OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GPAA36090NA

This OEM Carrier spark electrode ignitor (part number 48VL400002, now fulfilled by successor part 50HJ403022) is the factory-specified ignition component for the Carrier PY3GPAA36090NA packaged gas unit. The ignitor generates the high-voltage spark that lights the burner on each heating call. When it fails, the control board will attempt ignition, find no flame, and lock out — leaving you with a system that runs the inducer but produces no heat. You may see a fault code, hear repeated clicking with no ignition, or notice the unit cycling off after a few seconds.

• Part Numbers: OEM part 48VL400002 (original) | Direct OEM successor: 50HJ403022 — same factory fit and function, no modifications required
• OEM vs Generic: OEM ignitors are manufactured to exact Carrier electrode gap, ceramic body, and wire harness specifications. Generic alternatives frequently deviate from factory electrode geometry, leading to inconsistent spark and premature failure under thermal cycling stress.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before beginning. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Photograph existing wiring and electrode orientation before removal. Handle the ceramic body carefully — do not touch with bare hands, as skin oils degrade ceramic at operating temperatures.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered by 3:00 PM local time.

Compatibility: Direct OEM fit for Carrier model PY3GPAA36090NA packaged gas/electric unit. Note that original part 48VL400002 has been superseded by Carrier OEM part 50HJ403022 — both part numbers are cross-referenced and ship as the current assembly.
