OEM Carrier Hot Surface Spark Electrode Igniter for Model PY1PPB048090AAAA

This is the genuine OEM factory-specified spark electrode igniter (part number 48GS400168) for the Carrier PY1PPB048090AAAA packaged gas/electric unit. The hot surface igniter is a critical component in the furnace ignition sequence — the control board energizes the igniter, which heats to temperatures exceeding 1,800°F to light the burner. When this part fails, the system will attempt ignition, fail to establish flame, and enter a safety lockout, leaving you with no heat. Common failure symptoms include error codes indicating ignition failure, the furnace cycling on and off repeatedly, or a complete no-heat condition after the inducer starts.

• Specs: Spark electrode igniter | OEM part number 48GS400168 | Factory-matched geometry and ceramic insulator | Designed for Carrier packaged gas/electric systems
• OEM vs Generic: This is the genuine OEM Carrier igniter — factory-matched mounting dimensions, electrode gap, and ceramic composition. Generic igniters can have inconsistent electrode gaps and lower-grade ceramics, leading to premature cracking and repeat failures, especially under thermal cycling stress.
• Install difficulty: 3/5 — Turn off gas supply and 24V control power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, work gloves. Critical: Never touch the ceramic igniter body with bare hands — skin oils cause hot spots that crack the element. Handle only by the lead wires or mounting bracket.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day when ordered before 3 PM local time.
