OEM Carrier Spark Electrode Ignitor Assembly 48VL400002 for Model PY3GNA024040NA

This is the genuine OEM Carrier spark electrode ignitor assembly — originally catalogued as 48VL400002 and fulfilled by the current factory-authorized successor part 50HJ403022 — designed as the direct replacement for the Carrier PY3GNA024040NA packaged unit. The spark electrode ignitor is responsible for generating the high-voltage spark that lights the gas burner at the start of every heat call. When the ignitor fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that runs the inducer and then shuts down with no heat produced.

• OEM Part Numbers: 48VL400002 (original) | 50HJ403022 (factory authorized successor) — direct form-fit-function replacement, no modifications required
• Ignitor Specs: L-shaped spark electrode | Ignitor length to L: 1-3/8" | Total length: 2-3/4" | Ground style: L | Bracket length: 1-5/8" | Country of Origin: USA
• OEM vs Generic: OEM spark electrodes are manufactured to exact gap spacing and ceramic insulator tolerances. Off-brand electrodes can arc inconsistently, cause nuisance lockouts, and accelerate control board wear from repeated retries.
• Install Difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the ignition wire, remove the mounting screws, swap the electrode, and reconnect. Always verify gap per the unit's service manual before restoring power.
• Warranty: 1-year OEM factory warranty on defects in materials and workmanship. Ships same business day from our warehouse.
