OEM Carrier Spark Electrode Igniter 48GS400168 for Model PY3PEA036090AB

This OEM spark electrode igniter assembly is the factory-specified replacement for the Carrier PY3PEA036090AB packaged gas/electric unit. The igniter generates the high-voltage spark at the burner that ignites the gas-air mixture on each heating call. When this component fails, the control board detects a failed ignition trial and locks out the system — leaving you with a furnace that attempts to start, produces a clicking sound, but delivers no heat. In some cases the unit will attempt multiple ignition retries before going into hard lockout, requiring a manual reset.

• Part Number: 48GS400168 | OEM Spark Electrode Igniter Assembly | Factory Authorized Carrier Replacement Components Division
• OEM vs Generic: This is a genuine OEM assembly with factory-matched electrode gap, ceramic insulator rating, and lead wire length. Generic igniters frequently ship with incorrect electrode spacing or inferior ceramic insulation, leading to misfires, cracked insulators, and repeat failures within one season.
• Install Difficulty: 2/5 — Disconnect power and shut off gas before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter (to verify spark circuit continuity post-install). Photograph all wire connections and routing before removal. Ceramic insulators are fragile — handle by the bracket only.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our stocked warehouse — order before 3 PM local time.

Compatibility: Engineered for Carrier PY3PEA036090AB packaged units. Verify your existing igniter type and lead wire configuration against your unit's data plate before ordering — some model variants may use a hot surface igniter instead of a spark electrode assembly. Our fitment team is available to confirm compatibility before you order, ensuring the right part arrives the first time.
