My furnace will not come on and the fuse keeps burning out what could be the problem.
We do not want to all a repairman if we can fix it ourselves.

If the fuse keeps going bad it means you have a short circuit. If you are capable and have a meter and know how to use it you can trace the wiring down and find the short. If you are not capable of this you need to call for professional help to come to your home and find it for you.
