Part numbers are taken from the manufacturer’s published repair parts documents and are listed so you can identify the right part. Manufacturers replace and supersede numbers over time, so confirm the number with your distributor before you order, and use factory-authorized parts on equipment under warranty. Replacing gas, electrical and refrigerant parts is work for a licensed technician. HVACopedia is not affiliated with any manufacturer; brand and model names only identify the equipment.
