Cool, I can manage that.

Here is a complete how-to by some unknown dude.

Good to know and definitely a consideration, thanks!

Good to know, but even more importantly, WELCOME BACK! I saw your post about a week ago, I think, saying that you were back and doing better, but this is the first post that I've seen other than that. It's GREAT to see you active on the board fella. I really hope that you're doing well (or at least much better and still improving).
I'm going to setup a gofundme to get you one of these so none of us have to go through this emotional rollercoaster again.

I’ve taken things like this apart a lot, usually break some fasteners and have to get creative about re-attaching the cover, and almost always have parts left over, but I make them function. Ten weight oil like good old 3-In-1 should work fine. You don’t need to worry about “food grade” on the fan bearings. That doesn’t look like the fan in the food cavity, it looks like it’s there to cool the electronics.

So you're saying that it's not drying to a dry film, possibly some sort of thinner that makes it easier to spray, and then it dries to a wet film of lube?
Yeah, there was a guy. The main issue is that there are a couple of screws that require something like 18" long small sized screwdrivers to remove.
The fan in the video is not the main fan. The motor has shaft sticking out both sides. One end has a fan mounted inside the cooking compartment to move the air around in the oven. The other side, as you say, has a small blade applied to keep the motor and stuff around it cool.
