OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PEB060090AB

This OEM spark electrode ignitor assembly (part# 48GS400168) is the factory-specified replacement for the Carrier PY2PEB060090AB packaged gas/electric unit. The ignitor assembly initiates combustion by generating a high-voltage spark across the electrode gap each time a heat call is made. When the ignitor fails or degrades, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat. Common symptoms include repeated ignition attempts with no burner light-off, a blinking fault code on the control board, or a system that runs the inducer but never fires the burners.

• OEM vs Generic: This is a genuine OEM ignitor assembly built to Carrier's exact electrode gap and ceramic insulator specifications. Generic electrodes often have inconsistent gap tolerances, leading to unreliable spark and repeat service calls. OEM ensures first-call ignition reliability.
