OEM Carrier Hot Surface Igniter (48VL400002) for Model PY3GPAA48115AA

This is the OEM factory-specified hot surface igniter (spark electrode ignitor) for the Carrier PY3GPAA48115AA packaged gas unit. The igniter is the first critical link in the heating sequence — it heats to ignition temperature within seconds of a heat call, lighting the burners reliably every cycle. When it fails, the furnace or packaged unit will attempt ignition, fail to light the burners, and enter a lockout condition — leaving you with no heat and a flashing fault code on the control board.

• Specs: OEM Part No. 48VL400002 | Spark electrode ignitor | Factory-matched mounting geometry and element rating | Compatible with natural gas and propane configurations on the PY3GPAA48115AA
• OEM vs Generic: This is a genuine OEM Carrier igniter — manufactured to exact factory tolerances for element temperature, warm-up timing, and mounting fit. Generic igniters vary in resistance and geometry, which can result in nuisance lockouts, premature cracking, or incompatibility with the unit's control board ignition timing sequence.
• Install Difficulty: 2/5 — Shut off power and gas supply before beginning. Tools needed: 1/4" and 5/16" nut drivers, flat-head screwdriver. Handle the igniter element with care — skin oils from bare hands can cause premature failure. Photograph all wiring connections before disconnecting. Allow the unit to cool fully before servicing.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In-stock and ships same business day from our warehouse.
