OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GNA042060AB

This is the factory-specified OEM spark electrode ignitor assembly for the Carrier PY3GNA042060AB packaged gas unit. The ignitor generates the high-voltage spark that lights the burners during each heating cycle. When this component fails, the control board will attempt ignition, find no confirmed flame, and lock out the system — leaving you with a no-heat call and a blinking fault code. A failed ignitor is one of the most common causes of heating lockout on Carrier gas-pack equipment.

• OEM Part Numbers: 48VL400002 (superseded by 50HJ403022) | 48GS400168 | Factory Authorized Parts — exact factory specification, direct drop-in replacement with original wiring harness and bracket geometry
• Part Type & Specs: Spark electrode ignitor assembly | 2-rod electrode configuration | 24V control circuit compatible | Designed specifically for Carrier 48GS/PY3GNA-series packaged gas units
• OEM vs Generic: OEM ignitor assemblies use precisely gapped electrodes matched to the factory ignition module. Generic spark electrodes often suffer from inconsistent gap tolerances and inferior ceramic insulators, leading to misfires, nuisance lockouts, and premature failure — especially in outdoor packaged unit environments exposed to moisture and debris.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before starting. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers, and a phone or camera to photograph existing wiring before removal. Reconnect harness connectors fully until they click. Restore power and verify ignition on first call for heat.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse when ordered before cutoff.
