OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PNB042060AA

This OEM spark electrode ignitor is the factory-specified replacement for the Carrier PY2PNB042060AA packaged gas unit. The ignitor generates the high-voltage spark arc that lights the gas burner on each call for heat. When this component fails, the system will attempt ignition, fail to establish flame, and enter a hard lockout — leaving you with no heat and a blinking fault code on the control board. Replacing it with the correct OEM part ensures proper spark timing and gap alignment as designed by Carrier.

• Part Specs: OEM Part# 48GS400168 | 2-rod spark electrode assembly | Factory-authorized replacement | Direct plug-and-play fitment for Carrier 48GS-series packaged gas units
• OEM vs Generic: OEM electrodes maintain the precise rod gap and ceramic insulator rating specified by Carrier engineering. Generic igniters often have inconsistent rod spacing and lower-grade ceramic insulators, increasing the risk of misfires, nuisance lockouts, and premature failure.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before servicing. Tools needed: 1/4" or 5/16" nut driver, flathead screwdriver, needle-nose pliers. Photograph harness connector orientation before disconnecting. Reinstall per factory torque spec — overtightening can crack the ceramic insulator.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our stocked warehouse.
