interchangability

[AV8RSVT]

I purchased a La Crosse 81 pepsi machine I also found another machine not a lacrosse the door on the left side. The front had some simulated wood grain looked to be a mid 70's machine? My question is are the refrigeration units interchangable. Mine is having some series issues (popping breaker when comp turns on). I want to pull the complete unit out of the other machine and install it into my LaCrosse, I dont even want to evacuate it. I really like my LaCroose better.
