1. Metal scarp inside microwave
A small metal piece is enough to cause a spark inside your microwave. For example you may have cleaned the microwave with steel wool and left behind some metal scrap from the wool. Also sometime the food which you heat has a foil covering over it that catches fire. If your heating dish is not microwave safe, there are fair chances of sparking. So make sure that there is no metal scrap and your heating dish is microwave safe before you start cooking food in your microwave.
2. Damaged wave guide cover
There is a cover called wave guide cover over the magnetron which conveys or guides the heat waves to the central area where food is kept. Wave guide cover also prevents any food particle or bug from entering the magnetron.

It is very common that during cooking, some food particles and grease escape the food and stick to the wave guide. The heat emitted from the magnetron burns these stuck food particles, which appears as spark to us. This spark damages the wave guide cover. A damaged or shorted wave guide cover causes frequent sparks. So the solution is to remove the burned wave guide cover with a new one.
