Both the upper and lower elements
Model number from book for built in wall convection oven model 800264
The model number on the namplate of this oven is 800264
I unscrewed the screws and something is holding it from pulling out!
It only pulls out about 2 inches, and the wires are screwed onto the element. It also looks like possibly a ground wire to a plate also.
Why do you say this is not the model number when it is stamped on the nameplate?
I was able to figure out it is a lot more work than your original answer.
