Interesting.  How did you measure the output?

At my previous job, we had a microwave that cooked food more and
more unevenly, leaving some of it frozen at times.  I noticed
that the door latch was a little loose.  I took the thing to
the bench, took it apart, tightened the latch screws, and it
worked fine.  Check if this may be your problem.

Incidenty I never stand in front of a microwave when it is
cooking.  Now you know why.
