My Neff double oven is tripping the MCB on the mains.
This occurs when I switch on any function of the top oven. The model is U1744N (around 15 years old). The top oven has a double element at the top (grill and oven) with a second element under the casing at the bottom of the top oven. The bottom oven is fan and has multiple elements, but this is all working correctly and can be used without problem.
I have taken out the oven and removed the rear casing (after disconnection). The element connection points and all aspects of the wiring look undamaged with no signs of arcing. I have removed the top element and visually, it looks ok - there appears to be no physical damage. Testing the two separate circuits of this element with a multimeter shows resistance of over 40 . I tested the second element of the top oven without removing it by taking off the clips and testing resistance, this also showed over 40.
However, I'm still having the issue of the MCB tripping. It first happened a few weeks ago and having left it for a few days, I tested it again and it worked without issue. It is now happening all of the time. It's not the end of the world as we still have the bottom oven, but I'd like to try and repair it.
Can anyone please suggest other steps to try, or should I assume one or both of the elements are faulty and swap them out?
