Probably call an electrician.
When I worked as an appliance repairman I got a few calls for an oven or a dryer blowing fuses. I always went to the fuse box first and tightened all the screws. I never shut off the main. What would the homeowner think?
Boxes with old screw-in fuses were the worst at having a bad connection between the fuse and the buss. It would cycle hot over and over and somehow the screw would get loose. I would tighten the screw with a long handled screwdriver and screw in a new fuse good and tight and voila! the dryer was fixed.
Once I somehow hit the side of the box with the screwdriver and caused some sparks and melted steel. Another time I managed to weld a screwdriver to the side of the box hard enough to blow the main. I still don't know how I did it. So, yes Probably call an electrician.
