Got my man Litao with me changing this 92K BTU compressor for a walk in box today. This compressor shorted to ground and the oil has carbon inside. We will be performing an acid test and adding in a suction clean up drier (for acid and burn outs) as well. I did find it interesting to see corrosion around the compressor pins, I would presume from the compressor sweating as times. This might be the root cause of compressor pin blow outs I see too often. Moral of the story, check oil where possible, perfrom an acid test and add a burn out drier to clean up the system. #teachme
