I have a SMEG oven (model SE378MFX5) which is about eighteen months old. It has been used quite a lot and I have mostly only used the fan cooking option which relies on one of three elements which is in the centre of the oven. About two weeks ago this element stopped heating up so I carried on cooking using the upper and lower element options until I could get a replacement for the fan element. That was okay until I went to use the oven on the weekend and it wouldn't heat at all. The main oven light comes on and there is a lower fan which was turning okay but the centre fan wouldn't turn and the orange heat indicator light didn't come on either. Could it be the thermostat? I am not going to try to replace it myself but would like a heads-up if possible before bringing in an engineer.
I would be very grateful for any advice,
