OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GNA048130NB

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GNA048130NB gas packaged rooftop unit. The spark electrode generates the high-voltage arc that ignites the burner assembly on each call for heat. When this component fails or becomes fouled with carbon deposits or cracks in the ceramic insulator, the control board will attempt ignition, fail to prove flame, and lock out the unit — leaving you with a packaged unit that blows only cold air. Replacing the ignitor is typically the first corrective step when diagnostics show repeated ignition lockout fault codes.

• OEM Part Numbers: 48VL400002 (superseded) | 48GS400168 (current active replacement) | Also cross-references 50HJ403022 — verify with your unit's data plate before ordering.
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part. OEM electrodes are manufactured to exact ceramic grade, gap spacing, and wire harness specifications. Aftermarket electrodes frequently mis-match electrode gap or use inferior ceramic, causing intermittent spark, premature cracking, and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and a flat-head screwdriver. Disconnect the high-voltage ignitor wire carefully to avoid cracking the ceramic boot. Do not touch the ceramic electrode tip — skin oils accelerate cracking under heat cycling.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
