OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY1PPB048090ABAA

This is the factory OEM spark electrode ignitor assembly (part# 48GS400168), the direct-fit replacement for the Carrier PY1PPB048090ABAA packaged gas/electric unit. The ignitor assembly generates the high-voltage spark that lights the gas burner during each heating cycle. When the electrode fails, the control board detects no ignition event and enters a safety lockout — leaving you with a system that attempts to start, fails after 2–3 tries, and shuts down entirely until reset. This is one of the most common no-heat service calls on this platform.

• Part Specs: 2-rod spark electrode ignitor assembly | OEM part number 48GS400168 | Replaces Carrier Ignitor/Electrode Assembly | Lightweight at approx. 0.07 lbs | Factory-matched ceramic insulator and electrode gap
• OEM vs Generic: OEM electrodes are manufactured to exact gap, ceramic grade, and rod geometry specifications. Generic igniters may have inconsistent electrode spacing or inferior ceramic insulation, leading to misfires or premature cracking under repeated thermal cycling.
• Install Difficulty: 2/5 — Straightforward replacement. Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" nut driver, needle-nose pliers, and a phone camera to photograph wire routing before disconnecting the high-voltage ignition cable. Most techs complete this swap in under 20 minutes.
• Warranty: 1-year OEM factory warranty on parts defects. Ships same business day from our warehouse when ordered before cutoff.
