Oven smokes when in bake mode but not in convection mode. I believe the cause was being overloaded with pork roasts (husband roasted 5 roasts at one time). Self cleaning didn’t help. It has been this way for a year, so I have been using convection only.
I cannot find much info on this make and no info at all using the given model number.
I am assuming that the unit has separate bake and convection elements since the convection does not smoke.
You are going to have to check/clean the bake element and the area around it.
I did see on the Fulgar site that units have a hidden bake element so it may be a chore getting to it.
