OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY1PEB048115NBAA — Part #48GS400168

This is the OEM factory-specified spark electrode igniter (part #48GS400168) for the Carrier PY1PEB048115NBAA packaged heating and cooling unit. The hot surface igniter is a critical component in the furnace ignition sequence — it heats to extreme temperatures to ignite the gas burner on each heating call. When the igniter fails or degrades, the control board will attempt ignition, detect no flame, and lock out the system, leaving you with zero heat. Common symptoms include a furnace that starts the inducer motor but never produces heat, repeated ignition lockout fault codes, or a visibly cracked/broken igniter element.

• Specs: OEM Spark Electrode Igniter | Part #48GS400168 | Factory-matched geometry and electrical resistance | Designed for Carrier PY1PEB048115NBAA packaged unit
• OEM vs Generic: This OEM igniter is manufactured to exact Carrier factory specifications for resistance, element geometry, and bracket mounting. Generic igniters often deviate in resistance values or tip angle, causing misfire, nuisance lockouts, and premature failure — especially in packaged rooftop applications with high vibration environments.
• Install Difficulty: 3/5 — Access requires removing the burner compartment panel on the packaged unit. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter (to verify resistance ~40–90 Ω before install). Do not touch the ceramic element with bare hands — skin oils cause hot spots and premature cracking. Always disconnect power and confirm gas is off before servicing.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before cutoff ship same business day from our warehouse.
