OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNA060115AA

This is the factory-specified OEM spark electrode ignitor for the Carrier PY3GNA060115AA packaged gas unit. The spark electrode ignitor is a critical component in the burner ignition sequence — it generates the high-voltage spark that ignites the gas at the burner assembly during each call for heat. When this part fails, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with a furnace that runs the inducer and clicks repeatedly but produces no heat. In some cases, a cracked or fouled electrode will cause intermittent ignition failures and nuisance lockouts before failing completely.

• Specs: Spark electrode ignitor assembly | OEM part number 48VL400002 | Superseded by Carrier part 50HJ403022 | Factory-matched electrode gap and ceramic insulator | Includes mounting hardware and lead wire
• OEM vs Generic: OEM electrodes maintain precise factory spark gap tolerances and use high-temperature ceramic insulators rated for the exact operating environment of the PY3GNA060115AA burner assembly. Off-brand electrodes may present incorrect gap dimensions or inferior ceramics that crack prematurely under thermal cycling.
• Install difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a flashlight. Photograph the existing electrode orientation and wire routing before removal. Avoid touching the ceramic insulator body — skin oils can cause cracking at high temperatures.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse on orders placed before cutoff.

Compatibility: Designed for the Carrier PY3GNA060115AA packaged gas/electric unit. Note that OEM part 48VL400002 has been superseded by Carrier part number 50HJ403022 — both are genuine Carrier OEM parts and are direct replacements for this application.
