OEM Carrier Hot Surface Igniter 48GS400168 for Model PY2PPB048115AA

This is the factory OEM hot surface igniter (spark electrode ignitor) specified for the Carrier PY2PPB048115AA packaged gas/electric unit. The igniter is the critical first step in every heating cycle — it glows white-hot to ignite the gas burner within seconds of a heat call. When it fails, the control board detects no flame establishment and triggers a safety lockout, leaving you with a system that attempts ignition, fails, and locks out — typically after 3 retries. Replacing this part with the correct OEM unit restores reliable, factory-spec ignition timing and longevity.

• Specs: OEM Part No. 48GS400168 | Type: Spark Electrode / Hot Surface Igniter | Factory-matched mounting geometry and lead length for PY2PPB048115AA | Rated for the burner assembly voltage on this model series
• OEM vs Generic: The OEM igniter is manufactured to exact Carrier tolerances for element resistance, tip geometry, and ceramic insulator rating. Generic igniters often vary in resistance and physical profile, leading to mis-fires, premature cracking, and repeat service calls — OEM is always the recommended choice.
• Install Difficulty: 2/5 — Turn off gas supply and 24V power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle the igniter element only by its ceramic body — skin oils will cause premature cracking and failure. Photograph existing wiring before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM ship same business day from our warehouse.
