Carrier 48VL400001 Flame Sensor

The Carrier 48VL400001 is a safety device used in gas-fired carrier HVAC equipment including furnaces and boilers. In operation it is used as a flame sensor to constantly monitor and ensure that there is a flame within the burner assembly. This sensor produces a tiny amount of electrical current when it comes into contact with the heat of the flame. This current signal is received by the control board of the HVAC system. In case the control board does not sense the required current, it turns off the supply of the gas. This crucial safety measure helps avoid gas leaks, and possible risks, to assures that your Carrier HVAC equipment functions as intended.
