It mounts at the burner and provides the high-voltage spark that lights the gas, then confirms flame so the control board keeps the gas valve open. A cracked ceramic insulator, eroded electrode, or carbon buildup shows up as no ignition, delayed light-off, or nuisance lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1401003S\u003c\/li\u003e\n\u003cli\u003eFunction: Spark ignition \u0026amp; flame-sensing electrode assembly\u003c\/li\u003e\n\u003cli\u003eCompatible Model: Goodman GUX040-3 furnace\u003c\/li\u003e\n\u003cli\u003eConstruction: Ceramic-insulated electrode with mounting bracket\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eCorrect electrode gap and positioning relative to the burner are critical for reliable light-off. This genuine Goodman assembly arrives pre-set to factory geometry. Generic electrodes often need manual bending to fit and can misfire or fail flame sensing, leading to repeat lockouts.
