OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GPAA48115NA (48VL400002 / 50HJ403022)

This OEM spark electrode ignitor assembly is the factory-authorized replacement for the Carrier PY3GPAA48115NA packaged gas unit. The ignitor generates the high-voltage spark that ignites the gas burner at the start of every heat cycle. When it fails, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with a blower running but absolutely no heat. Typical failure signs include repeated ignition attempts followed by a fault code, a cracked or fouled electrode tip, or a visibly damaged ignition cable.

• OEM Part Numbers: 48VL400002 (original, now discontinued Jan 2024) | Superseded by 50HJ403022 — identical factory fit and function | Includes spark electrode and mounting bracket
• Specs: L-shaped electrode design | Ignitor length to L: 1-3/8" | Ground length to L: 2-1/16" | Total assembly length: ~4" | Bracket length: 1-5/8" | Made in USA
• OEM vs Generic: OEM electrodes maintain factory-spec gap geometry and high-voltage insulation ratings. Aftermarket igniters often use inferior ceramic insulators that crack under thermal cycling, leading to premature arc-over and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas and power at the disconnect before beginning. Tools needed: 1/4" nut driver, needle-nose pliers, and a flat-blade screwdriver. Photograph the wire harness routing before disconnecting. Do not touch the electrode tip with bare hands — skin oils accelerate ceramic degradation. Typical tech time: 20–30 minutes.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
