The problem is most likely caused by a defective magnetron that "heats the food" is loading down the high voltage transformer causing it to make a loud buzzing sound. The cost to repair (depending on make and model) will probably approach the cost of a new microwave oven when you factor parts and labor.

The microwaves are produced by what is known as a KLYSTRON TUBE. Like anything, early failure is possible. There is also the possibility that the transformer or electronic circuit providing the correct voltage to the KLYSTRON has failed, either from over-use, manufacturing defect, or leakage from the KLYSTRON enclosure, which creates heat.
With microwaves being as CHEAP as they are, replacement should not be an issue.

Longer heating times may indicate a magnetron tube that is old.

Microwave ovens beam their energy in the form of an inverted cone thus most of the energy falls in a circle outside of the center.

Move your article to be heated to the outside of the oven and use more of whats left of the dwindling heating source.
