OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PNA024040AB

This is the OEM factory-specified Spark Electrode Ignitor Assembly (part number 48GS400168) for the Carrier PY3PNA024040AB packaged gas unit. The spark electrode ignitor is responsible for creating the high-voltage spark that ignites the gas burner at the start of every heat cycle. When this component fails or degrades, the control board will attempt ignition, detect no flame, and trigger a safety lockout — leaving you with a unit that calls for heat but produces none. Common symptoms include repeated ignition attempts followed by fault codes, or a complete no-heat condition even with confirmed gas supply and a functioning thermostat.

• Part Specs: OEM Carrier Spark Electrode Ignitor Assembly | Part No. 48GS400168 | Replaces PSE-CE15 | Factory-matched geometry and gap for reliable arc and flame establishment
• OEM vs Generic: This is a genuine Carrier OEM assembly — not an aftermarket substitute. OEM electrodes maintain the precise tip geometry and ceramic insulation rating required for consistent spark performance. Generic electrodes can misfire or crack prematurely under thermal cycling.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a torque-conscious hand — ceramic insulators are fragile. Photograph wiring and electrode orientation before removal. Reconnect ignition wire securely to avoid intermittent spark.
• Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.
