There is a sensor that tell the furnace controls the pilot is on. It is likely dirty, mispositioned, or bad. It will be some sort of a doo dad with 2 wires near the pilot light. Some older furnaces may have a thermocouple which looks like a 1/8'' copper tube with a fatter cylinder on the end. Identify and replace the thing, and your furnace should work. Any hardware store will have the thermocouple, but a modern sensor may have to come from a dealer.

This may be a problem you can fix cheaply and easily. I get tired of questions where all I can do is suggest trying an expensive circuit board.

Bryant often used an auto pilot assembly, (Often called a pilot burner assembly) it can have 2 or 3 wires to it. (It sounds like yours has 3 and the n/c normally closed position is not making contact in the n/o normally open position) If this is the case, it is probably bad , I replace dozens of these every year. Having the age of the furnace would be a big help.
