Lennox Parts

How can I confirm a Lennox replacement part before ordering?
Match the complete Lennox equipment model and exact original part number first, then compare the listed component type and all verified electrical, dimensional, connector, mounting, and revision details.

Does the Lennox serial number matter when identifying replacement parts?
It can. The serial number may help identify the production period or configuration when the same model used more than one component. Provide it whenever available.

What does it mean when an older Lennox part number has been superseded?
A supersession means Lennox documentation identifies a newer approved number for the older part. Confirm the full supersession path rather than relying on a similar number or appearance.

Which details matter most for Lennox sensors and switches?
For sensors and switches, verify the exact part number and equipment model plus the applicable voltage, rating, connector, mounting, rotation, setpoint, or board revision shown in the listing.

What information should I provide HVACProSales for help with a Lennox part?
Provide the complete model, serial number, exact old-part number, component type, and clear photos of the equipment data plate and existing component. No personal information is needed.
