We bought this single wall oven for our new build that we moved into mid October. I have mostly only used the bake function for baked goods (cookies, muffins, cakes etc) which has been somewhat frustrating due to many items turning out too dark therefore have had to reduce temperature and cooking times.   I hadn't tried convection bake until today but after reading another reviewer's comment about the fan I gave it a try and sure enough mine has the same issue with the fan running during preheat but turns off once reaches temp.  I watched it for 10 minutes and it didn't turn on once.  Argh... how disappointing that it's yet another issue I have to deal in our new home and am worried about the amount of hassle I will have to go through and whether it will even be able to be fixed as the previous reviewer indicated multiple units had the same issue.  Clearly this is an issue with this "Wall oven with Total Convection".
