What Keeps Freezing My Beer

[PostModern]

If it is indeed freezing through the bottom of the keg, could you not just raise it slightly to get some air-space underneath? That is if raising the temp isn't an option re not being at your desired serving temp.

Came in to post this. My keg fridge is a freezer at the bottom type and the bottom of the fridge section gets bloody cold. I have a small metal frame sitting in there to raise the kegs a few cm and keg freezes are a thing of the past. No matter what temp the fridge it set to, the freezer is minus 40 or something, so a keg can't help but freeze.
