On Luxaire furnaces, look for the model number on the blower compartment door or inside the front access panel. You may also find it on the unit's identification label near the gas valve. Copy the complete model number, including letters and numbers, before searching. Drop it into the search bar and you will see only the parts that fit your exact model. Because the model number identifies the entire furnace, it narrows the full catalog across every associated part category, not just flame sensors. This helps you confirm compatibility quickly and avoid ordering a part designed for a similar-looking unit.

Repair Clinic's online repair library is built to support Luxaire Furnace owners and technicians through every stage of the fix. Symptom-based articles narrow the likely cause, part testing videos verify the failing component, and step-by-step repair guides cover the installation with photos and video. Use the model number lookup to confirm the exact OEM part, and wiring diagrams back you up on the more technical steps.
