OEM Carrier Hot Surface Spark Electrode Igniter for Model PY2PPB036090AA

This OEM hot surface spark electrode igniter (part number 48GS400168) is the factory-specified replacement for the Carrier PY2PPB036090AA packaged heating and cooling unit. The igniter is the first critical component in the ignition sequence — the control board energizes it to reach ignition temperature, allowing the gas valve to open and the burner to light. When the igniter fails, the system will attempt a light cycle, fail to sense flame, and enter a safety lockout — leaving you with a system that blows cold air or no air at all.

• Specs: Spark electrode igniter | OEM part number 48GS400168 | Factory-matched geometry and element rating | Compatible with Carrier PY2PPB036090AA packaged unit platform
• OEM vs Generic: This is a genuine OEM Carrier igniter — manufactured to exact element composition, tip geometry, and temperature curve specifications. Aftermarket igniters often use inferior silicon carbide that cracks prematurely under thermal cycling, leading to repeat failures within one season.
• Install difficulty: 3/5 — Turn off gas supply and 24V control power before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter to verify element continuity (typical reading 40–75 ohms). Handle the igniter element only by its mounting bracket — skin oils cause hot spots and premature cracking.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
