Uhh? ... snip Roland, Dave, Ray, thank you for your replies. We have had a neighbor in the HVAC business top up the R-12 and have gotten away with it for quite a few years. The unit is a Sub-Zero 532 built-in, so it would not be easy to replace with a standard box. > https://appliancebuyersguide.com/sub-zero-532-replacing-an-old-or-broken-subzero/ I have been researching the Net to learn how to convert to R-134, find leaks and replace the evaporator (normally > $800, part ~$110) myself. After watching a few Youtube videos, I am now an expert :). This seems to be the best resource so far (click the Look Inside to see the good stuff): > https://www.amazon.com/Refrigeration-Conditioning-Technology-John-Tomczyk/dp/1305578295 Good videos: https://www.youtube.com/watch?v=pCv7rCdcXsc (a few in series) https://www.youtube.com/user/KenTraining/videos (interesting channel) I figure the worst case is, I buy a modern used refrigerator and transfer all the bits to the S-Z. After I acquire all the tools, I can also fix the Explorer and a window unit. I'm also thinking it would be cool to add a Linux IoT WiFi thingie with a bunch of sensors to monitor... well everything. The original refrigerator didn't even have a thermometer. I only knew things weren't going well when the fresh veggies went bad after only a few days. I'm keen to fix that. Sorry if this is noise. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
