cant find this as a model ; check timer first . ( often smeg ovens have a door micro that operates the cavity lamp so this may be a seperate issue ? )
other than that, agree probably selector switch …. full model will be handy
It was hard to pull out, stuck with crud, so I pulled on the door to get it out. The door came off in my hand, and was difficult to get back on. Customer said he never uses the timer, thats what made me think off selector switch.
There was also a transformer in the top, but couldn’t see what it was for. That’s why a wiring diagram would be handy
