Sensors, Probes & Switches
(Showing 24 of 207)Matching Lennox OEM Sensors, Probes & Switches
Shop Lennox oem sensors, probes & switches for verified commercial HVAC and equipment-service applications. Start with the exact OEM part number and complete equipment model rather than appearance alone. Confirm oem mpn; equipment model/serial; function; operating range or output; connector; mounting. Use a replacement or superseding number only when current manufacturer documentation supports the exact application, and request part-identification assistance when any critical specification is unclear.
Quick answer: Match the exact OEM MPN first, then verify oem mpn; equipment model/serial; function; operating range or output; connector; mounting before ordering.

Function and Range
Confirm temperature, pressure, airflow or safety function plus the documented range or output.

Lennox Sensors, Probes & Switches FAQs
How do I identify the correct OEM sensor?
Use the complete Lennox OEM MPN and equipment model, then verify every listed electrical, mechanical and mounting specification.
Are similar-looking sensors interchangeable?
Not automatically. Similar appearance does not confirm ratings, dimensions, connectors, revision or approved equipment application.
Why do connector and range matter?
Matching one rating is not enough; verify function, full electrical rating, terminals, connector, mounting and equipment application.
What should I send for sourcing help?
Provide the equipment brand, complete model and serial, original MPN, clear label and connector photos, dimensions, quantity and delivery ZIP.
