International Comfort Products 1176957 Pressure Switch for HVAC Systems

The International Comfort Products 1176957 is a replacement pressure switch designed for use in ICP heating and cooling systems. Pressure switches are critical safety components that monitor air pressure within the HVAC system — typically in the inducer or draft blower assembly — and shut down furnace operation if unsafe pressure conditions are detected, helping to prevent combustion gases from entering the living space.

Key Features:

• Direct OEM replacement for International Comfort Products systems
• Monitors negative or positive pressure in the inducer/draft assembly
• Activates to interrupt ignition sequence if pressure falls outside safe operating range
• Designed to meet original equipment specifications for reliable, drop-in fit
• Durable construction for long service life in residential and light commercial HVAC applications

The ICP 1176957 pressure switch is engineered to restore safe, reliable furnace operation. Using the correct OEM replacement part ensures compatibility with your system's control board and blower assembly, minimizing the risk of nuisance lockouts or improper pressure sensing. Always verify the switch rating and hose port configuration before installation.
