OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PNB024060AB

This OEM spark electrode ignitor assembly is the factory-specified replacement for the Carrier PY2PNB024060AB packaged gas unit. The ignitor assembly generates the high-voltage spark that ignites the gas burner at the start of every heating cycle. When this component fails, the unit will attempt ignition, fail to establish flame, and enter a safety lockout — leaving your system with no heat and an ignition fault code on the control board.

• Specs: 2-Rod spark electrode ignitor assembly | OEM part number 48GS400168 | Compatible with Carrier 48GS-series gas pack platforms | Pair with ignition wire 50HJ403024 (sold separately) for a complete ignition system service
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact gap spacing and ceramic insulator tolerances. Off-brand electrodes often ship with incorrect rod geometry, leading to intermittent spark and repeat lockouts.
• Install difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Photograph ignition wire routing before disconnecting. Confirm proper rod gap per unit service manual after installation.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
