OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PNA030040NB

This is the factory-specified OEM spark electrode ignitor (part number 48GS400168) for the Carrier PY3PNA030040NB packaged gas/electric unit. The ignitor generates the high-voltage spark that ignites the gas burner on each heating cycle. When the ignitor fails or degrades, the control board will attempt ignition, detect no flame signal, and lock out the unit — leaving you with a system that runs the inducer fan but produces no heat. Symptoms include repeated ignition attempts followed by a lockout fault code, or a visible cracked/broken electrode tip on inspection.

  • Part Number: 48GS400168 | OEM Carrier Factory Authorized Part | Spark Electrode (2-Rod) Ignitor Assembly
  • OEM vs Generic: This is a genuine Carrier OEM ignitor — factory-matched electrode geometry, gap spacing, and wire harness connector. Generic igniters often feature incorrect gap tolerances or non-OEM connectors that can cause intermittent spark, misfire, or control board faults over time.
  • Install Difficulty: 2/5 — Shut off gas supply and 24V power before servicing. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers. Photograph the wire harness routing before disconnecting. Handle the electrode carefully — avoid touching the ceramic insulator.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PY3PNA030040NB packaged heating and cooling units. Always verify the part number on your existing ignitor or unit data plate before ordering.

My furnace won’t ignite. What part is bad?

Is this igniter compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my Carrier igniter?
