I'm on my 10th keg since I built my kegerator and up until now everything was great. Now when I open the faucet, I get a shot of good beer then a slug of pure foam then good beer. The head used to be 1/2 - 3/4" now it's ~ 1-1/2" and a little crusty - not creamy like it should be.

Beer gas (75/25) @ ~ 32 psi. Temp was a little low @ 35 but I've adjusted up to 38. Lines, faucet & tap beer-cleaned after every keg. Beer gas bottle sits in the fridge w/ the keg and I recently upgraded to a larger bottle - 10# to 20# (although this is the second keg on this bottle and 1st keg was fine).

Could the gas bottle being in the fridge be causing the problem? Nit & CO2 separating?
