I am in the process of repairing my Zanussi ZCV667mx lower oven, it has
two ovens. Basically the thermostat has failed meaning the over heat
thermostat has also gone. I noticed when looking at the spare parts
available that there is also what is described as a 230 centigrade
thermostat N0 and also described as TEMP OVERHEAT 230 N C KLIXON. What
is this for. Is it for the Grill protection. I ask this as the grill
works but when on after a while the house RCB trips and as yet not sure
what would cause this.

I'd imagine the RCD trip is a faulty grill element, leaking to earth when
hot.

They are usually easy to replace but probably require access to the back
of the oven.

Thanks, that makes sense as it is normally open. Mind you 230 centigrade is pretty hot!
