Description
The International Comfort Products 1177767 is a factory-specified High Altitude Dual Pressure Switch engineered as a direct OEM replacement for compatible ICP heating equipment. Designed to monitor and verify proper airflow and combustion conditions, this dual pressure switch plays a critical role in the safe operation of your furnace or air handler — particularly in high-altitude installations where air density differences can affect pressure readings and combustion performance.
Key Features
- OEM-grade dual pressure switch designed for high-altitude HVAC applications
- Monitors both positive and negative pressure to confirm safe inducer and combustion airflow conditions
- Helps prevent furnace operation under unsafe or out-of-spec pressure conditions
- Direct drop-in replacement for compatible International Comfort Products (ICP) furnace models
- Engineered to maintain accurate switching performance at elevated installations where standard switches may not perform reliably
Why High Altitude Matters
At higher elevations, reduced atmospheric pressure can alter the pressure differential across the heat exchanger and inducer assembly. A standard pressure switch calibrated for sea-level operation may not trip correctly under these conditions. The ICP 1177767 is specifically calibrated for high-altitude environments, ensuring the furnace’s safety controls function as intended regardless of installation elevation.
Application
- Designed for use with International Comfort Products (ICP) furnaces and heating systems
- Ideal for replacement in high-altitude service areas
- Consult your equipment’s service manual to confirm compatibility with your specific model
