OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PPB042060AB

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY2PPB042060AB packaged gas/electric unit. The ignitor generates 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 its inducer but never fires the burner. You may also see a blinking fault code on the control board indicating an ignition failure.

• Specs: Dual-rod spark electrode assembly | OEM part number 48GS400168 | Factory-matched electrode gap and ceramic insulator rating | Direct drop-in replacement — no modification required
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part, built to exact ceramic and electrode-gap tolerances. Aftermarket igniters frequently use inferior ceramics that crack under thermal cycling, leading to repeat failures within one heating season.
• Install difficulty: 2/5 — Shut off gas and power at the disconnect before starting. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Disconnect the ignitor harness, remove the mounting screw(s), and swap in the new assembly. Avoid touching the electrode tips with bare hands — skin oils can cause premature ceramic degradation.
• Warranty: 1-year OEM factory warranty. Orders placed before our same-business-day cutoff ship from our warehouse today.
