If it were mine I'd clean the rust out and check it. Give it a gentle
thump to make sure theres still good solid metal there. If a hole
appears, its bin time. Small holes dont let microwaves out, the door
is full of holes, but of course you want to bin it before it becomes
undsfe not after, so once it holes, I'd ditch it.
Rust in microwaves is common, and they work fine for many years after
rust appears. Could well still have a decade in it.
That's just what I do anyway.
We had a similar problem with a Sharp microwave after quite a short
timeframe - so did my sister (we bought them both at the same time) - it
just didn`t vent steam efficiently (at all ?)
We bought a replacement Panasonic, and my missus almost wet herself
laughing when I tried to set the time and it refused, the display
scrolling "please read the manual" ;-)
We`ve been most impressed with it overall and have been happy to
recommend them to others.

Reminded me of the reply when we asked our service manager how to test for
microwave leakage "lick your forefinger, run it slowly around the seal with
the microwave operating on full power, observe your finger. If it has
changed from pink to black and smoking then there's a leak". Oh for the
pre-nanny state days when advice like this was the norm and expected to be
I guess microwave technology is not really a DIY subject.
myth. They were fine by 1983. If it were 1970s that would be
myth. They just changed the rating system.
Myth. Microwaves haven't used door seals for over 20 years.
me neither. It doesn't make any sense to me to buy something, then
throw it away for no senible reason and give away your money again,
over and over. People who do that are true suckers.
I dont agree, a PAT tester who does that is being careless. If theres
rust you need to check its sound and solid, thats all.
Ask an electronics newsgroup about electronics, and a DIY group about
What's the metal bit in the door with the castellated edge for then?
Or do you mean the rubber bit..and why do the destructions always tell
you to keep the rubber bit clean to "prevent microwave leakage"?
Just askin :-)
I didn't realise the wavelength was that long, not that I'd bothered to
work it out though :)
I've just done some Googling, and it turns out that this design is a
"quater wave slot" or "choke" type of door seal.
Oh well, at least I learned something anyway :)
OK, badly phrased. "What is the seal of the door like?" A bent/dented
door or cavity opening face will leak or one with lots of general
microwave detritus stuck on it preventing the door from closing fully
(but still latching to overcome the interlock(s)).

Hmm...battery, led and sensitive FET should show up any leakage ;)
( I have a "volt stick" thingy that is really sensitive to MW leakage)
Or possibly of those silly "flashing" things that flash when you receive
a mobile call? :-)
