Re: SMEG DUCO8SS Lower Oven Not Heating
What does the oven do? Fan on, light on, cycle lamp lit? Far and away the most likely culprit is the fan oven element.
Potboiler on the nefarious habits of fan oven elements can be found HERE; replacement element is HERE.
There is a one-shot safety thermostat on the rear of the oven, p/no 818730567. spares@ukwhitegoods.co.uk will get you one promptly if required.
Stay safe, power off when working on the oven.
