No matter how long it is left on our Diplomat ADP 5330 oven heat up to above 160°C. On looking at similar posts it seems this might not be the thermostat?

Any ideas? Grill element working fine. Could it be cooker elements on the way out? We could buy part and have mate install it hopefully.

Please help - there are only so many things we want to eat from a pan!
