Fixing the fridge: Alternatives to DOMETIC CU-94 and VD-14N?

[Krumelur]

Back in November I ordered a DOMETIC CU-94 and a VD-14N. I got a good price, I think: €590 for the CU-94 and €370 for the VD-14N.
The problem is that I still haven't received parts (by the way, same is true for the JABSCO toilet - different seller, same issue).
Now, with warmer days approaching, I really want my fridge to be fixed.

What other unit(s) could I use to replace my low-powered original devices from back in 2010?
