OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY3GNA036090NA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY3GNA036090NA packaged unit. The ignitor generates a high-voltage spark at the burner to initiate combustion each time a heat call is made. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat. Common failure symptoms include the burner never lighting, repeated ignition attempts followed by a fault code, or a visibly cracked or corroded electrode tip.

• Specs: Spark electrode ignitor | L-shaped bracket | Ignitor length to L: 1 3/8" | Total ignitor length: 2 3/4" | Ground length: 4" total | Country of origin: USA | OEM part number 48VL400002 (superseded by 50HJ403022)
• OEM vs Generic: OEM electrodes are machined to exact gap tolerances required for reliable arc formation. Generic electrodes with inconsistent gap spacing can cause intermittent ignition failures, nuisance lockouts, and premature control board wear.
• Install difficulty: 2/5 — Shut off gas supply and 24V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a flashlight. Disconnect the ignition wire lead, remove the two mounting screws, swap the electrode, and re-gap if needed before reconnecting. Always verify ignition wire integrity before reassembly.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse.
