We just had a second compressor on our walk in cooler fail in just over 2 years. It is 5 HP, 480 V, Copeland compressor. The condensing unit was purchased new and installed by a pro 2 years ago on our approximately 6000 cubic foot box.. The first/original compressor failed in February 2014, just about a year after purchase/installation. The second one just failed now, a little over a year after the first. The first was replaced under warranty but I am paying $2500+ for the new one now because the warranty is up (over a year).
Over the past few weeks I noticed that the compressor sounded louder every time it ran. Some others thought I was imagining it so I didn't think too hard about it. Now I realize that was likely an early sign of it's demise.
Any ideas what is going on? The refrigeration guy said the piping is correct and the lines have pressure and he did not think it was an oil issue. He speculated that it is something with our electrical service.
