OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY4GPAA30060AA

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY4GPAA30060AA packaged gas/electric unit. The ignitor generates the high-voltage spark that lights the burner's gas mixture on every call for heat. When it fails, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with no heat and a fault code. Common symptoms include the unit cycling on and off repeatedly, or a hard lockout requiring a manual reset at the thermostat or board.

• Specs: L-shaped spark electrode design | Ignitor length to L: 1-3/8" | Ground length to L: 2-1/16" | Total length: 4" | Bracket length: 1-5/8" | Country of origin: USA | OEM Part Number: 48VL400002 (superseded by 50HJ403022)
• OEM vs Generic: This is a genuine Carrier factory-authorized ignitor assembly, precision-matched to the PY4GPAA30060AA's ignition module and spark gap specifications. Generic electrodes often use inferior alloys that corrode faster or produce inconsistent spark gaps, leading to nuisance lockouts and premature failure.
• Install difficulty: 2/5 — Shut off gas supply and disconnect power at the disconnect switch before beginning. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Note electrode orientation and wire routing before disconnecting. Handle the ceramic insulator carefully — do not touch the electrode tip with bare hands, as skin oils accelerate fouling.
• Warranty: 1-year OEM manufacturer's warranty against defects. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Engineered for the Carrier PY4GPAA30060AA packaged rooftop/gas-electric unit. Note that OEM part number 48VL400002 has been superseded by Carrier part number 50HJ403022 — both are the identical assembly and covered by this listing. Verify your existing electrode's L-shape profile and bracket mounting before ordering. Not sure? Our fitment team confirms compatibility before you buy.
