What causes sparking inside microwave?
Sparking inside
microwave is a common problem. It requires you to immediately switch off the
microwave and perform necessary inspection before calling a professional for
microwave repair.
Possible reasons behind microwave sparking problem
are:
Metal scarp inside microwave: A small metal piece is enough to cause a spark inside 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 the heating dish is not microwave
safe, there are fair chances of sparking inside microwave. So make sure that
there is no metal scrap and your heating dish is microwave safe before you
start cooking food in microwave. In case of microwave sparking problem inspect
the microwave for metal scrapes before calling a professional for microwave
repair.
Damaged wave guide cover: A
very common reason of sparking inside microwave is a damaged wave guide cover.
Waveguide covers the magnetron which guides the heat waves to the central area
where food is kept. This prevents any food particle or bug from entering the magnetron.
It is very common that during cooking, some food particles escape the food and
stick to the wave guide. The heat emitted from the magnetron burns these stuck
food particles, which appears as spark. The spark damages the wave guide cover
of microwave. The solution is to replace the burned wave guide cover with a new
one. In case of microwave sparking problem inspect the waveguide cover before
calling a microwave repair professional.
Damaged Rack support: Microwave
sparking can also be due to faulty rack support. A rack support is a hook like
part inside microwave. If the microwave is sparking near one of the support
rack, this means that the paint on the rack has worn out.
Diode burn: The high
voltage diodes could be shorted or burned causing sparking inside microwave.
If you see spark
inside microwave immediately switch off the microwave and perform the necessary
inspection before calling a microwave repair professional.
