Here is the story: Both my boyfriend and I bought a Kegerator, and we had a small issue in the beginning with the copler not working, and we ended up borrowing our friends copler to get the keg to work until we got our new one, which now we have. Since than we killed a pony keg and we decided a 2 weeks ago to get another one, to try our new copler. Things were great for about 2 weeks, and now all of sudden the beer doesn't taste right (taste skunked), that make no sence. So I ended up cleaning everything the tubes, and is still taste like skunk, there is no way that the keg has already pass due. Not sure what we are doing wrong, I've look on-line for everything, and the pressure is right the temperature is right and I cleaned it. Well I don't want to waste a keg. I might try to clean it again today. Anyone have a suggestion why this is happening??

Please Help!!
