To replace the cooling fan which is located on the upper back left of the oven, it required removing the oven and 3 metal panels. To remove the oven the best way was to remove the oven doors first which will reduce the weight significantly. Once I did this it was much easier to left the oven by myself and move on a self made stand. After the removal of the metal panels there were 4 screws to remove the metal plate holding the fan to oven, 2 electrical plugs, and then another 4 screws to remove the fan from the metal plate. After a little cleaning to remove some grease and replacing the fan (also replaced the Hall Effect module but I don't think this was bad), it was easy to put back into the oven reversing the process. Also please remember to remove power during this process.
