Lennox 10U94 Pressure Switch
The Lennox 10U94 Pressure Switch is the OEM replacement for 103614-09, engineered specifically for high-efficiency gas furnace applications. This SPST pressure switch is factory-calibrated to a .90" wc set point, providing critical safety monitoring of the inducer motor and venting system vacuum. Designed for Lennox, Armstrong, and Ducane units, it serves as a direct furnace air pressure switch replacement for several legacy components, including 93W94 and 80W67. As a fundamental HVAC safety limit, this switch ensures the combustion process only initiates when proper static pressure is maintained, preventing hazardous operation. The 10U94 features a durable diaphragm and standard terminal connections for a seamless fit into existing wiring harnesses. For techs troubleshooting "pressure switch stuck open" codes, this genuine component restores factory-spec reliability to the heating cycle.
Key Benefits:- Direct OEM Compatibility: Verified Lennox 10U94 replacement for 103614-09, 93W94, 80W67, and 10U9401.
- Precise Calibration: Fixed .90" Water Column SPST (Single Pole Single Throw) configuration for exact system matching.
- Universal Application: Fits a wide range of Lennox-family 95% and 90% AFUE furnaces.
- Inducer Safety: Reliably monitors inducer blower performance to ensure safe venting of flue gases.
- Can I use a different WC rating if the .90" is unavailable? No. Pressure switches are safety devices calibrated to specific furnace venting requirements; changing the rating can lead to improper combustion or safety hazards.
- What does it mean if my furnace is throwing a "Pressure Switch Open" code? This often indicates a failed 10U94 switch, a restricted vent pipe, or a failing inducer motor that cannot pull the required vacuum.
- Is the 10U94 a direct swap for the 103614-09? Yes, the 10U94 is the consolidated manufacturer replacement for the older 103614-09 part number.
