Furnace Pilot Burners

A pilot burner provides the ignition source that lights the main burner on many gas furnaces, boilers, and water heaters. Pilot burners may work independently or in combination with a thermocouple, spark igniter, or flame sensor as part of a complete pilot assembly.

Furnace Part Source carries a range of pilot burners and pilot assemblies for residential and light-commercial heating equipment, including natural gas and LP propane configurations.

Common Pilot Burner Parts We Carry

Common replacement parts in this category include:

Natural gas and LP pilot burners matched to the equipment's fuel type.
Pilot assemblies that combine the burner with a thermocouple, sensor, or spark electrode.
Spark ignition pilot assemblies for equipment using electronic ignition.
Mounting brackets and assembly hardware used to secure the pilot burner in place.

How to Find the Right Pilot Burner

Before ordering, check the equipment data plate and the existing pilot burner for a part or reorder number. The size and shape of the pilot burner can vary based on fuel type, so natural gas and LP burners are generally not interchangeable.

For best fit, compare:

Original pilot burner part number
Fuel type, such as natural gas or LP propane
Mounting bracket and assembly style
Equipment model, such as furnace, boiler, or water heater

If you are replacing the pilot burner along with other worn components, such as a thermocouple or flame sensor, you may need to service other parts of the assembly at the same time.

Pilot Burner FAQs

Are natural gas and LP pilot burners interchangeable?

No. Natural gas and LP propane pilot burners are sized differently for their fuel type and are not interchangeable without a proper conversion kit, if available from the manufacturer.

What is included in a pilot assembly?

A pilot assembly typically includes the pilot burner along with a thermocouple, flame sensor, or spark electrode, and may include mounting hardware or tubing depending on the equipment.

What are signs of a failing pilot burner?

Common signs include the pilot flame failing to stay lit, a weak or discolored flame, or the main burner failing to ignite even when the pilot is lit.

Can I replace just the pilot burner without the full assembly?

In some cases, yes, if the burner is sold separately from the thermocouple or sensor. Check the product listing or contact us to confirm what is included before ordering.
