OEM Carrier Hot Surface Igniter Assembly 48GS400168 for Model PY3PNA060090AB

This OEM spark electrode igniter assembly (part# 48GS400168) is the factory-specified replacement for the Carrier PY3PNA060090AB packaged gas unit. The igniter is the first component activated in every heating cycle — it generates the intense heat required to ignite the gas burner. When it fails, the furnace will attempt ignition, fail to establish a flame, and enter a safety lockout. Common symptoms include no heat, a blinking fault code indicating ignition failure, or the system repeatedly cycling on and off without producing heat.

• Part Number: 48GS400168 | OEM Carrier Spark Electrode Ignitor Assembly | Factory-direct fitment for Carrier PY3PNA060090AB
• OEM vs Generic: This is a genuine OEM assembly manufactured to exact factory tolerances for spark gap and electrode geometry. Aftermarket igniters may have incorrect spark gap spacing or inferior ceramic insulators, leading to unreliable ignition and premature failure.
• Install Difficulty: 2/5 — Shut off gas supply and power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Photograph existing wiring and electrode position before removal. Handle ceramic insulator carefully — do not touch the electrode tip with bare hands, as oils accelerate ceramic degradation.
