Tip & How-To about Heating & Cooling
In my experience I have seen many people use sand paper to clean the flame sensors on furnaces. It is best to use a small stainless steel brush to remove any chemicals that have been burned on the sensor. If you are cleaning the sensor you will want to remove it from the appliance and then hold it firmly while brushing off debri. Be sure to not loosen the sensing rod from the ceramic collar or it may move and cause a whole nother set of problems. The reason why I use a brush, a brush doesn't leave a silica residue on sensor that will become glass when heated further impeding the sensors job of sensing current through the burning gas.
Hope this helps

The flame sensor is located in the burner box of this unit. You may have to remove a cover plate to get to it. It will either look like a small probe or small diameter copper pipe (real small).
It will either be close to the pilot or ignitor or aways away where the flame has to travel to it.
A small brush or sand paper can be used to clean it.
If your furnace has more than one burner, while you are inside, clean out the track that allows the flame to travel to each burner. A small can of compressed air works great along with a small wire bruch.
