Heil Quaker ICP 1445587 Pressure Switch
The Heil Quaker ICP 1445587 Pressure Switch is a critical safety component designed for high-efficiency HVAC systems, specifically engineered to monitor induced draft blower performance. This SPDT (Single Pole Double Throw) switch features a precise 1.78" WC set point, ensuring the combustion process only initiates when proper static pressure is established. Built for durability in demanding environments, it utilizes dual 1/4" barb connections for secure pneumatic tubing attachment. This OEM replacement pressure switch is essential for resolving furnace pressure switch stuck open codes and ensuring the limit circuit closes during the ignition sequence. Its calibrated diaphragm responds accurately to vacuum changes, preventing unburned fuel release and protecting the heat exchanger from improper venting conditions. When replacing an ICP furnace pressure switch, verifying the WC rating is vital for maintaining the manufacturer's specified sequence of operation and system safety certification.
Technical Specifications and Benefits- Factory Calibrated 1.78" WC: Ensures precise set point accuracy for induced draft motor verification.
- SPDT Switch Configuration: Provides versatile electrical switching capabilities for integrated furnace control boards.
- Dual 1/4" Barb Ports: Allows for standard hose connections common in Heil, Quaker, and Tempstar equipment.
- OEM Compatibility: Direct fit for multiple ICP brands, reducing diagnostic time and installation errors for HVAC contractors.
- Rugged Housing: Designed to withstand the thermal cycling and vibration typical of residential mid-to-high efficiency furnaces.
How do I troubleshoot an ICP 1445587 pressure switch that won't close?
First, verify that the inducer motor is reaching full RPM and that the flue pipe is free of obstructions. Use a manometer to confirm the negative pressure at the 1/4" barb connection exceeds the 1.78" WC threshold. If the pressure is sufficient but the SPDT switch remains open, the internal diaphragm or electrical contacts have failed.
Can I use a universal pressure switch to replace this 1.78" WC model?
While universal switches exist, it is standard practice to use the exact OEM ICP pressure switch. The 1.78" WC rating is specific to the heat exchanger’s airflow requirements; installing a switch with a lower rating can lead to unsafe combustion or "nuisance tripping" during cold startups.
What are the symptoms of a failing furnace pressure switch?
Most systems will display a specific LED flash code on the control board indicating a pressure switch lockout. You will typically see the inducer motor start, but the igniter will fail to glow because the safety circuit remains open, preventing the gas valve from energizing.
