Re: Smeg SUK60MFX
I was correct in narrowing it down to the relay component. On removing the cover I found It to be a thermal relay which operates the top fan when the relay gets to a set temperature (that’s why it is hot to touch)and switches off when cooled. This explains the delay in the fan stopping about 10mins after the oven is switched off. The contacts are permanently open. I did test the fan by bypassing the unit and it worked OK. I have contacted Servevast to try and get one.
