OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY3PNA060090AA — Part # 48GS400168

This OEM hot surface igniter (spark electrode ignitor) is the factory-specified replacement for the Carrier PY3PNA060090AA gas furnace. The igniter is the first critical component in the furnace heating sequence — it heats to over 2,000°F to light the gas burners reliably and safely each cycle. When the igniter fails or cracks, the furnace control board will attempt ignition, detect no flame via the flame sensor, and enter a hard lockout — leaving you with no heat. Replacing the igniter with the correct OEM part restores factory ignition timing and longevity.

• Specs: OEM Part # 48GS400168 | Type: Spark Electrode / Hot Surface Igniter | Factory-matched mounting bracket and lead wire length | Rated for Carrier PY3PNA060090AA gas furnace application
• OEM vs Generic: OEM igniters are manufactured to exact factory resistance tolerances and silicon composition. Generic igniters often exhibit shorter service life, premature cracking from thermal cycling, and inconsistent ignition timing that can cause nuisance lockouts.
• Install Difficulty: 3/5 — Gas furnace work requires care. Tools needed: Phillips and flat-head screwdrivers, 1/4" nut driver, needle-nose pliers. Always shut off gas and 120V power before servicing. Never touch the igniter element with bare hands — skin oils cause hot spots and premature failure. Photograph all wiring connections before removing the old igniter.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM ship the same business day from our stocked warehouse.
