Is the radiation likely to be leaking out into the rest of the kitchen?

No, probably not. If you aren't sure, go buy a microwave radiation tester
and follow the directions included with it to find out. Keep in mind that
while they aren't the most accurate thing around, they will detect serious
problems.

those are pointless. A visual inspection to ensure no rust holes and
the door closes is the only leakage test relevant to modern ovens. For
30+ year old ovens things are different, and the best advice is to dump
them.


As some have mentioned, the magnetron tube may be wearing out. However, I
think you'll find the trouble may be elsewhere. Just about all microwaves
have an electric fan inside that cools the magnetron to keep it from
overheating.

If this fan is sticky, gummy or can't get up to full speed, this may be the
only problem. Even if the fan sounds fine, it's worth taking a look at the
vents on the unit to be sure they are not plugged.

that wouldnt affect cooking power delivery afaik.


If the oven checks out, look at your household wiring. Perhaps the circuit
you've got the oven plugged into cannot deliver the power needed to make the
microwave work efficiently.

smoke or flames coming outta the wall socket would indicate that
problem. Otherwise the oven will be getting the power it wants.
