Heil Quaker ICP 1174412 Pressure Switch
The Heil Quaker ICP 1174412 Pressure Switch is an essential safety component designed for precise airflow monitoring in gas-fired furnaces and HVAC systems. As a genuine OEM replacement part, it ensures the inducer motor establishes a proper draft before ignition, preventing hazardous exhaust buildup. This specific low pressure switch is factory-calibrated to a normally open state, configured to close when it senses a negative pressure of 0.45" WC and open at 0.20" WC. Reliable signaling to the control board is critical for preventing system lockouts and maintaining technical efficiency across supported Arcoaire, Comfortmaker, and Tempstar equipment.
The ICP 1174412 serves as the direct HK02ZB062 replacement, offering a drop-in fit for technicians servicing furnace pressure switch failures. Field-proven for its durability, this switch maintains tight tolerances to safeguard the heat exchanger and venting integrity. Whether you are troubleshooting an ICP furnace that won't ignite or addressing a pressure switch stuck open error, utilizing this factory-authorized part ensures the unit operates within its original engineered specifications for safety and performance.
Key Benefits:
- Precise Pressure Calibration: Opens at 0.20" WC and Closes at 0.45" WC for accurate safety interlocking.
- Direct Cross-Reference: Engineered as the exact substitute for HK02ZB062, ensuring electrical and mounting compatibility.
- Heavy-Duty Construction: Features a moisture-resistant diaphragm designed to withstand the high-cycle demands of modern HVAC duty cycles.
- Enhanced System Safety: Critical for verifying flue draft and preventing carbon monoxide accumulation during the startup sequence.
Common Questions:
How do I confirm if my pressure switch has failed?
Use a manometer to verify the inducer motor is pulling more than 0.45" WC. If the vacuum is sufficient but the 1174412 terminals show no continuity, the internal diaphragm or electrical contacts have likely failed.
Can this switch be used in 90% high-efficiency condensing furnaces?
Yes, it is compatible with various high-efficiency models, but check for water accumulation in the tubing first, as condensation often mimics a mechanical switch failure in 90+ units.
Will this part fix a furnace that starts but shuts down after a few seconds?
If the control board flashes a code for a pressure switch lockout, replacing the 1174412 is a primary solution once you have cleared potential flue or hose obstructions.
