Our micro-wave oven just turned-off this week. We tried to plug it eleswhere in the house and we checked the breaker in the electric panel. The problem comes from the mirco-wave. We have been informed that some mirco-waves have fuse inside and it might be burned. Do yiu know if this model includes a fuse and if yes, where it is located? I tried to removed some screws but some of them required a special screw driver as there is a point in the middle of the screw. Impossible to remove.
