OEM Carrier Spark Electrode Ignitor (48VL400002) for Model PY4GPAA30040AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GPAA30040AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage spark that ignites the gas burner on each heating call. When the ignitor fails or becomes fouled, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that cycles but delivers no heat. Replacing the ignitor with the correct OEM part restores reliable ignition and prevents nuisance lockouts.

• Part Number: OEM Carrier 48VL400002 | Current superseding part: 50HJ403022 (also replaces 50HJ401430, 50HJ400608) | Factory-authorized genuine Carrier component
• OEM vs Generic: OEM spark electrodes are matched to the factory gap specification and ceramic insulator rating of your unit. Generic electrodes often use inferior ceramics that crack under thermal cycling, causing intermittent spark failure and repeat service calls.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note wire routing and connector orientation before removal. Handle ceramic insulator carefully — do not contact the electrode tip with bare hands.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.
