Re: Smeg Range Model suk91mfx5 Error code FU14
there are no error codes on that model, its a simple dual fuel range with no electronics other than a relay pcb at the back. assume its just a faulty clock. could have a guess what the FU means though.
You have not mentioned if the oven is working or not? worth by passing the clock temporarily just to test it out if not. 816290735 is the part number but if before 2007 you may need a set of knobs as well.
