What would it take to build a cryogenic cooler?

That doesn't look like a capacitor but a thermal overload for those rechie's. Capacitors will have a uf or mfd rating.

I don't know anything! I just saw something and thought maybe I got the capacitors after all. I know someone else who brought these same compressors had complained about not being able to find the right ones. So when I saw these things, I thought maybe I got lucky. But then, I'm rarely ever lucky!

When the time comes, I'll be asking you guys how or where to install them. They seem like they go on the top of the unit. So the capacitors must mount remotely from the compressors themselves, huh?

Hi guys! I was wondering where you all have been.
