OEM Carrier Spark Electrode Ignitor (48GS400168) for Model PY3PEA036090AA

This is the genuine OEM Carrier spark electrode ignitor assembly (part number 48GS400168), factory-specified for the Carrier PY3PEA036090AA packaged gas/electric unit. The spark electrode ignitor generates the high-voltage arc that ignites the gas burner during each heating cycle. When this component fails, the unit will attempt ignition, fail to light the burner, and enter a safety lockout — leaving you with no heat. Common symptoms include repeated ignition attempts with clicking, a flashing fault code on the control board, or a complete no-heat condition.

• Part Specs: OEM Carrier spark electrode ignitor assembly | Part No. 48GS400168 | Replaces PSE-CE15 | Factory-matched electrode geometry and gap for reliable arc initiation
• OEM vs Generic: This OEM ignitor is manufactured to Carrier's exact electrode tip angle, gap, and wire lead length. Generic electrodes frequently feature imprecise gaps or mismatched lead lengths, causing intermittent spark failures or premature cracking at the ceramic insulator.
• Install Difficulty: 2/5 — Shut off gas and power at the disconnect before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Photograph all wire connections before removing the old electrode. Handle the ceramic insulator carefully — it is fragile and will crack if dropped or over-tightened.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
