OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY1PEB036090AAAA

This is the factory OEM spark electrode ignitor assembly for the Carrier PY1PEB036090AAAA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that ignites the burner on each heating call. When this component fails, the control board will attempt ignition, detect no flame, and lock out — leaving you with a system that attempts to start, then shuts down with a no-heat fault code. Replacing the ignitor assembly with the correct OEM part restores reliable ignition and prevents nuisance lockouts.

• OEM Part Number: 48GS400168 | 2-rod spark electrode design | Factory-matched ignition gap and ceramic insulator | Direct drop-in fit for Carrier 48GS-series packaged units
• OEM vs Generic: This is a genuine Carrier factory-authorized part — not an aftermarket substitute. OEM electrodes maintain the precise spark gap and ceramic insulator rating required by the control board's ignition module, reducing the risk of repeated lockouts or premature control board failure.
• Install difficulty: 2/5 — Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Disconnect the high-voltage ignition wire and ground lead, remove the mounting screws, swap the electrode, and verify gap before reconnecting. Always confirm gas is fully off before working near the burner assembly.
• Warranty & Shipping: Backed by Carrier's OEM factory warranty. In stock and ships same business day from our warehouse — order before cutoff for fastest delivery.
