When does a microwave oven require a service - and what can be
serviced anyway?

Never.

Not much.

These things are VERY dangerous and you should only try a repair if you have
enough brains to avoid being killed by them.

To quote an earlier message

WARNING: Microwave ovens are the most dangerous consumer appliance to
service due to the up to 5,000 V at high current inside. Even with the
power off, there is a HV capacitor that can produce quite a kick. This
capacitor must be discharged before touching anything in the microwave
generator circuitry.


Don't even think about tackling it yourself unless you have the appropriate
background and have thoroughly studied the Microwave Repair FAQ at the site
below as well as the info at: http://www.gallawa.com/microtech/, or a book
on
microwave oven repair. There is one by Homer L. Davidson that may be
available at your public library.


Especially the SAFETY warnings and guidelines.
