Lennox 80K80 Pressure Switch
The Lennox 80K80 pressure switch is a critical safety component designed for specific Lennox furnace models to ensure proper inducer motor performance and venting integrity. This SPST furnace pressure switch features a .65" WC set point, calibrated to monitor the negative pressure generated by the combustion blower. Engineered with a 1/4" barb connection, it provides a secure fit for standard vacuum tubing, preventing air leaks that can lead to intermittent ignition failures or furnace pressure switch stuck open codes. This Lennox OEM replacement part ensures the control board receives the necessary signal to proceed with the ignition sequence, maintaining system reliability under high-demand cycles.
Technical Specifications and Field Utility:
- Set Point: Factory calibrated at .65" WC for precise vacuum sensing.
- Configuration: Single Pole Single Throw (SPST) normally open contacts.
- Connection Port: 1/4 inch barb for standard pneumatic tubing.
- Application: Direct Lennox HVAC repair part for mid-efficiency and high-efficiency gas furnaces.
- Housing: Durable glass-filled polycarbonate construction for thermal resistance.
Frequently Asked Contractor Questions:
How do I troubleshoot a Lennox 80K80 pressure switch error?
Verify the inducer motor is reaching full RPM and check the 1/4" barb for debris. Use a manometer to confirm the system is pulling at least .65" WC. If the vacuum is sufficient but the pressure switch circuit remains open, the internal diaphragm or contacts may have failed.
Can I use a universal pressure switch as a substitute?
While universal kits exist, using the 80K80 OEM switch is recommended to ensure the .65" WC trip point matches the original furnace specifications for safety and sequence of operation.
