My wife and I live on a small sailboat. When our refrigerator and freezer began to have problems, we sought the help from a recommended refrigeration technician. He said he needed to remove everything to bench test at his shop. After two months of living out of a cooler and no answers to our phone calls/texts/emails, we threatened with legal action. Shortly thereafter, he returned everything to us - in a box!&nbsp;I was able to hire another technician to put most of it back together, but he can&#39;t figure out how to make the water pump work.</p> </div><p><a href="http://ecmweb.com/forums/general/general-electrical-talk-discussion/two-compressors-one-pump" target="_blank">read more</a></p> http://ecmweb.com/forums/general/general-electrical-talk-discussion/two-compressors-one-pump#comments General Electrical Talk Discussion Sun, 01 Jan 2017 00:23:16 +0000 143831 at http://ecmweb.com
