OEM Carrier Flame Sensor (48GS400192) for Model PY3PNA036060AB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PNA036060AB gas furnace. The flame sensor is a critical safety component: after the igniter lights the burner, the sensor's rod detects the presence of flame via electrical rectification or ionization and sends a confirmation signal to the control board. If the board doesn't receive that signal within a few seconds, it cuts gas flow and locks out the furnace — a critical safeguard against unburned gas accumulation. A failed or carbon-coated sensor is one of the most common causes of a furnace that lights briefly and then shuts off after just 5–8 seconds.
