This is the master category for every furnace and HVAC replacement part carried by Furnace Part Source, spanning heating, cooling, and control components across residential, commercial, and industrial equipment. Whether you're troubleshooting a specific failure or stocking parts for a service route, this category is the starting point for locating what you need.

Because this catalog spans thousands of individual parts across dozens of subcategories, the fastest way to find what you need is to search by exact OEM part number or browse into a specific subcategory, such as motors, blowers, ignitors, or control boards.

Major Subcategories

This category includes dedicated subcategories for:

  • Motors and blowers, including main blower motors, inducer motors, and blower assemblies.
  • Ignition components, including hot surface ignitors, pilot burners, and flame sensors.
  • Controls, including control boards, ignition modules, relays, and switches.

  • Structural and mechanical parts, including housings, brackets, bearings, and pulleys.
  • Combustion and venting parts, including burners, gas valves, heat exchangers, and vent dampers.

How to Find the Right Part

Before ordering, check the equipment data plate and the existing part for the model number, serial number, and part number. Because this category covers such a wide range of equipment types and brands, matching by exact part number is the most reliable way to confirm compatibility.

For best fit, compare:

  • Original part number
  • Equipment model and serial number
  • Voltage, fuel type, and system type
  • Replacement or superseded part number, if applicable
