OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY3PEA048090AB

This is the factory OEM spark electrode ignitor assembly for the Carrier PY3PEA048090AB packaged gas unit. The ignitor is the first component to fire during every heating cycle — it generates the spark that lights the burner. When this part fails, the control board will attempt ignition, detect no flame confirmation, and lock the system out, leaving you with no heat. Common symptoms include a furnace that attempts to start, then shuts down after 5–8 seconds, repeated ignition clicking with no flame, or a system stuck in lockout mode requiring manual reset.

• Part Number: 48GS400168 | OEM Carrier Ignitor/Electrode Assembly | Also replaces PSE-CE15 | Factory-authorized Carrier replacement component
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket approximation. OEM electrodes maintain factory-spec gap geometry and ceramic insulation ratings, ensuring consistent spark and preventing premature cracking or arc-over that generic parts are prone to.
• Install Difficulty: 2/5 — Shut off gas and power at disconnect before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Photograph existing electrode orientation and wire routing before removal. The ceramic ignitor body is fragile — do not touch the tip with bare hands. Skin oils can cause premature failure.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PEA048090AB packaged gas/electric unit. This ignitor is also used across a wide range of Carrier and Bryant package units that share the same ignitor assembly specification. Always verify your existing part number on the unit's data plate or wiring diagram before ordering. Have a fitment question?
