OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNAA30040AA

This OEM Carrier spark electrode ignitor (part number 48VL400002) is the factory-specified ignition component for the Carrier PY3GNAA30040AA packaged gas unit. The ignitor generates the high-voltage spark that lights the burner during each heating cycle. When the ignitor fails or becomes fouled, the burner will not light — the control board will detect the absence of ignition and lock out the unit after one or more failed attempts, leaving you with a no-heat call and a flashing fault code.

• Part Details: OEM Carrier Spark Electrode Ignitor | Part # 48VL400002 (superseded by 50HJ403022) | Genuine Factory Authorized Part | Sold individually
• OEM vs Generic: OEM spark electrodes are manufactured to exact gap, ceramic insulator length, and wire harness spec. Aftermarket igniters often ship with incorrect electrode geometry, causing intermittent spark, nuisance lockouts, and premature failure of the ignition module.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph wire routing before disconnecting the ignitor lead. Ceramic igniters are fragile — avoid contact with the electrode tip.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.
