I had a service guy look at my stove two weeks ago as it just didn't seem to be working right and he decided the combustion fan was weak so he ordered a new one. A few days later the convection fan starts to grind some so I called the service guy and he added that to the order. It was all supposed to be in in a week, but as with everything surrounding this stove nothing has gone as planned. Yesterday I lost the ability to control the convection fan. It appears to be stuck on high so I guess it cant damage anything, but still its stuck. Acording to the manual its either a faulty control or a faulty override sensor. I pulled the purple wire of the sensor located above the combustion fan and still had no fan control. If I am reading the diagrams correct that is the 160F sensor and the problem is in the switch. Can sombody tell me if that is right? I will call the tech in the a.m. and add another part to the list to be replaced. I am starting to think I just need a new stove. These are pretty simple appliances there really isn't that much to break. There are only really three major moving parts and I need to replace two of them, and now I have electrical gremlins which is never good. This project has been a disaster from the beginning, and for the money I jave laid out I would expect A LOT more. My dealer is out of business so the service guy works for a dealer I didn't use.
