OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PPA048115NA

This is the genuine OEM Carrier spark electrode ignitor assembly, part number 48GS400168, factory-specified for the Carrier PY3PPA048115NA packaged unit. The spark electrode ignitor is responsible for generating the high-voltage spark that lights the burner on every call for heat. When this component fails, the control board will detect no ignition confirmation, trigger a lockout sequence, and the unit will deliver no heat. Common failure symptoms include repeated ignition attempts with no flame, hard lockout fault codes, or a visibly cracked or fouled electrode tip.

• Part Number: 48GS400168 | OEM Carrier Ignitor/Electrode Assembly | Factory-authorized replacement — direct drop-in fit, no modifications required
• OEM vs Generic: OEM electrodes are manufactured to exact gap spacing, ceramic insulator grade, and wire harness length specified by Carrier engineering. Aftermarket igniters often use inferior ceramics that crack under thermal stress, leading to repeat failures and potential mis-fires.
• Install Difficulty: 2/5 — Shut off gas supply and 24V control power before beginning. Disconnect the ignition wire connector, remove the single mounting screw, and swap the electrode. Tools needed: flat-head screwdriver, 1/4" nut driver. Verify electrode gap and orientation match original before restoring power.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
