OEM Carrier Spark Electrode Igniter Assembly (48GS400168) for Model PY3PNA060115AB

This is the genuine OEM spark electrode igniter assembly for the Carrier PY3PNA060115AB packaged gas unit. The igniter is a critical component in your furnace's ignition sequence — it generates the high-voltage spark that lights the burner at the start of every heat cycle. When the igniter fails or degrades, your system will attempt ignition, fail to establish a flame, and enter a safety lockout. Common symptoms include a no-heat call, the system cycling on and off repeatedly, or an error code indicating failed ignition. Replacing the igniter with a factory-matched OEM unit restores reliable start-up performance and prevents repeat lockouts.
