OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAB42090NA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GEAB42090NA packaged gas/electric unit. The ignitor generates the high-voltage spark required to light the burner at every call for heat. When this component fails, the control board will attempt ignition, find no flame, and trigger a safety lockout — leaving your system dead with no heat. Common symptoms include repeated restart attempts followed by a lockout fault code, or a visible absence of spark at the burner assembly.

• OEM Part Number: 48VL400002 (Superseded by Carrier P/N 50HJ403022 — functionally identical factory replacement) | Manufacturer description: Spark Electrode Ignitor | Brand: Carrier Factory Authorized Parts™
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact OEM spark gap, ceramic insulator, and bracket specifications. Aftermarket igniters can exhibit inconsistent spark timing or incorrect electrode geometry, risking repeated misfires and accelerated control board wear.
• Install Difficulty: 2/5 — Straightforward replacement accessible through the burner compartment access panel. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Always shut off gas supply and 24V control power before removing the old ignitor. Handle the ceramic insulator carefully — do not touch the electrode tip with bare hands.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.
