Lennox Furnace Model Number: Where to Look
On Lennox furnace models, look for the model number on the blower compartment door, inside the front access panel, or near the gas valve. The identification label may also include the serial number, so copy the model number carefully, including letters, numbers, and hyphens. Drop it into the search bar and you will see only the parts that fit your exact model. This model lookup applies to the entire Lennox furnace, not just the thermocouple, and it narrows every associated parts category to the correct equipment. That saves time, reduces compatibility mistakes, and helps you start the repair with confidence.
