Refridge question

Our 1975 Alberg 37 still has its original (c-1976) Adler Barbour 'Cold Machine' (air cooled) which still works great. Only problems we've had occurred years ago, when the unit needed recharging (sent the compressor back to A-B and re-installed it), and the 'electronic unit' failed (again years ago - replaced it with a new one). However, I fear that the evaporation unit (the aluminum 'glove box') is becoming somewhat pitted, and think that before long, a hole will develop and the freon (R-12) will leak out.

That being said, several years ago, I bought another A-B unit at a flea market for $5.00 which looks like new, but the owner said 'it won't run'. Since the 'new' compressor has the same 'prong' arrangement (it's a BD-35) as my old one, I took the electronic module from the 'flea market' and tried it on my old C-1976 machine, and my old refrige wouldn't run with the substitute module - which I took to mean that the 'flea market' module is bad. I've toyed with the idea of taking my 'old' working module and installing it on the 'new' compressor and see if the 'new' compressor would run... But I'm a bit leery about taking my good module and testing the 'new' A-B compressor. Any thoughts whether I could damage my good module.....

Also, I've considered exchanging the 'new' evaporator (which appears to be perfect) with my existing evaporator (the one developing pits), except for the fact that the 'quick disconnect' fittings are different size than on my existing system. I know I could probably unsolder the fittings, and substitute and resolder the new fittings, but that job is probably best left to a refrigeration 'expert'... Also, neither of my compressors have serviceing valves...probably another reason to leave the job to an expert. (I have Dick Kollmann's '12 and 24 Volt Regrigeration Manual).

Thanks for any thoughts (I'm CHEAP!)

Re: Refridge question

Why not send Kollman an email asking him your question?
