new whilrpool microwave built in

2 months old. Turntable developed a metallic sound when it was initially turned on. for about 3 times. Now turntable doesn’t work at all. The parts listing for turntable shows a few parts from unseen to the visible removable parts.

It looks like a removable plug in motor type part that might be the problem.
It is a do it your self task? how difficult, Is there a schematic step by step tutorial somewhere?
