Lennox 17V95 Pressure Switch Overview
The Lennox 17V95 is an OEM replacement pressure switch designed for Lennox furnaces rated in the 4500–10000 BTU range. With a set point of 0.95″ W.C. (inches water column), this switch monitors the negative pressure generated by the inducer motor to verify proper draft before allowing ignition to proceed — a critical safety function in modern gas furnace systems.
Key Features
- OEM Lennox replacement pressure switch
- Set point: 0.95″ W.C. (inches water column)
- Designed for Lennox furnaces in the 4500–10000 BTU range
- Monitors inducer motor draft to ensure safe furnace operation
- Prevents ignition if adequate negative pressure is not established
- Direct OEM replacement for accurate fit and reliable performance
How It Works
The pressure switch is a safety device that senses the negative pressure (vacuum) created by the draft inducer motor. When the inducer reaches the proper operating speed and establishes sufficient draft, the pressure switch closes, signaling the furnace control board to proceed with the ignition sequence. If draft pressure falls below the 0.95″ W.C. threshold — due to a blocked flue, failed inducer, or cracked hose — the switch remains open, locking out ignition and protecting against unsafe combustion conditions.
Application
- Direct replacement for failed or faulty Lennox OEM pressure switches
- Compatible with Lennox furnace models in the 4500–10000 BTU range
- Suitable for residential gas furnace applications
