Cannon Range Cooker electric oven and grill overheating

[Kerans]

We have a Cannon Dual Fuel Range Cooker 10450G

The electric main fan oven and electric overhead grill - which is on the same side above the main oven - have started overheating, in that they are always on absolute full power; the thermostat/relay on the oven never clicks off, no matter the knob position.

I originally though thermostat failure but don't understand how both the grill and oven are affected, are they likely to share a thermostat? Or could it be an "energy regulator" that I also see as a spare part - this seems to be part of the control knob, so I'm also not certain whether I'd need to replace two knobs or one. Maybe it'd become clear on disassembly but would rather order the parts first in confidence.

If anyone knows what I likely need it'd be much appreciated, I've replaced a few parts in it previously, so reasonably confident.

Not 100% sure but it sounds like yor grill may be working normally but your oven regulator has failed as you suspect. If the grill was overheating then the overheat stat woulld trip and switch it off. Does it have a selector switch that turns it on/off independantly.

Hey thanks - the grill and oven each have their own independent knob, and they are separate compartments.

It’s possible that inside they share some common component, maybe thermostat or regulator. But the pics of regulators I’ve seen look like they are part of the knob assembly which is confusing for me.

Maybe two components have failed at once, it’s just annoying as the whole cooker is due to be replaced in a few months. It must have heard us talking about it…!

Update - the grill is actually fine, we were just hypersensitive to the idea of overheating I think as the first problem with the oven caused a lot of smoke!

So it’s either the regulator or thermostat of the oven…?

As #2. Regulator failure is common and usually mechanically obvious on inspection.
