OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PPB030040AB

This is the OEM factory-specified spark electrode ignitor assembly (part number 48GS400168) for the Carrier PY2PPB030040AB packaged gas unit. The spark electrode ignitor generates the high-voltage spark that ignites the gas burner at the start of each heat cycle. When this component fails or becomes fouled with carbon deposits, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with no heat. Common failure symptoms include repeated ignition attempts with no burner light-off, intermittent heating, or a hard lockout fault code on the control board.

• Part Number: 48GS400168 | Replaces PSE-CE15 | OEM Carrier Ignitor/Electrode Assembly — factory-matched fit and spark gap specification
• OEM vs Generic: OEM electrodes are manufactured to exact Carrier spark gap and ceramic insulator tolerances. Off-brand electrodes frequently cause misfires, nuisance lockouts, and premature ceramic cracking that can damage the heat exchanger area.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before service. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph or label the ignition wire connection before removal. Ceramic tip is fragile — handle with care and avoid contact with oils from bare hands.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
