Yeah, my guess is belt (hopefully) or maybe a broken gear. Seems like the motor is fine based on the sounds its making.

If you decide you don't want to wait until December, I'd be willing to take a crack at it. Electronics repair is a hobby of mine and I live in the Parkrose area.

Oh weird, it still shows up for me. Maybe you can search for it.

I get these when I'm stressed. 99% of the time they're painless.
