OEM Carrier Spark Electrode Ignitor (48VL400002) for Model PY3GNA060115NA

This OEM Carrier spark electrode ignitor is the factory-specified replacement for the Carrier PY3GNA060115NA packaged gas unit. The ignitor is a critical component in the heating sequence: upon a call for heat, the control board energizes the ignitor to generate the spark or surface heat needed to light the main burners. When the ignitor fails, the furnace will attempt ignition, fail to establish flame, and enter a safety lockout — leaving you with no heat. Common symptoms include the system cycling on and off repeatedly, a clicking sound with no ignition, or a fault code on the control board indicating ignition failure.

• OEM Part Numbers: 48VL400002 (original) | Current active replacement: 50HJ403022 — both are factory-authorized Carrier ignitor assemblies
• OEM vs Generic: OEM ignitors are precision-manufactured to Carrier's exact spark gap, electrode geometry, and wire harness specifications. Generic igniters may have inconsistent spark output or mismatched connectors, leading to nuisance lockouts or premature failure.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before starting. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify electrode resistance. Always photograph the wiring harness routing before disconnecting. Handle the ceramic ignitor body carefully — do not touch the element with bare hands.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PY3GNA060115NA packaged gas/electric unit.
