OEM Carrier Spark Electrode Ignitor 48GS400168 for Model PY2PNB036090AA

This is the genuine OEM spark electrode ignitor assembly for the Carrier PY2PNB036090AA gas packaged unit. The spark electrode ignitor is a critical component in your unit's ignition sequence — it generates the electrical spark that ignites the gas burners on each call for heat. When this part fails, the system will attempt ignition, fail to light the burners, and enter a safety lockout, leaving you with no heat. Common symptoms include repeated clicking with no ignition, error codes indicating ignition failure, or the unit cycling off after one or two unsuccessful ignition attempts.

• Specs: Spark electrode / 2-rod ignitor assembly | OEM Part# 48GS400168 | Factory-matched fit and spark gap for Carrier PY2PNB036090AA gas pack units | Replaces: 48GS400168
• OEM vs Generic: This is a genuine Carrier Factory Authorized Part — not an aftermarket approximation. OEM igniters maintain the correct electrode gap, ceramic insulation rating, and wire harness length. Aftermarket substitutes frequently have inconsistent gap tolerances that lead to hard starts or premature failure.
• Install difficulty: 2/5 — Always shut off gas supply and power to the unit before beginning. Tools needed: flathead and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers. Photograph existing electrode orientation and wiring connections before removal. Handle ceramic insulator with care — do not touch electrode tip with bare hands.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our NationalHVACParts.com warehouse.
