Re: [OT] Microwave Woes

["Tim Fletcher" <timfletcher@xxxxxxxxxxx>]

My 2YO sharp microwave has taking to producing impressive flames etc
inside.
On closer inspection the exit of the Microwave "tunnel" is
covered with a
postcard-sized silver micaceous material which has become thinned and is
starting to burn through.  I must be able to get a spare as it just slots
in, but I don't know what it is called and if the device is safe to use
without it?

Any steers?

Tim.
