Thanks to Owner-Manuals.com! This manual was exactly what I needed. As Amana was purchased by Maytag and later by Whirlpool, there was no way to receive it from their websites. I was lucky to find this resource.
A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.

Inserting the shelf, baking tray and roasting pan
3
Anti-tip device All insertable components have a small curved indentation on their left and right edges. This indentation serves as an anti-tip device and must always point towards the back of the oven. Inserting the baking tray or roasting pan: The anti-tip device must point towards the back of the oven.
Inserting the shelf: Insert the shelf so that the two guide bars point upwards. The antitip device must point downwards and be at the back of the oven interior.
Inserting the shelf and the baking tray or the roasting pan: When using the shelf and the baking tray or the roasting pan together, insert the shelf�s anti-tip device exactly into the indentations in the baking tray or the roasting pan.
