There is a short somewhere that is causing excessive current draw. Very
commonly, this can be the HV rectifier, magnetron, main capacitor, or the
main power transformer. There is also the main uPC board to be concerned
about as well.
These are difficult to service, unless properly trained, and have the proper
tools to work on them. Also, there are some very serious safety issues with
working on microwave ovens. Many of the replacement parts in these have to
be factory original. You would also need parts on hand for testing.
I would suggest that you either give it to their authorized service centre
to have an estimate, or to buy a new one.
