OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PEA060090NA

This OEM spark electrode ignitor assembly (part number 48GS400168) is the factory-specified replacement for Carrier model PY3PEA060090NA packaged heating units. The ignitor initiates combustion by generating the high-voltage spark that lights the burner on each call for heat. When this component fails, the control board will attempt ignition, detect no flame, and lock out the system — leaving you with a unit that runs through a startup sequence but produces no heat. Repeated lockout faults on your thermostat or control board display are the most common sign of ignitor failure.

• OEM Part Number: 48GS400168 | Manufacturer description: Spark Electrode Ignitor Assembly | Replaces PSE-CE15 | Factory-authorized Carrier part
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact electrical and ceramic specifications. Generic igniters often vary in electrode gap, tip geometry, and wire harness length — risking misfire, poor flame establishment, and premature control board faults.
• Install Difficulty: 2/5 — Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers. Note electrode orientation and wire routing before disconnecting. Handle ceramic tip carefully — never touch with bare hands, as skin oils cause premature failure.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
