OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY1PEB048090NBAA — Part# 48GS400168

This is the OEM factory-specified spark electrode ignitor for the Carrier PY1PEB048090NBAA packaged gas/electric unit. The hot surface igniter is the critical first step in every heating cycle — it glows to ignition temperature within seconds to light the gas burner. When this component fails, the control board will attempt ignition, find no flame confirmation, and lock out the system, resulting in a no-heat call. Common failure symptoms include repeated ignition lockouts, a cracked or broken igniter element, or a furnace that attempts to start but never fires.

• OEM vs Generic: This is a genuine Carrier OEM igniter — not an aftermarket substitute. OEM igniters are manufactured to exact resistance, temperature, and dimensional tolerances. Generic igniters may have inconsistent warm-up times or improper tip geometry, causing misfire or premature cracking.
• Install difficulty: 2/5 — Shut off gas supply and 120V power before servicing. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Handle the igniter element with care — skin oils degrade ceramic materials. Do not touch the element with bare hands.
