Furnace Part Source carries brand-specific burner parts from manufacturers such as Rheem-Ruud, Lochinvar, A.O. Smith, Utica-Dunkirk, Carrier, Modine, Laars, Bradford White, Midco, and more. Match your OEM part number, equipment model number, fuel type, and burner configuration before ordering.

Furnace Burners and Gas Burner Replacement Parts

Furnace burners are combustion-system parts that help deliver and shape the flame used to heat compatible furnace and heating equipment. This category includes furnace burners, gas burner assemblies, burner kits, pilot burners, burner supports, and related burner replacement parts for a range of heating systems.

Because burner parts are built around specific equipment designs, the correct replacement depends on more than appearance. Before ordering, match the OEM part number, equipment model number, fuel type, burner configuration, and any required gasket, bracket, or mounting detail listed in your service documentation.

How Furnace Burners Work

A furnace burner helps create the controlled flame used during the heating cycle. In many gas heating systems, fuel moves from the gas valve to the burner assembly, where it mixes with combustion air and is ignited by a pilot burner, spark ignitor, or hot surface ignitor, depending on the equipment design.

Once ignition occurs, the burner flame heats the heat exchanger so warm air can move through the system. The exact burner design can vary by manufacturer, model, fuel type, and equipment configuration. Always match the replacement burner to the OEM part number, service documentation, and natural gas or LP requirements for the unit.

When to Replace a Furnace Burner or Burner Assembly

A furnace burner or burner assembly may need replacement when the part is cracked, rusted, warped, clogged, or damaged beyond normal cleaning and service. Burner problems can affect flame pattern, ignition performance, heating reliability, and safe combustion inside compatible heating equipment.

Common signs of burner issues include visible corrosion, deteriorated burner ports, uneven flame, delayed ignition, flame rollout concerns, or repeated ignition failures. These symptoms can also involve related parts such as the gas valve, ignitor, flame sensor, pilot assembly, control board, or heat exchanger, so diagnosis should be confirmed before ordering a replacement burner.

Replace the burner if it is cracked, warped, or physically damaged.

Replace the burner if rust or corrosion has weakened the part.

Check for clogged or deteriorated burner ports if the flame pattern is uneven.

Confirm whether the issue involves the burner, gas valve, ignitor, flame sensor, or pilot assembly.

Use a qualified HVAC technician for burner diagnosis, fuel-system work, and gas-combustion repairs where required.

How to Choose the Right Replacement Burner

The right replacement furnace burner depends on the equipment brand, model number, fuel type, burner design, and OEM part number. Burner parts can vary by size, port pattern, mounting points, gasket requirements, and system configuration, so it is important to compare the replacement part against the original burner and manufacturer documentation before ordering.

Use the equipment label, service manual, parts diagram, or existing burner part number to confirm compatibility. If the burner is part of a fuel conversion, ignition repair, or combustion-system service, confirm the correct part with a qualified HVAC technician before checkout.

Match the OEM Part Number

Start with the OEM part number from the existing burner, equipment label, service parts list, or manufacturer diagram. A matching part number is the best way to confirm whether the burner, burner assembly, or burner kit is intended for your heating equipment.

Confirm Natural Gas or LP Compatibility

Burner parts are not always interchangeable between natural gas and LP or propane systems. Fuel type can affect the burner design, orifice requirements, conversion kit, flame pattern, and combustion setup. Always confirm the fuel type listed for the equipment and replacement part before ordering.

Check the Burner Assembly, Kit, or Pilot Burner Type

This category may include complete gas burner assemblies, individual furnace burners, pilot burners, burner kits, burner supports, gaskets, and related replacement parts. Match the exact part type, mounting points, and configuration needed for the unit instead of choosing by appearance alone.

Burner Parts and Brands Available

Furnace Part Source carries furnace burners and burner replacement parts for many heating equipment brands and system types. Available products may include gas burner assemblies, pilot burners, burner kits, LP burner kits, natural gas burner parts, burner supports, burners with gaskets, and related combustion-system components.

Brand-specific options may include burner parts from Rheem-Ruud, Lochinvar, A.O. Smith, Utica-Dunkirk, Carrier, Modine, Laars, Bradford White, Midco, Bosch HVAC, International Comfort Products, Schwank, and more. Always confirm the manufacturer, OEM part number, equipment model number, fuel type, and burner configuration before ordering.

Related Furnace Parts to Check

When replacing a furnace burner or burner assembly, it may also be helpful to inspect the parts that support ignition, flame sensing, fuel delivery, and burner control. A burner problem can sometimes appear similar to an issue with the gas valve, ignitor, flame sensor, pilot assembly, ignition control board, gasket, or heat exchanger.

Before ordering, confirm whether the burner itself is damaged or whether another furnace part is affecting ignition or flame performance. Matching the correct burner part and checking related components can help reduce repeat repairs, wrong-part orders, and installation delays.

Check the gas valve if the burner is not receiving fuel properly.

Inspect the ignitor or pilot assembly if the burner does not light.

Review the flame sensor if the burner lights but the system shuts down quickly.

Check gaskets, brackets, and mounting hardware for proper fit and sealing.

Confirm that the ignition control board and safety controls are not causing ignition interruptions.

Furnace Burner FAQs

What does a furnace burner do?

A furnace burner helps produce the controlled flame used during the heating cycle. It works with the gas valve, ignition system, combustion air, and heat exchanger to help the furnace generate heat for compatible heating equipment.

How do I know if a furnace burner needs to be replaced?

A furnace burner may need replacement if it is cracked, rusted, warped, clogged, or physically damaged. Other warning signs can include uneven flame, delayed ignition, repeated ignition failure, or burner ports that are deteriorated. A qualified HVAC technician should confirm the cause before replacement.

How do I choose the right replacement furnace burner?

Start by matching the OEM part number from the existing burner, equipment label, service manual, or parts diagram. Also confirm the equipment model number, fuel type, burner configuration, mounting points, gasket requirements, and any related kit or assembly details before ordering.

Are natural gas and LP furnace burners interchangeable?

Natural gas and LP or propane furnace burners are not always interchangeable. Fuel type can affect the burner design, orifice requirements, flame pattern, and conversion components. Always confirm the correct fuel type and manufacturer requirements before ordering a replacement burner.

Can I replace a furnace burner myself?

Furnace burners are gas-combustion components, so replacement should follow the manufacturer’s service documentation and local requirements. Use a qualified HVAC technician for fuel-system work, burner setup, combustion testing, or any repair involving gas connections.

What brands of furnace burners are available?

Furnace Part Source carries burner parts for many heating equipment brands. Available options may include Rheem-Ruud, Lochinvar, A.O. Smith, Utica-Dunkirk, Carrier, Modine, Laars, Bradford White, Midco, Bosch HVAC, International Comfort Products, Schwank, and more.

What related parts should I check when replacing a burner?

When replacing a furnace burner, check related parts such as the gas valve, ignitor, flame sensor, pilot assembly, ignition control board, gasket, mounting hardware, and heat exchanger. These components can affect ignition, flame sensing, fuel delivery, and burner operation.

Need Help Finding the Right Furnace Burner?

Before ordering a replacement furnace burner, compare the OEM part number, equipment model number, fuel type, burner configuration, mounting points, gasket requirements, and related components. Furnace burners and burner assemblies are gas-combustion parts, so fitment and installation requirements should be confirmed before checkout.

If your original burner is damaged, discontinued, or difficult to identify, contact Furnace Part Source with the brand, model number, serial number, and any part number from the existing burner or equipment label. These details can help identify the correct burner, burner assembly, pilot burner, or burner kit for compatible heating equipment.
