Overview
The International Comfort Products 1445587 is a factory-engineered pressure switch designed to deliver dependable draft proving and safety protection in gas furnace and heating applications. Featuring a 1.78″ water column (wc) set point, this switch monitors negative pressure generated by the inducer assembly and interrupts the ignition sequence if safe operating conditions are not met — helping prevent unsafe combustion and protecting heat exchanger integrity.
Key Features
- 1.78″ w.c. set point for precise draft pressure sensing
- SPDT (Single Pole Double Throw) switching action for versatile circuit integration
- Dual 1/4″ barb port connections for easy hose attachment and secure sealing
- OEM replacement part engineered to International Comfort Products specifications

Application
This pressure switch is a direct OEM replacement for select International Comfort Products (ICP) gas furnaces. It is installed in the inducer circuit and monitors flue pressure to confirm adequate draft before the control board advances to ignition. Always verify compatibility with the specific furnace model before installation.
