OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY3PEA042090NB

This is the OEM factory-specified spark electrode ignitor assembly for the Carrier PY3PEA042090NB packaged gas unit. The 2-rod ignitor generates the high-voltage spark that ignites the gas burner on each heating call. When it fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with no heat and a blinking fault code. Replacing this ignitor with the correct OEM part restores reliable spark ignition and prevents nuisance lockouts caused by weak or misdirected spark.

• Specs: 2-rod spark electrode ignitor assembly | OEM Part# 48GS400168 | Fits Carrier 48GS-series gas pack equipment | Factory-matched electrode gap and bracket geometry
• OEM vs Generic: This is a genuine Carrier OEM ignitor assembly, engineered to exact gap spacing and rod angle specifications. Generic substitutes often feature incorrect electrode geometry, resulting in weak spark, misfires, and premature control board wear.
• Install Difficulty: 2/5 — Shut off gas and 24V power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note ceramic insulator orientation before removal — cracks in the ceramic during handling will require a new part. Do not touch the electrode rods with bare hands.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
