OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY1PNB060090AAAA

This is the genuine OEM factory-authorized spark electrode ignitor assembly for the Carrier PY1PNB060090AAAA packaged gas unit. The spark electrode ignitor is a critical ignition component responsible for generating the spark that ignites the gas burners at the start of every heating cycle. When it fails, the control board will attempt ignition, detect no flame, and lock out the unit — leaving you with a no-heat call and a fault code. Common symptoms include repeated ignition attempts with no burner flame, intermittent heating lockouts, or a visibly cracked or fouled electrode tip.

• Part Number: 48GS400168 | Also replaces PSE-CE15 | Factory Authorized Parts — genuine Carrier OEM ignitor assembly
• OEM vs Generic: OEM electrodes are manufactured to exact gap tolerance and material specifications. Off-brand electrodes frequently suffer from inconsistent spark gap, inferior ceramic insulators, and premature cracking — leading to callbacks and repeat failures.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Note ignition wire routing before disconnecting. Ceramic tip is fragile — handle with care and avoid contact with skin oils.
