OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNA060090AA

This is the factory-authorized OEM spark electrode ignitor for the Carrier PY3GNA060090AA packaged gas unit. The ignitor generates the precisely timed electrical spark that ignites the gas burner at the start of every heat cycle. When it fails, the furnace or packaged unit will attempt ignition, fail to light, and enter a safety lockout — leaving you with no heat. Common failure signs include a furnace that clicks repeatedly but never fires, or a unit that locks out after 3 ignition attempts and requires a manual reset.

• OEM Part Numbers: 48VL400002 | Current superseding part: 50HJ403022 — exact factory-specified replacement for Carrier PY3GNA060090AA
• OEM vs Generic: This is a Factory Authorized Parts (FAP) ignitor built to Carrier's exact spark-gap, electrode material, and bracket geometry specifications. Generic igniters may vary in electrode positioning and arc timing, leading to unreliable ignition and nuisance lockouts.
• Install Difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Disconnect the ignition wire harness, unbolt the electrode bracket, swap the ignitor, and reverse. Do not touch the electrode tip with bare hands — skin oils can degrade ignition performance.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.
