I immediately went on the google for answers and came across a topic at Cheap Ass Gamer started the same day:

Where someone shared the insight:
I also sent an email to oldschoolgamer (the guy/site who does retro game system repairs) and was told they no longer service model 1 Sega CDs.Sega CD 1's that keep ejecting can be:
1 - Closed tray switch not being activated. If they've been taken apart & not put back together properly, the limit switch never gets tripped. There is a large timing gear with little plastic nubs that activate the limit switches. This can also cause it to recall the tray for no reason once opened - if the open switch never gets closed.
2 - Stretched belt on laser mechanism. The initial Sega CDs have a bad design that swings the entire large laser assembly down to load a CD. When you push the tray in, the mech swings up, locks in place, and engages the CD. If the belt is old / stretched, it can't make it the last little bit to lock it in.
Now, in the CAG thread the guy said that when in place everything in the Sega CD actually worked, so I'm looking at where to go from here to get mine working.
