Look for the rating plate or label inside the front access panel, on the blower compartment door, or near the gas valve. You may need to remove the panel to read it, so turn off power to the furnace first and record every letter, number, and hyphen exactly as shown. Type it into our model number lookup and the catalog narrows to parts made for your unit, including the parts associated with your furnace. That means fewer wrong orders and a faster repair.
