OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GPAA60115AA

This is the factory-authorized OEM spark electrode ignitor (part number 48VL400002), the direct replacement for the Carrier PY3GPAA60115AA packaged gas unit. The spark electrode generates the high-voltage ignition arc that lights the gas burner on each call for heat. When this component fails or becomes fouled, the control board will attempt ignition, fail to prove flame, and trigger a safety lockout — leaving you with a blower running but no heat. A cracked ceramic insulator, corroded electrode tip, or degraded ground strap are the most common causes of failure.

• Part Number: 48VL400002 (superseded by 50HJ403022) | OEM Factory Authorized Part | Genuine Carrier ignitor assembly
• OEM vs Generic: OEM electrodes are manufactured to exact gap, ceramic grade, and bracket geometry specifications. Aftermarket igniters frequently ship with incorrect tip spacing or inferior ceramics, leading to nuisance lockouts and premature re-failure.
• Install Difficulty: 2/5 — Turn off gas supply and 24V control power before starting. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers, smartphone to photograph wiring connections. The electrode mounts to the burner assembly with one or two screws; note the precise tip-to-ground gap before removal and match on installation.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as the direct OEM replacement for the Carrier PY3GPAA60115AA packaged gas/electric rooftop unit. Note that OEM part 48VL400002 has been superseded by Carrier part number 50HJ403022 — both are genuine Carrier components and either fulfills the factory specification. Verify your unit's data plate and wiring configuration before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
