OEM Carrier Spark Electrode Ignitor for Model PY3GPAA48130AA (Part# 48VL400002)

This is the OEM factory-specified spark electrode ignitor for the Carrier PY3GPAA48130AA packaged gas unit. The spark electrode ignitor generates the high-voltage spark that lights the gas burner at the start of every heating cycle. When this component fails or becomes fouled, the control board will attempt ignition — detect no flame — and lock out the unit, leaving you with no heat. Common failure symptoms include repeated ignition attempts with no burner light-off, hard lockout fault codes, or intermittent heating that stops mid-cycle.

• Part Specifications: OEM Carrier spark electrode ignitor | Part# 48VL400002 (superseded by 50HJ403022) | Factory-matched geometry and gap tolerance for reliable spark generation | Made in the USA
• OEM vs Generic: OEM electrodes maintain the exact tip-to-ground gap and ceramic insulator grade specified by Carrier engineering. Off-brand electrodes often use inferior ceramics that crack under thermal cycling, causing intermittent misfires and premature failure.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a flashlight. Note wire harness routing before disconnecting. Do not touch the ceramic insulator with bare hands — skin oils degrade the insulator and cause arcing.
• Warranty & Shipping: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse — order today, heat tomorrow.

Compatibility: Designed and factory-matched for the Carrier PY3GPAA48130AA packaged gas/electric unit. Note that OEM part number 48VL400002 has been superseded by 50HJ403022 — both are fully interchangeable and either may be shipped depending on current inventory.
