OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GPAA42060NA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY3GPAA42060NA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that lights the burner during each heating cycle. When this component fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with a system that blows cold air or shuts down entirely after one or two ignition attempts. Replacing the spark electrode assembly is one of the most common and straightforward repairs on Carrier packaged rooftop and combination units.

• OEM Part Numbers: 48VL400002 (original, superseded) | 50HJ403022 (current OEM replacement) — factory-authorized direct substitute with identical fit and function.
• OEM vs Generic: Genuine Carrier OEM spark electrode assemblies are precision-gapped and constructed to factory specifications, ensuring consistent spark timing and reliable flame establishment. Generic alternatives often exhibit incorrect electrode gap, inferior ceramic insulators, and premature cracking under thermal cycling — risking repeated lockouts and potential gas accumulation.
• Install Difficulty: 2/5 — Shut off power and gas supply before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a flashlight. Disconnect the ignition wire harness, remove the two mounting screws, swap the electrode assembly, and reconnect. Always verify electrode gap per the unit's service manual before restoring power.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY3GPAA42060NA packaged gas/electric unit. Original part number 48VL400002 has been factory-superseded by 50HJ403022 — both numbers are fulfilled with the current production part. Verify your unit's model and serial data plate before ordering to confirm fitment. Our team is available to verify compatibility before you buy — no guesswork required.
