I kegged my APA tonight and all seemed fine. I set the psi to 15, burped the keg a few times and put the keg in my fridge. An hour later I checked on it and the psi was at 0, the co2 tank was covered in frost, there is seemingly no pressure coming from the co2 tank and no excess air in the keg (when I burp it nothing happens). The temperature in my fridge is 33 f, a little on the cold side I know but it shouldn't matter right?
I had my tank filled up a couple of weeks ago and haven't touched it since.
Did the temperature in my fridge do something (make me lose all my co2 or break some of my equipment)? Should I Assume that my tank didn't have as much co2 as I thought it had? It's 20oz so I would have thought it would be enough for a few keggings assuming it was full.
Any suggestions as to what is going on?
