HELP Frozen CO2 Tank

[tobrew]

Went to get a glass of homebrew about an hour ago everything in fridge looked OK..Went down to get another brew about an hour later and my tank looked like a big piece of ice.The gas lines even had ice on them..What would cause this????
It was a full tank as of yesterday.Fridge temp is about 40 degrees F
Thanks

A fast leak would empty the tank and cause it and everything prior to the leak to ice over.

A fast leak would empty the tank and cause it and everything prior to the leak to ice over.

That's the only thing I could think of, too.

Ditto. The tank is probably empty or almost empty, done so at a RAPID pace.

If there is any gas left, find the leak now, then go refill.

Yep. Leak. Been there.
