Lennox Furnace Model Number: Where to Look
On Lennox furnaces, look for the model number on the blower compartment door or inside the front access panel. Some units list it near the gas valve, usually on the same equipment label as the serial number. Turn off power before removing an access panel, and copy the full model number exactly, including letters, numbers, and hyphens. Enter it in the search bar to narrow the catalog to parts made for your complete furnace model, not just parts that look similar. Matching the model first helps you confirm the correct fit across the unit's associated parts, saving time and avoiding compatibility mistakes during your repair.
