OEM Carrier Flame Sensor (48GS400192) for Model PY3PNA030060NB

This OEM 90-degree flame sensor with mounting bracket is the factory-specified replacement for the Carrier PY3PNA030060NB gas furnace. The flame sensor uses ionization/rectification technology to detect the presence of a burner flame after ignition. When the burner lights, the flame produces a small electrical signal through the rod; if the control board does not receive that signal within 5–8 seconds, it cuts gas flow and locks out the furnace as a safety measure. A failed or carbon-coated sensor is one of the most common causes of a furnace that lights briefly and then shuts off repeatedly.
