How does a flame sensor works?
A flame sensor is a safety mechanism installed on gas furnaces. It is located directly between the burners and the gas supply. When your gas kicks on, the flame sensor MUST detect a flame. This safety mechanism is to prevent your house from filling up with un-lit gas. Even if your burners are igniting, if your Flame Sensor is dirty (covered in carbon from typical use) it will fault out, thus shutting off the furnace over and over. If this is the case, your furnace will kick on every 2 minutes (because the thermostat tells it your house is too cold) and then will shut off after 5 or 10 seconds as a result of the Flame Sensor Fault.
What does a Flame sensor in a hot surface ignition furnace do?
It tells the furnace that it lit... Hence the name Flame Sensor.
What is the purpose of a flame sensor?
A flame sensor is a program used to detect "flame" on various blogs or comment boxes. Various Websites may use these sensors to dish out trolls or other internet vermin. On the other hand a flame sensor is also a device used in machines that are subject to very high temperatures. For example, a flame sensor is standard in many home ovens. So this in fact is a very useful safty feature.l
How do you clean a FLAME SENSOR?

How does a flame sensor work in home furnaces by using a metal rod in the flame?
Its not a flamesensor its a pilot generater it generates a small amound of electricity to open the main valve that way if your pilot light goes out it wont let gas escape and couse a potentian explosion The above answer is not accurate unless you have a standing pilot model furnace. Then the "flame sensor is called a thermocouple, much different than the flame sensors used in Direct Spark Ignition, hot-surface and intermitant ignition furnaces. The flame sensor uses the flame of the main burner to prove flame at the circuit board by measuring conductivity to ground through the flame.
On a gas furnace what energizes the blower motor in heat mode?

How does flame rectification works in a gas furnace?
AC voltage(at least 90vac) pass through the flame sensor and the ionization of the flame creates or rectifies the voltage to DC and a small microamp that can be measured with a meterl.
