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.
