OEM Carrier Spark Electrode Ignitor Assembly for Model PY1PJB048115ABAA — Part# 48GS400168

This OEM spark electrode ignitor assembly (part# 48GS400168) is the factory-specified replacement for the Carrier PY1PJB048115ABAA packaged gas unit. The ignitor assembly uses a dual-rod spark electrode design to ignite the gas burner at the start of each heating cycle. When the ignitor fails, the control board will attempt ignition, detect no flame, and send the unit into a safety lockout — resulting in a no-heat call with a flashing fault code. This is one of the most common service parts on Carrier 48GS-series gas pack equipment.

• Part Type: Spark electrode ignitor assembly | 2-rod design | Factory OEM specification | MFG# 48GS400168 | Weight: 0.07 lbs
• OEM vs Generic: This is a genuine Carrier OEM ignitor assembly — factory-matched electrode gap and ceramic insulator rating. Generic igniters may have inconsistent electrode spacing, leading to intermittent ignition failures and repeat service calls.
• Install Difficulty: 2/5 — Shut off gas and power at the disconnect before servicing. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Note the wire routing before disconnecting. Handle ceramic insulator body carefully — do not touch electrodes with bare hands as skin oils can cause premature failure.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
