Good morning sorry for the delay.
Do you mean the metal shelf, when you say the side panels fell off?
If so these have little latches\lugs which fit in the holes on the side of the oven, if you look you will see on the side of the oven holes about 5mm wide which match up with the shelves, if they dont check your looking at the right side as the shelves are designed as either right or left.
The light cover in the main oven is removed exactly the same as the top oven, if the cover is stuck this is most likely due to baked on grease, smear some oven cleaner (such as over pride) around the cover to help break up the debris, using a cloth grip the cover and give it a couple of short sharp turns anti clockwise and it should free up.
Please let me know if you need any further assistance or clarification.
I havent heard from you in a few days, and wanted to understand if I can be of any further assistance?
Good evening, I havent heard back from you in the last few days, do you still require assistance?
