OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PNB060130AB

This OEM spark electrode ignitor assembly (part# 48GS400168) is the factory-specified replacement for the Carrier PY2PNB060130AB packaged gas unit. The dual-rod spark electrode assembly generates the high-voltage arc that ignites the gas burners on each call for heat. When this component fails, the inducer motor will run and gas valve will open, but the burners won't light — triggering a hard lockout fault after 1–3 ignition attempts. Homeowners and technicians typically recognize the symptom as a unit that "tries" to start, then shuts down with a blinking fault code indicating ignition failure.

• OEM Part Number: 48GS400168 | 2-rod spark electrode ignitor assembly | Factory-matched electrode gap and ceramic insulator rating
• OEM vs Generic: This is a genuine Carrier OEM assembly, ensuring exact electrode geometry, rod spacing, and insulator dielectric strength. Aftermarket igniters frequently suffer from electrode gap drift, premature ceramic cracking, and mismatched lead wire length — all of which cause repeat no-light faults.
• Install Difficulty: 2/5 — Shut off gas supply and 24V power at the disconnect before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and a flashlight. Photograph the original wiring and lead routing before disconnecting. The assembly typically mounts with one or two screws to the burner box; swap leads one at a time to avoid reversal. Average technician time: 20–30 minutes.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered for the Carrier PY2PNB060130AB packaged gas unit. Always verify your unit's data plate and existing ignitor configuration (2-rod spark electrode) before ordering.
