How does a flame sensor? A furnace flame sensor works by detecting the presence of a flame within the furnace. … As the gas valve opens to begin the combustion process, the current is sent out from the sensor in order to detect the presence of heat from a flame.
What happens when flame sensor goes bad? What happens when a flame sensor goes bad? … If your flame sensor is dirty or faulty, it will automatically shut down the heating unit if it doesn’t detect a flame. Most furnaces will go into a safety ignition lockout when a shutdown happens three times.
How do you test a flame sensor? You can measure flame signal by putting your meter (capable of measuring micro amps) in line between the flame sensor and the wire that was connected to it (see picture). If you are reading anything under 5 uA (micro amps), it is likely that your flame sensor is dirty.
How does a flame sensor fail? Good flame sensor: A properly functioning flame sensor will shut down the gas valve when it does not sense a flame when the furnace should be firing. Bad flame sensor: When the furnace has fired and is burning hot, a bad flame sensor won’t sense the heat and will shut down the furnace.
