The microwave was not made in the U.S.A.
I had a top brand over the range microwave built for a U.S company in the Philippines, a loud buzz occurred, and it burned.
I have the same brand currently, built in Maylasia, the loud buzz is back. The combined age of these microwave units is under three years.
I bought a counter top USA built microwave in 1980. It still works very well.
