[ELECTRON] advice on electrical issue, trivial OTO

[Clive Mitchell]

This sounds like the earth leakage breaker (RCD) is tripping due to
leakage from a failing heating element.  Cookers are notorious for
causing earth leakage issues due to the inevitable spillage of liquids
and sticky foodstuffs into their internals, but there's a good chance
that if you turn the power to the oven off and feel around its element
you may find it is deeply pitted in one or more parts.  If it is, then
you should be able to source a new heating element quite easily.

Earth leakage tripping can be a real nuisance at times.  There's a
tendency for the leakage detection breakers in older distribution
boards to "fail safe" and gradually get more sensitive to tripping.
This is why modern testing includes a test at half their rated current
to see if they are over-sensitive.
