Heil Quaker ICP 1191550 Pressure Switch

The Heil Quaker ICP 1191550 Pressure Switch is an essential OEM dual pressure switch engineered for International Comfort Products (ICP) high-efficiency furnaces. This specific vent pressure switch is the direct performance replacement for the discontinued 1184413 model, as well as cross-referenced numbers BA20266 and HK06NB012. As a safety-critical component, it features a dual-stage configuration with precise set points: the High Pressure Switch (HPS) housing triggers at 0.34" WC, while the Low Pressure Switch (LPS) collector box operates at 0.68" WC. By continuously monitoring static pressure and inducer motor velocity, the ICP 1191550 ensures that combustion gases are properly vented, preventing hazardous operation due to flue blockages or mechanical failures. Designed for seamless integration into Tempstar, Comfortmaker, and Heil multi-stage equipment, this furnace pressure switch restores factory-standard safety and combustion efficiency to residential and commercial heating systems.

Key Benefits

• Direct OEM Replacement: Engineering-exact fit for legacy 1184413 and BA20266 units, eliminating the need for field modifications.
• Precise Dual Sensing: Features calibrated 0.34" and 0.68" WC set points for accurate drafting and safety shut-off protocols.
• Multi-Brand Compatibility: Verified for use across the International Comfort Products portfolio, including Heil, KeepRite, and Arcoaire.
• Enhanced System Safety: Protects against heat exchanger damage and exhaust gas backup by ensuring proper inducer airflow.
• Veteran-Grade Build: Robust Honeywell-designed housing built to withstand the thermal cycles of high-efficiency HVAC environments.

Common Questions

Technicians often identify a failed switch when the furnace inducer runs but the ignition sequence fails to initiate. Use a manometer to verify if the inducer pressure meets the 0.34" or 0.68" WC threshold; if the vacuum is sufficient but the switch remains open, the component requires replacement.

Yes, the ICP 1191550 is a dual-stage assembly specifically designed for equipment that requires different pressure thresholds for low-fire and high-fire operation phases.

Since the 1191550 is a factory-integrated dual assembly, the entire unit must be replaced to ensure the safety circuit logic remains synchronized and compliant with manufacturer specifications.
