Is the codes not posted on inside of door/cover? If not I doubt anyone can help you without a model number off the furnace

The code means loss of flame more than 5 times in a single cycle. Probably the flame sensor is dirty or needs replaced. You can try pulling it out and cleaning it off with some fine steel wool or a scotch brite pad and put it back, if that doesn't work I'd replace it.
