Welcome to the forums.
If it's a basic high limit fault..... it will clear by allowing the furnace to cool, turn power off and then back on.
If the fault is still there it my be a flame rollout switch mounted directly above the burner. The rollout switches will have a little red reset button on them. If that's the problem the furnace needs to be professionally serviced as that is a major problem.
If you look thru the blower door sight glass you should be able to determine which actual fault you are getting.
