OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Payne PY3PNA060130AA Packaged Rooftop Unit

This is the OEM-spec spark electrode ignitor assembly (part# 48GS400168) for the Carrier/Payne PY3PNA060130AA single-packaged gas furnace/air conditioner rooftop unit. The ignitor assembly generates the high-voltage spark that ignites the burners during each heating cycle. When the electrode fails, the induced-draft motor will run and the gas valve will open — but with no ignition event, the control board will lock out after the trial-for-ignition period, resulting in a no-heat fault. Common symptoms include a blinking fault code on the IGC board, repeated restart attempts with no flame, or a cracked/fouled electrode visible on inspection.

• OEM Part Number: 48GS400168 | Description: Spark Electrode Ignitor Assembly (2-Rod) | Weight: 0.07 lbs | Factory-direct replacement — no modifications required
• OEM vs Generic: This OEM assembly matches factory electrode gap, ceramic insulator rating, and bracket geometry exactly. Generic igniters often have inconsistent electrode gaps or lower-grade ceramics, leading to weak spark and repeat ignition failures — especially critical in rooftop packaged units exposed to weather extremes.
• Install Difficulty: 2/5 — Straightforward swap accessible through the burner/heating section access panel. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Always shut off gas and 24V control power before servicing. Inspect ceramic insulators for cracks before re-energizing.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier/Payne PY3PNA060130AA 5-ton, 130,000 BTU single-packaged rooftop gas/electric unit. Always verify your unit's full model number and data plate before ordering. Our parts specialists can confirm fitment — contact us before you buy if you have any questions.
