The oven has been in the same place since it was first installed.
Yesterday I turned the top oven on and a few seconds later the
main RCD for the whole house tripped.
I reset the RCD and it hasn’t tripped since.
However, the top oven will not heat beyond 150 deg no matter how long I leave it.
The oven indicator light stays on and will only go out when I turn the heat back down to 150 deg.
The grill and main fan oven work fine.
I’m thinking it’s the heating coil but could it somehow be the control knob?
