OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAA36060AA

This OEM spark electrode ignitor (part number 48VL400002, superseded by 50HJ403022) is the factory-specified replacement for the Carrier PY4GEAA36060AA packaged unit. The spark electrode ignitor generates the high-voltage electrical arc that ignites the burner assembly during each heating cycle. When the ignitor fails or becomes fouled, the control board will attempt ignition, receive no flame confirmation, and lock out the system — leaving you with a unit that runs the inducer but delivers no heat. You may also notice repeated ignition attempts followed by a fault code on the control board.

• Part Specs: OEM part number 48VL400002 | Superseded/replaced by Carrier P/N 50HJ403022 | Spark electrode-style ignition | Factory-matched fit and geometry for Carrier PY4G-series packaged units
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM electrodes maintain exact spark-gap geometry and ceramic insulator ratings. Aftermarket igniters may have incorrect gap spacing or inferior ceramic, leading to intermittent ignition and premature re-failure.
• Install Difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify spark module output. Always document wire routing and connector orientation before removal. Handle the ceramic electrode body carefully — do not apply pressure to the insulator.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.
