Bad overheat limit switch keeps locking the furnace out or the regulator is bad causing it to run to hot
Bad overheat switch will not close/reset just by pulling the fuse and reinstalling the fuse. Possible problem is just a bad ignition module. Bad modules will run and shut down but not restart the 2nd cycle. BUT, you SHOULD be able to turn the furnace OFF at the wall tstat and restart the wall tstat and the furnace will engage that first cycle then stop. Pulling the fuse will do the same thing as turning the tstat ON and OFF. Doug
