Re: Electric fan oven just tripped the RCBO.

My sister moved house about 3 years ago and took her cooker to the new property, and it worked perfectly until she used the oven and it tripped the breaker. This happened every time she turned the oven on.

My brother was an electrician, so he went round to see what the problem was. After tracing through the circuitry he discovered that the oven had a light that came on to show that it was heating and went off when the oven was up to temperature. The feed side was wired to the "normally closed" connection on the thermostat, and the other side was wired to the chassis, so effectively to Earth. The new house had a more sensitive ELCB then the previous house and the tiny current through the indicator light to Earth was enough to trip the breaker. He rewired the earthing wire to Neutral instead and all the problems went away.

Your oven at 13 years old might have a similar wiring problem.

I have tested with the oven isolation switch off, and the RCBO doesn't trip.

Thanks for that. I'm not up to any heavy lifting for a while (surgery) so removing and replacing the oven is a bit too risky at the moment.

However there is a local appliance repair firm. They don't list any compatible but cheap elements so I will forward this link to them and see what they think.

Today they are not listing anything but the Samsung part.

Less than a month ago there were more options.

Gah!

How about any of these?
