Goodman B1401003S Spark Ignition Assembly

The B1401003S is the genuine OEM spark ignition electrode assembly for the Goodman GUE100-5 gas furnace. This assembly generates the high-voltage spark that lights the burner and, on many configurations, provides flame rectification back to the control board. When the electrode gap drifts, the ceramic insulator cracks, or the tip erodes, the furnace may fail to light, ignite with a delayed 'poof,' or lock out on failed flame sense.

Specifications

Part number: B1401003S
Function: Spark ignition electrode / igniter assembly
Compatibility: Goodman GUE100-5 gas furnace
Equipment type: Furnace
Condition: New OEM replacement

OEM vs. Generic

The OEM B1401003S ships with the correct electrode gap, bracket, and lead length pre-set for the GUE100-5 burner, so it lights cleanly and senses flame reliably out of the box. Generic igniters often need gap adjustment and can cause hard starts or nuisance lockouts. For dependable ignition, the OEM assembly is the safe choice.

Installation

Difficulty: Intermediate (3/5). Requires removing the burner access panel, unclipping the electrode lead, and unbolting the assembly from the burner. Verify the spark gap and lead routing on reinstall. Shut off gas and power first; qualified technician recommended.
