No. Stop using it and unplug it. Sparking can be caused by a damaged waveguide cover, metal objects or damaged interior coating, and continued use can cause more damage.
A fuse that keeps blowing is usually a sign of a failed door switch (interlock) or a high-voltage component problem. The underlying cause needs to be repaired.
