International Comfort Products 1193107 SPST Pressure Switch Overview
The International Comfort Products (ICP) 1193107 is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch rated at .35″ water column (wc). Designed to monitor negative pressure in the flue gas venting system of ICP heating equipment, this switch plays a critical safety role — verifying that the inducer blower is generating adequate draft before allowing the ignition sequence to proceed.
Key Features
- OEM International Comfort Products replacement part — ensures proper fit and function
- SPST (Single-Pole, Single-Throw) switching action for straightforward open/close draft sensing
- Rated set point of .35″ water column (wc) for precise draft pressure monitoring
- Protects against unsafe furnace operation caused by blocked flues, failed inducer motors, or restricted venting
- Designed for direct drop-in replacement in compatible ICP furnace and air handler applications
- Durable construction built to withstand the thermal and pressure cycling demands of residential and light commercial HVAC systems
How It Works
The pressure switch is connected to the inducer motor housing via a rubber hose. When the inducer blower reaches the correct operating speed, it generates a negative pressure that closes the SPST switch contacts at the .35″ wc set point. This closed signal confirms to the furnace control board that safe draft conditions exist, allowing the heating sequence to continue. If adequate pressure is not achieved — due to a blocked vent, failed inducer, or collapsed hose — the switch remains open, locking out ignition and protecting the system and occupants.
Application
- Direct OEM replacement for International Comfort Products (ICP) furnaces and heating systems
- Compatible with systems requiring a .35″ wc SPST pressure switch
- Suitable for residential and light commercial HVAC applications
Why Choose OEM ICP Parts?
Using genuine OEM replacement components like the ICP 1193107 ensures your equipment operates within manufacturer specifications, maintains warranty compliance where applicable, and delivers the reliability your customers expect. Aftermarket substitutes may not match the precise set point calibration required for safe, code-compliant operation.
