Heil Quaker ICP 1179133 Pressure Switch

The Heil Quaker ICP 1179133 is a critical safety component designed for precise vent pressure sensing in high-efficiency gas furnaces. Functioning as a Single-Pole Single-Throw (SPST) switch, it triggers at a set point of 0.80" WC (Water Column) to ensure the draft inducer motor has established a sufficient vacuum before allowing the ignition sequence to proceed. This OEM replacement part is engineered for extensive compatibility across International Comfort Products (ICP) families, including Heil, Tempstar, Comfortmaker, and KeepRite units.

Built with a durable internal diaphragm, this furnace pressure switch features a standard 1/4" barb connection for a secure fit with existing pressure tubing. Professional installation is required to confirm the differential pressure matches system specifications and to prevent ignition failure codes or short cycling. As a veteran-grade HVAC replacement part, the ICP 1179133 provides the reliability needed for maintaining strict safety standards in residential heating systems.

• Precise Calibration: Factory-set to 0.80" WC for accurate inducer motor verification and system safety.
• Broad Compatibility: Genuine Heil Quaker ICP part designed for seamless fit in Heil, Arcoaire, and Tempstar gas furnaces.
• Rugged Design: Features a reliable SPST contact configuration and a standard 1/4" barb to ensure a leak-free vacuum connection.
• Efficient Diagnostics: Direct replacement for ICP 1179133 and ICP 609537 to resolve pressure switch stuck open faults.

What causes a pressure switch error on an ICP furnace?
Common culprits include a failing draft inducer, blocked flue vents, cracked pressure tubing, or a ruptured internal diaphragm within the switch itself.

Can I use a 1/4" barb switch to replace a different connection size?
No. The 1/4" barb connection is designed for specific hose diameters. Using adapters can lead to vacuum leaks and intermittent system lockouts.

How do I test a 1179133 pressure switch?
Using a multimeter set to continuity, check the SPST terminals while the inducer is running. If the 0.80" WC threshold is met but the circuit remains open, the switch requires replacement.
