OEM Carrier Spark Electrode Ignitor Assembly for Model PY3GNA036060AB

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY3GNA036060AB packaged rooftop unit. The ignitor generates the high-voltage spark that initiates combustion in the burner section at every call for heat. When the electrode fails, cracks, or becomes fouled, the unit will attempt ignition, fail to establish flame, and lock out on a fault code — leaving you with no heat. Replacing the ignitor is one of the most cost-effective repairs in packaged HVAC service.

• OEM Part Numbers: 48GS400168 (Spark Electrode Ignitor Assembly — 2 Rod) | 48VL400002 (Spark Electrode Ignitor — superseded; current replacement is 50HJ403022) | Factory Authorized Parts, Carrier Corporation
• OEM vs Generic: OEM electrode assemblies are precision-gapped and manufactured to exact ceramic and alloy specifications. Off-brand electrodes often suffer from incorrect gap spacing and inferior ceramic insulators, leading to misfires, premature cracking, and repeated lockouts.
• Install Difficulty: 2/5 — Turn off all power and gas before beginning. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers, and a flashlight. Note wire lead routing before disconnecting. Electrode tip is fragile — handle by the ceramic body only and avoid touching the rod.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse in original factory packaging.

Compatibility: Designed for the Carrier PY3GNA036060AB packaged rooftop gas/electric unit. Always verify your unit's existing electrode configuration (single-rod vs. 2-rod) and wire harness connector before ordering. If your unit shows OEM part 48VL400002 on the service label, order 48GS400168 or its current supersession 50HJ403022 as the active replacement. Questions about fitment? Our HVAC parts specialists verify compatibility before you order — no guesswork.
