Setting up your annual furnace maintenance helps keep your heating system operating up to 30% more efficient and helps extend the life of your system. But things could still go wrong, and when they do, you might feel like you’re always hearing about something else.
This time it’s your blower, next time it’s your control board. Now you need to replace your flame sensor.
A flame sensor is an important safety component on your gas furnace. During the ignition cycle, your gas furnace goes through a process where either a hot surface ignitor or a spark actually ignites the gas. When the gas is ignited, the flame sensor generates a current of electricity. This is measured in micro amps. If the furnace’s control board doesn’t read the correct level of micro amps, the furnace will stop giving the system fuel to avoid an explosion.
Over time, if the flame sensor is not cleaned appropriately, oxidation or carbon buildup can interfere with the flame sensor’s ability to operate properly, which can cause the furnace to malfunction.
The way to establish if a dirty flame sensor is to blame for a furnace malfunction is to take a micro amp draw reading, which a professional furnace technician can provide you. If a dirty flame sensor is the culprit, the technician will clean the sensor with steel wool. If dirt was the only factor, we will see a notably higher amp reading. If the reading does not change, the technician will proceed with the furnace repair diagnostic process.
