OEM Carrier Spark Electrode Hot Surface Igniter for Model PY3PEA048115AA

This is the OEM-specified spark electrode igniter (part# 48GS400168) for the Carrier PY3PEA048115AA packaged unit. The hot surface igniter is the first component energized in every heating cycle — it heats to ignition temperature and lights the burner assembly. When the igniter fails, the furnace or packaged unit will attempt ignition, fail to establish flame, and enter a safety lockout. Common symptoms include no heat, repeated short cycling, or a visible crack in the igniter element on inspection.

• Specs: Spark electrode / hot surface igniter | OEM part# 48GS400168 | Factory-matched geometry and mounting bracket | Rated for Carrier packaged gas heating systems
• OEM vs Generic: This OEM igniter is manufactured to exact Carrier tolerances for element temperature, warm-up time, and electrode gap. Aftermarket igniters often vary in element resistance and physical dimensions, risking improper flame sensing, premature failure, or a poor seal against the burner housing.
• Install difficulty: 3/5 — Always shut off gas and 24V control power before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, work gloves (never touch the igniter element with bare hands — skin oils cause premature burnout). Photograph existing wiring and bracket orientation before removal.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
