The B1401003S Spark Ignition Assembly is a genuine OEM Goodman component engineered for the GUE080-4 gas furnace and compatible Goodman/Amana models. This assembly delivers the high-voltage spark that lights the main burners on every heat call, so a worn or cracked ignitor is one of the most common causes of a furnace that clicks but won't fire. Installing the factory part restores a clean, consistent ignition sequence and eliminates nuisance lockouts.
Aftermarket ignitors often use lower-grade ceramic that cracks under repeated thermal cycling and can misalign the spark gap. This OEM Goodman assembly is built to the exact gap tolerance and mounting geometry the GUE080-4 control board expects — meaning fewer failed lights, no re-gapping, and a longer service life. Choosing genuine also protects any remaining manufacturer warranty coverage.
Difficulty: Moderate. Requires shutting off gas and power, removing the burner compartment door, and swapping a single mounted assembly with a spade connector. Most experienced DIYers finish in 20–30 minutes; if you are unsure about gas-side work, have a licensed HVAC technician install it.
Ships fast and backed by our fit guarantee for the GUE080-4 platform.
