OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GNA060130NB

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GNA060130NB packaged rooftop gas unit. The spark electrode generates the high-voltage arc that ignites the gas burner at the start of every heat cycle. When the electrode degrades, cracks, or its gap widens from carbon buildup, the control board detects a failed ignition event and enters a safety lockout — leaving you with no heat. Common failure symptoms include repeated ignition attempts with no flame establishment, a blinking fault code indicating lockout, or a unit that runs the inducer but never fires the burner.

• OEM Part Numbers: 48VL400002 (superseded) | 48GS400168 | Direct successor: 50HJ403022 — all are factory-authorized and cross-compatible for this application
• OEM vs Generic: OEM electrodes are formed to exact gap specifications and use high-temperature ceramic insulators matched to Carrier's ignition module output voltage. Off-brand electrodes with inconsistent gap tolerances cause misfires, nuisance lockouts, and premature ignition module failure.
• Install Difficulty: 2/5 — Shut off gas and disconnect power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the HV ignition wire and ground lead, remove the one or two mounting screws, and swap the electrode. Always inspect the ignition wire boot for cracking before reinstalling.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
