Hi – my first post on the forum.
I have a Smeg A2-8 cooker about 7 years old – two electric ovens and a gas hob.
The main oven has stopped working on all 8 settings, with no heat to any of the 3 elements, the circulation fan not spinning, and the light not coming on. However, the casing cooling fan does operate on all settings apart from defrost (I guess that makes sense).
I’ve set the time on the clock. The thermostat clicks as you turn it up towards 50 oC but the neon light doesn’t illuminate.
I’ve checked the resistance on the elements and get 30/50 ohms on the upper element, 42 ohms on the lower element and 25 ohms on the circular one. That all seems pretty reasonable to me.
Posts elsewhere have implicated the selector switch, but I’ve removed this and can’t see any sign of heat damage or arcing.
As an aside, I’ve re-fitted the interior lamp and this does now come on when the door is opened. I’d previously removed it because it was on all the time, but I can see now that the microswitch needs a tweak.
Any suggestions would be appreciated.

At a guess I`d say the overload stat has failed. I am not familiar with your model. You`d have to remove the back WITH THE POWER OFF 1st (!). You are looking for this: 818730424 so google this part number to get a picture – a little round part with 2 tags- so you`ll know what to look for.. This might be the part you are looking for but I cannot guarantee this is the correct part number. If that has gone open circuit, wires to it burnt off OR looks ok visually it has probably just gone open circuit so test with a meter – Do Not bypass it by joining the wires together. The stat should be somewhere near the main loom from the mains terminal block.
If the wires to it are nuked, cut and retag. If the wires are ok but the o/l/stst has open circuit it either failed because it wanted to or failed because the area overheated. The stat should be near the main loom from the mains terminal block as a rough guide.
