OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY3PEA048130NA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY3PEA048130NA packaged gas unit. The ignitor assembly initiates combustion by generating a high-voltage spark across two electrodes to light the burner. When this component fails, the system will attempt an ignition cycle, fail to establish flame, and enter a lockout condition — leaving you with no heat. Common symptoms include repeated ignition attempts with no burner light-off, error codes indicating ignition failure, or a unit that cycles on the inducer but never fires the burners.

• Part Number: 48GS400168 | 2-Rod Spark Electrode Ignitor/Electrode Assembly | Factory-authorized OEM replacement | Manufacturer: Carrier
• OEM vs Generic: This is a genuine Carrier factory-authorized part, ensuring exact electrode gap spacing, ceramic insulator rating, and lead wire length. Aftermarket igniters often have inconsistent gap tolerances that cause nuisance lockouts or premature failure, costing more in callbacks.
• Install Difficulty: 2/5 — Turn off gas supply and 24V power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify spark output. Photograph existing wiring and electrode orientation before disconnecting. Ceramic insulator is fragile — handle with care and avoid touching electrode tips.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered as the direct OEM replacement for the Carrier PY3PEA048130NA packaged rooftop gas unit. Always verify your unit's data plate and existing part number before ordering to confirm fitment.
