OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PNB042060AB

This OEM spark electrode ignitor assembly is the factory-specified replacement part for the Carrier PY2PNB042060AB packaged gas unit. The ignitor assembly generates the high-voltage spark required to light the burner at the start of each heat cycle. When the electrode fails or cracks, the unit will attempt ignition, fail to establish a flame, and lock out — leaving you with no heat. Common symptoms include repeated ignition attempts with no burner light-off, a flashing fault code on the control board, or a system that runs the inducer but never advances to the heating stage.

• Part Number: 48GS400168 | OEM Carrier Spark Electrode Ignitor Assembly | 2-rod electrode configuration | Factory-matched to Carrier 48GS series gas pack burner assemblies
• OEM vs Generic: This is a genuine OEM Carrier part engineered to exact gap, ceramic insulator, and bracket specifications. Off-brand electrodes frequently suffer from incorrect spark gap, inferior ceramic insulation, and premature cracking — leading to repeat failures and potential control board damage.
• Install Difficulty: 2/5 — Turn off gas supply and disconnect power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Disconnect the high-voltage ignition cable, remove the mounting bracket screws, swap the electrode assembly, and reconnect. Always verify spark gap is intact before reassembly.
• Warranty: 1-year OEM factory warranty against defects. Orders ship same business day from our warehouse when placed before cutoff.
