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.

Thanks to everyone for their useful responses, from which I can assume
that a service isn't required, and that it would be ok to unscrew the
casing (having unplugged first) and replace the bulb (having ensured
the correct size) myself - as long as I don't touch or fiddle with the
circuitry. If I can clean the fan filter so much the better.
Please let me know if I've misread the situation, but other than that
thank you all again. What a useful group!
