A dirty or faulty flame sensor will often cause the furnace to start and stop frequently or not start at all. If your flame sensor is dirty it can be removed and cleaned with steel wool or fine sandpaper. If this does not work it will need to be replaced. Though a homeowner can clean a flame sensor, it can be quite brittle. Also, there may be more to the problem than just the flame sensor. For this reason, it's often a good idea to have a licensed heating contractor do this sort of repair.
If you would like to have a contractor look at your furnace's flame sensor, we can help you find one, here.
