Here's the stats:
Summit kegerator
Tower blower installed
6' of 3/16" line bought from a brew shop
1/2 keg of Dogfish Indian Brown
Beer temp 37-38 degrees
leak tested repeated with no leaks currently

I bought the keg in late January, hooked it up and cranked the kegerator temp down (it's an old hand me down and has had problems getting cold), set the PSI to 13 waited a day, first beer a little foamy immediately followed by a perfect one. Ran like that for almost a week then my newly filled CO2 tank went dry. Turns out I had a leak in the regulator. Took a couple days, but refilled the tank, fixed the leak after reading some threads on this forum.

While reading I found the magic 38 degree parameter. I didn't have a thermometer at the time so I put a glass of water in the kegerator. Checked it the next morning it was frozen solid! Whoops. Lowered the temp and bought a thermometer, now I have the temp in water glass to 37 and the foam coming out the tap at about 38.

So there's the problem. Once I got the temp up, I get nothing but foam, 100% thick foam. I very thoroughly cleaned the coupler, beer line, shank and faucet with beer line cleaner. I have over the last couple of days ran the psi up from 12 to 18, venting the get between changes and letting each setting sit for about 12 hours. I do see bubbles form in the beer line. I did the leak checks, checked the keg head - it looks brand new. Read the FAQ's here about temp and pressure. The pressure article says that both low and high pressure can result in foamy beer, so how do I know which I have? I have a call and an email into Dogfish for their temp and pressure recommendations, but no answer yet. Thoughts?
