OEM Carrier Spark Electrode Ignitor Assembly 48GS400168 for Model PY2PNB024060AA

This is the genuine OEM spark electrode ignitor assembly (part number 48GS400168), the factory-specified replacement for the Carrier PY2PNB024060AA packaged gas unit. The spark electrode ignitor is a critical ignition component — it generates the high-voltage spark that lights the burner assembly at the start of every heating cycle. When the electrode fails, cracks, or becomes fouled with carbon deposits, the control board cannot confirm ignition, causing the unit to lock out on a fault code and deliver no heat.

• Part Specs: Spark electrode ignitor assembly | Dual-rod design | Factory-matched electrode gap and ceramic insulator | Mates directly to OEM high-voltage ignitor cable and bracket
• OEM vs Generic: This genuine Carrier Factory Authorized Part is manufactured to exact OEM electrode geometry and ceramic insulation ratings. Aftermarket alternatives may present incorrect spark gap or inferior ceramic bodies that crack under thermal cycling, leading to repeat failures.
• Install Difficulty: 2/5 — Shut off gas supply and disconnect power before beginning. Tools needed: 1/4" and 5/16" nut driver, needle-nose pliers. Photograph the existing electrode orientation and wire routing before removal. Reconnect high-voltage ignitor cable securely and verify electrode gap matches original placement before restoring power.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
