OEM Carrier Spark Electrode Ignitor 48VL400002 for Model PY4GEAB36060AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY4GEAB36060AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage spark that lights the burner during each heating cycle. When it fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with no heat and a flashing fault code. A failed ignitor is one of the most common no-heat service calls on Carrier packaged rooftop and residential units.

• OEM Part Numbers: 48VL400002 (original) | Direct OEM replacement: 50HJ403022 — factory-authorized successor part, identical fit and function
• OEM vs Generic: OEM spark electrodes are manufactured to factory gap specifications and ceramic insulator ratings. Generic igniters can have inconsistent electrode gaps, leading to unreliable spark, nuisance lockouts, and shortened service life on your Carrier unit.
• Install Difficulty: 2/5 — Shut off gas and electrical power before servicing. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Disconnect the ignitor wire lead, remove the mounting screws, and swap the electrode assembly. Always verify gap and seating before restoring power.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.
