OEM Carrier Spark Electrode Ignitor for Model PY3GNAA36090AA (48VL400002 / 50HJ403022)

This OEM Carrier spark electrode ignitor is the factory-authorized replacement for the Carrier PY3GNAA36090AA packaged gas unit. The spark electrode initiates combustion by generating a precisely timed high-voltage spark directly at the burner. When this component fails or degrades, the control board will attempt ignition, find no flame confirmation, and enter a safety lockout — leaving you with a blower running but no heat. Replacing the ignitor is one of the most common and cost-effective furnace repairs available.

• Specs: Spark electrode ignitor assembly | OEM part 48VL400002, superseded by 50HJ403022 | Also replaces 50HJ401430 and 50HJ400608 | Genuine Carrier factory-authorized part
• OEM vs Generic: OEM electrodes are manufactured to exact gap tolerances and insulator ratings specified by Carrier engineering. Off-brand electrodes often have inconsistent spark gap geometry, leading to intermittent ignition failures and accelerated control board wear.
• Install difficulty: 2/5 — Shut off gas supply and 120V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the ignition wire connector, remove the mounting screws, and swap the electrode. Always verify the spark gap matches OEM spec before reassembling the burner compartment.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
