On Miller furnaces, look for the model number on the blower compartment door, inside the front access panel, or near the gas valve. The information appears on a rating plate or identification label and may be listed beside the serial number, so copy the complete model number carefully, including letters and hyphens. Enter it in the model number search to pull up the parts matched to your unit. This filters the full Miller furnace catalog, not just heat exchangers, to parts designed for your specific furnace. With the correct model selected, you can compare compatible parts quickly and avoid ordering based on appearance alone. That means fewer wrong orders and a faster repair.
