Smeg SUK62MFX5 – Oven fault (will not heat)

Re: Smeg SUK62MFX5 – Oven fault (will not heat)

Evening Greg,

The main oven doesn’t have a cooling fan only it’s main fan inside the circular element, it has a small hole (the size of an old half-penny) at the back which feeds an exhaust type shoot which screws to the rear casing – I can’t find a fan. There is a cylinder type fan on the upper oven/grill which DOES switch on after about 10mins, it blows air up upwards out of the top of the cooker unit.

Earlier, I took the rear cover off, reseted all temperature sensor connectors and let the unit run on maximum 245oC…..I made the area safe, nothing was touched inside the unit. The unit ran consistently for 45mins at maximum temperature – no faults, remember the rear over was off. I then turned it off to let it cool.

I’ve just put the rear cover back on and then switched on. I ran the unit upto say 230oC and it then cut-out as it did before. The timer display went blank, the upper fan stays spinning and warm air is being expelled from the top grille.

So do you think something is on the verge of reading a temperature fault? The original fault of no heat at all seems to have been fixed, the stat is switching as expected – I’m now left with this suspect overheating issue.

I can’t see any other fan that should be spinning to keep the chassis area cooler where the sensors are.

In fact as I type, the unit has cooled sufficiently that it has ‘clicked’ and the LCD is now flashing – the unit will now work again.

Any ideas Greg?…..thanks for your help

Evening Greg,

Sorry it’s been a short while since my last message……slowly but surely I’ve been trying to identify which thermal cut-out has been causing the shutdown….it turns out, having bought an ‘oven thermometer’ from a hardware store that the Smeg is ACTUALLY overheating and the thermal-cut out responsible for the shutdown seems to be working OK.

I therefore think after the original fault at the top of this thread there has been damage caused to the thermostat (which I hoped I’d get away with 😥 ).

Now, when the unit is set at 50oC the oven heats to 200oC – leave it at that temperature and the Smeg will stay around 200. This of course is OK until my wife wants to cook a rice pudding at 100oC 🙁

So it looks like I need to replace the thermostat, could you therefore please tell me:

* If on the face of my comments above, you agree with me?
* I take it a replacement thermostat will comprise of the actual switch and knob assembly + the long wire to the probe in the oven itself?…will that be part of the stat itself?
* If I can buy one from you guys or your preferred supplier – just need the partcode if you don’t mind and I can call/email them – any ideas how £much to expect this will cost?

Thanks again for your assistance

Thanks Penguin45,

I’ve sent an email to the address you state above…..just one thing though, I’ve found a picture of the Smeg partcode you mentioned above – mine is completely different?…

…the part I require is much longer, more spade connections, mostly black in colour and the thermostat in encased in a black plastic shroud.

Would you mind checking the partcode please Penguin?

Many Thanks – again….
Gary
