OEM Carrier Hot Surface Igniter 48VL400002 for Model PY4GNAB36090NA

This is the factory-specified OEM hot surface igniter (spark electrode ignitor) for the Carrier PY4GNAB36090NA packaged gas/electric unit. The hot surface igniter is the component responsible for igniting the gas burner on every call for heat. When it fails, the control board will attempt ignition, detect no flame, and lock the system out — leaving you with a blinking error code and no heat. Replacing this igniter with the correct OEM part restores safe, reliable ignition performance matched to the factory control board's timing sequence.
