OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PJB048090NBAA

This OEM spark electrode ignitor assembly (part number 48GS400168) is the factory-specified replacement ignitor for the Carrier PY1PJB048090NBAA packaged heating and cooling unit. The spark electrode ignitor initiates the combustion sequence by generating a high-voltage spark that lights the burner assembly at the start of each heating cycle. When this component fails, the control board will attempt ignition, detect no flame, and enter a safety lockout — leaving you with a unit that clicks or sparks repeatedly but never fires, or one that goes completely silent after one or two ignition attempts with no heat output.

• Part Number & Type: OEM Carrier 48GS400168 | 2-Rod Spark Electrode Ignitor Assembly | Factory Authorized Parts — direct drop-in replacement, no modification required
• OEM vs Generic: OEM electrodes are manufactured to exact Carrier gap spacing and ceramic insulator specifications. Aftermarket igniters frequently exhibit improper electrode gap and inferior insulation, causing intermittent spark, premature cracking, and repeat failures within one heating season.
