Smeg Range Cooker Oven None of the three elements heating

[TD129]

Hi, I have a Smeg SUK92MFX5 range cooker where NONE of the heating elements are heating up in the main oven all of a sudden (small oven on the right hand side is working fine).

Temperature dial light is coming on and fan is spinning but NONE of the three elements area heating up (grill element, bottom element and fan element) on any of the settings.

We really only use fan oven mode and I have tested fan element on multimeter which is showing a 26 ohm reading which I believe is normal.

Main oven thermostat and bottom heating element were replaced 10 months ago. Theromstat light is coming on and I can hear the clicking sound when turning it I have assumed that can’t be the problem. I am not sure what would cause all three elements to stop heating all of a sudden.

I know it is not the clock timer stuck in auto mode because otherwise the fan wouldn’t spin.

Anyone have any ideas of what else I can look at?

If it has a small relay pcb on the back that’s what supply’s power to the elements so I would check that

i would check the multi function switch

I did look for a PCB on the back but I couldn’t see one. I am not seeing any PCBs on any of the spare part websites either.

Thanks for the suggestion Dave. I was going through the parts available for this model after making this post and I was thinking this is the only other part that could be responsible. I assume the part is https://shop.ukwhitegoods.co.uk/811730316-main-oven-control-switch

The selector switch seems to be working enough to spin up the fan but none of the other heating elements. Before ordering this switch are there any ways to validate that this indeed is the faulty part?

I assume replacing is similar to the thermostat module as it is right next to it? Looks like there will be many more wires connected so I just need to make sure they back in the same position.

first check it as there will be a faulty contact
