What a Flame Sensor Is and Why It Matters
Receiving your routine furnace maintenance helps keep your heating system operating up to 30% more efficient and helps extend the life of your system. But things can still stop working, and when they do, you may feel like it’s always something else.
This time it’s your heat exchanger, next time it’s your pressure switch. Now you need to replace your flame sensor.
Also, what is a flame sensor?
A flame sensor is an important safety element on your gas heating system. During the ignition sequence, your gas furnace goes through a process where a spark or a hot surface ignitor will ignite the gas. Once the gas is ignited, the flame sensor produces a current of electricity. The current is quantified in micro amps. If the furnace’s control board does not read the right level of micro amps, the furnace will stop giving the system fuel to stop an explosion.
Over time, if the flame sensor is not cleaned appropriately, oxidation or carbon buildup can hinder the flame sensor’s ability to work properly, which can end up causing the heating system to malfunction.
The way to establish if a soiled flame sensor is causing a furnace malfunction is to take a micro amp draw reading, which an expert heating technician can give you. If a dirty flame sensor is the guilty party, the heating expert will clean the sensor with steel wool. If dirt was the only factor, we will see a significantly higher amp reading. If the reading does not change, the technician will proceed with the heating system repair diagnostic process.
