Description
The International Comfort Products 1192717 Dual Air Pressure Switch is an OEM replacement component engineered to maintain safe and efficient operation in ICP heating and cooling systems. This dual air pressure switch monitors the negative pressure produced by the inducer motor during the heating cycle, verifying that proper draft conditions exist before allowing the gas valve to open. By sensing pressure on two circuits simultaneously, it provides an added layer of protection against flue blockages, inducer failures, and unsafe combustion conditions.
Key Features
- Genuine OEM International Comfort Products replacement part
- Dual-sensing design monitors two pressure points for enhanced safety
- Verifies inducer motor operation and proper flue draft before ignition
- Helps prevent unsafe combustion by shutting down the heating sequence on pressure fault
- Direct drop-in replacement for compatible ICP furnace models
- Durable construction for long-term, reliable performance
Application
This dual air pressure switch is designed for use in International Comfort Products furnaces and air handlers that require dual-port pressure sensing. It is a critical safety control in the furnace’s ignition sequence, ensuring the system will not attempt ignition unless safe draft conditions are confirmed.
Installation Notes
- Always verify compatibility with your specific ICP model before installation
- Disconnect power before servicing or replacing the pressure switch
- Inspect hose connections and ports for cracks or blockages during replacement
- Consult the equipment service manual for pressure switch setpoint specifications
