The B1401003S is a genuine OEM spark ignition assembly for Goodman GUE060-3 gas furnaces. This assembly generates the high-voltage spark that lights the pilot or burner and provides the flame-sense electrode that confirms ignition. A cracked ceramic insulator, eroded electrode, or fouled sensing rod leads to failed ignition, delayed light-off, or nuisance lockouts.
The OEM Goodman assembly ensures correct electrode gap, bracket geometry, and lead length for reliable first-try ignition. The generic equivalent saves money on routine replacements — confirm gap spacing and mounting orientation before installing.
Easy (2/5). Requires removing the burner-compartment access, unscrewing the old assembly, transferring the ignition lead, and setting the correct spark gap. Plan 20–30 minutes. Shut off gas and power, and verify the gap against spec before firing.
