OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY3GPAA42060AA

This OEM Carrier spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GPAA42060AA packaged gas/electric unit. The ignitor generates the high-voltage spark arc that ignites the gas burner on every heating call. When it fails or degrades, the control board will detect a failed ignition attempt and trigger a safety lockout — leaving you with a unit that tries to start, fails, and shuts down with no heat output. Replacing the ignitor is one of the most common and cost-effective furnace repairs available.

• Part Number: 48VL400002 (OEM Carrier Spark Electrode Ignitor Assembly) | Also superseded by Carrier part 50HJ403022 — both are factory-authorized
• OEM vs Generic: OEM electrodes are manufactured to exact gap spacing and ceramic insulator tolerances specified by Carrier engineering. Off-brand electrodes frequently suffer from inconsistent spark gap, premature ceramic cracking, and shortened service life — risking repeat no-heat calls.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, multimeter (to verify spark voltage at ignitor terminals). Always photograph wiring harness routing before disconnecting. Do not touch the ceramic electrode tip — skin oils accelerate ceramic degradation.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as a direct OEM fit for Carrier PY3GPAA42060AA packaged rooftop/gas-electric units. Note that OEM part 48VL400002 has been superseded by Carrier part number 50HJ403022 — both are genuine Carrier OEM and either is appropriate for this application. Confirm your unit's model and data plate before ordering, or contact our fitment team for verification. In stock — order now for same-day shipping.
