My Samsung BT621VDST has recently started tripping the rcb.

This answer was rated:

My Samsung BT621VDST has recently started tripping the rcb. Works fine for a while- even over an hour but then cuts out and won't restart without immediately tripping the power until it's cool. Wondered if it was linked to moisture in the cooking. Engineer checked everything with his meter and couldn't find any faults. Any suggestions what it could be?
Hello, my name is George..
This problem is usually caused by a breakdown in the installation in one or more of the elements. If this is the case, and it most likely is, it is called an accumulation. The element does not show any fault whilst cool, but then as it/they heat, the hotter it/they get, the more the installation can break down causing an earth fault, thereafter tripping the consumer unit.
Kindly be patient whilst awaiting any responses from me as I'm not constantly available.

Is it more likely to be a fan element or a heat element do you think? Is there one that this model of oven is more prone to. Also is it something I could fix myself or would it be for a repair guy
Good morning.. Which oven are you using at the time that the appliance trips the circuit?
Customer: replied 2 years ago.
So far it has happened when using just the top oven and also when using the large oven ( top and bottom together without the divider shelf) .
Ok thank you for that information...
Can you put the oven into SINGLE MODE, LARGE GRILL ONLY and let me know if the oven trips then..
Customer: replied 2 years ago.
Hello again. I did as you asked. The grill was on for an hour and didn't trip the power. What next?
Then the upper of the two fan oven elements needs changing.

Thanks George. Do you mean the top fan or the top heater?
Not the fan, or the top heater, but the element that surrounds the top fan
