Description
The Reznor 207023 is a high altitude pressure switch specifically engineered to maintain safe and reliable operation of Reznor heating equipment at elevations between 7,501 and 10,000 feet above sea level. At higher altitudes, reduced air density affects combustion airflow and pressure differentials, making a properly calibrated pressure switch essential for safe furnace operation. This OEM replacement switch is factory-set to the correct trip point for the 7,501–10,000 ft altitude range, ensuring your Reznor unit performs to specification in mountain and high-elevation installations.
Key Features
- OEM Reznor replacement pressure switch
- Designed for high-altitude installations from 7,501 to 10,000 feet
- Factory-calibrated trip point for accurate altitude-specific pressure sensing
- Monitors combustion air pressure to prevent unsafe furnace operation
- Direct drop-in replacement for compatible Reznor heating equipment
- Helps maintain proper burner ignition sequencing at reduced air density
Application
This pressure switch is intended for use with Reznor gas-fired unit heaters and furnaces installed at high-altitude locations. When the unit is operated at elevations above sea level, thinner air reduces the pressure differential generated by the inducer motor. The Reznor 207023 is calibrated to account for these conditions, preventing nuisance lockouts while still providing the safety protection required by the equipment. Always verify compatibility with your specific Reznor model before installation.
Why Altitude Matters
Standard pressure switches are calibrated for sea-level air density. Installing a sea-level switch at high altitude can result in the switch failing to close — causing no-heat calls — or failing to open when a true fault exists. The Reznor 207023 eliminates this risk by providing a pressure setpoint matched to the 7,501–10,000 ft elevation band, keeping your equipment operating safely and efficiently in demanding mountain environments.
