OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PNA024040NA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PNA024040NA packaged unit. The ignitor is responsible for initiating combustion in the heat section of your packaged gas system — when it fails, the control board will attempt ignition, find no flame, and lock the unit out on a fault code. Common symptoms include a no-heat call, repeated short cycling during startup, or a hard lockout with a flashing fault LED on the control board. Replacing the ignitor with the correct OEM assembly restores reliable ignition and clears nuisance lockouts caused by weak or failed electrodes.

• OEM Part Number: 48GS400168 | Manufacturer description: Spark Electrode Ignitor Assembly | Replaces PSE-CE15 | Factory Authorized Carrier Part
• OEM vs Generic: This genuine Carrier OEM ignitor is manufactured to exact factory gap, ceramic, and electrode specifications. Generic electrodes often have inconsistent spark gaps and inferior ceramic insulators, increasing the risk of misfires and premature cracking.
• Install Difficulty: 2/5 — Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Carefully note wire routing and ceramic bracket orientation before removal — the ceramic insulator is fragile and should never be forced.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
