This assembly generates the high-voltage spark that lights the pilot or main burner on each heating call. Over time the electrode gap widens, the ceramic insulator cracks, or the spark rod corrodes — resulting in delayed ignition, repeated lockouts, or a furnace that won't fire at all. Installing a fresh OEM ignition assembly restores fast, dependable light-off and eliminates nuisance no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1401003S\u003c\/li\u003e\n\u003cli\u003ePart Type: Spark Ignition Assembly \/ Ignitor Electrode\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GUE120-5\u003c\/li\u003e\n\u003cli\u003eFunction: Spark-to-pilot \/ direct spark ignition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman assembly arrives with the correct electrode gap, mounting bracket, and lead length pre-set for the GUE120-5 burner.
