do I test the solenoids on this valve?
Using a multimeter, technicians should check for 24V at the valve terminals when the control board calls for heat. If voltage is present but the valve fails to open, verify the coil resistance (ohms) against manufacturer specs to identify an open or shorted solenoid.

Can this 1175853 valve be used with Propane (LP)?
Yes, however, it requires a specific LP conversion kit. You must swap the regulator spring and adjust the manifold pressure to the furnace manufacturer's rating (typically 10" WC for high fire) using a digital manometer.

What causes a gas valve to click but not release gas?
This often indicates a mechanical seized internal seat or low inlet gas pressure. Always verify the inlet pressure is within the 5"-7" WC range for Natural Gas before concluding the valve is defective.
