OEM Carrier Spark Electrode Igniter (48GS400168) for Model PY2PPB042060NB

This OEM spark electrode igniter is the factory-specified replacement for the Carrier PY2PPB042060NB packaged heating and cooling unit. The igniter generates the high-voltage spark required to light the burner assembly during each heating cycle. When it fails or degrades, the control board will typically complete one or more ignition attempts and then go into lockout, leaving you with a no-heat call and a fault code on the board. Cracked insulators, carbon tracking, or a broken electrode tip are the most common failure signatures.

• Specs: OEM Part Number 48GS400168 | Spark Electrode Ignitor | Factory-matched fit, form, and function for the Carrier PY2PPB042060NB packaged unit | Correct electrode gap and insulator geometry pre-set at the factory
• OEM vs Generic: This OEM igniter ships with the exact electrode gap, ceramic insulator grade, and bracket geometry specified by Carrier engineering. Aftermarket igniters frequently use inferior ceramics that crack under thermal cycling, causing repeat service calls within a single heating season.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect 24V control power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a continuity tester. Photograph existing wiring and electrode orientation before removal. Handle the ceramic insulator with care — skin oils can cause premature cracking.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders placed before cutoff ship same business day from our warehouse.
