On ICP furnaces, look for the model number on the blower compartment door, inside the front access panel, or near the gas valve. The rating plate or data label usually lists the model and serial numbers together, so copy the model number exactly, including letters and numbers, while keeping similar-looking characters in the right order. Type it into our model number lookup and the catalog narrows to parts made for your unit. Using the complete furnace model filters the full ICP parts selection, not just one category, so you can compare parts that match the equipment in front of you. That means fewer wrong orders and a faster repair.
