OEM Carrier Spark Electrode Ignitor Assembly (48GS400168) for Model PY1PPB036090ABAA

This is the OEM factory-specified spark electrode ignitor assembly for the Carrier PY1PPB036090ABAA packaged gas unit. The ignitor's 2-rod electrode assembly generates the spark that lights the burner on each call for heat. When this component fails or degrades, the control board will attempt ignition, detect no flame, and trigger a safety lockout — leaving your system with no heat. Common failure symptoms include a furnace that attempts to start and then locks out, repeated ignition trial errors on the control board, or a visible cracked or corroded electrode tip.

• Part Number: 48GS400168 | OEM Carrier Spark Electrode Ignitor/Electrode Assembly | 2-Rod Configuration | Factory-direct fitment for PY1PPB036090ABAA
• OEM vs Generic: This is a genuine OEM Carrier ignitor — not an aftermarket substitute. OEM electrodes are manufactured to exact gap spacing and ceramic insulator specifications. Generic igniters often feature inconsistent electrode gaps, leading to unreliable spark and repeat no-heat callbacks.
• Install Difficulty: 2/5 — Shut off gas supply and 24V power before servicing. Tools needed: ¼" hex driver, needle-nose pliers. Disconnect the high-voltage ignitor cable, remove the mounting screws, swap the electrode assembly, and reconnect. Always inspect the ignitor cable (50HJ403024) for cracks while the burner box is open.
