OEM Carrier Hot Surface Igniter (Spark Electrode) for Model PY3GNA048115AA — Part 48VL400002

This is the factory OEM spark electrode igniter for the Carrier PY3GNA048115AA packaged gas/electric unit. The hot surface igniter is the first component in the ignition sequence — the control board energizes it to reach ignition temperature, then proves flame before opening the gas valve. When the igniter fails or cracks, the furnace or packaged unit will attempt ignition, fail to light, and enter a hard lockout — leaving you with no heat. Part number 48VL400002 is the direct OEM replacement, ensuring your system restores normal ignition on the first attempt.

• Specs: OEM spark electrode / hot surface igniter | Factory-matched geometry and element rating | Replaces part number 48VL400002 | Designed for Carrier PY3GNA048115AA packaged units
• OEM vs Generic: This OEM igniter is manufactured to exact Carrier factory specifications for element resistance, mounting geometry, and temperature ramp rate. Generic igniters may have mismatched resistance values or off-center electrode positioning, leading to nuisance lockouts or premature failure.
• Install Difficulty: 3/5 — Always shut off gas and 120V power before servicing. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Handle the igniter element only by its mounting bracket — skin oils on the ceramic element will cause premature cracking under heat. Never apply power to the igniter outside of the assembly.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
