I needed one tool to remove the screws from the back of the dryer and a screwdriver for the fuse.  Here's the steps I used: Unplug the dryer.  Remove the vent hose from the back of the dryer.  Remove the screws from the back of the dryer.  Unplug the two wires on the fuse.  Remove the screw from the fuse and pull the fuse out.  Put the new fuse in place and snug the screw down.  Plug the two wired onto the new fuse.  Put the back on the dryer.  Hook the vent hose back up.  Plug the dryer in.  My dryer runs hotter now than it has in a long time.  HINT:  While you have the dryer pulled out, ensure the vent hose is clear, as a clogged vent can is one of the things that can blow the fuse to begin with.
