Product review (1 stars): Loud popping noise
We are having the same popping (aka gunshot noise) that other reviewers have mentioned.  We just received the kegerator last week and put it together, within a day of setting it up the noise started.  It occurs about every 30-60 min, some of the pops are quieter like bubble wrap and some are much louder more like a gunshot.  It is in our entryway and we can hear it in the bedroom, even with the doors shut.  We've reached out to the manufacturer who hasn't started off by being very helpful and offering solutions, they said this is the normal part of how the kegerator works but she agreed she would speak with her boss on Monday to see what they would be willing to do.  She said if we do return it we would have to pay $120 shipping...
We've reached out to Amazon as well who was very helpful, so no complaints there.  But the manufacturer doesn't seem to be acknowledging that multiple people have had this same issue and doesn't appear concerned in resolving the issue.  I would not purchase this kegerator.  When I read the other reviews on various websites that mentioned this issue I laughed and thought they were being a bit dramatic, but having heard this sound consistently over the past several days I know understand and it is highly annoying.
