Trouble with flat beer

[Charles2804]

I've just made this a month and half or so :

At first, it was difficult to set the right with the ****ty thermostat so i built one digital.... but for 3 weeks beer temperature has variation between 32-46F at 10psi, one of my beer was foamy (cream ale) and couldnt poor a glass, the other was a brown ale set at 10 psi also and was ok but never fully carb.

2 week after i tought that the cream ale was overcarb so i cut off the gaz and reset it at 8, I purged twice. For two week, foam was going away slowly and i'm now with a flat beer but it been 2 week at a stable temperature 35-36F at 8psi. FLAT so Ive put it at 14psi for a week still flat.....

MY brown ale seem to loose carb with time... it is a little more carb than the cream ale (flat) but still....


Could it be to much variation of temperature? the beer may also maybe freeze once in the keg?!?! I check for leak everything seem ok, and I donbt think so it could be the promblem because at the beggening the beer was foammy...so with carb in it?!

thanks

Well that is an odd one and I think I kind of follow.

How long are the liquid lines from your keg to your tap? How thick are the liquid lines as well?

Are you still having huge temperature swings? What temperature control do you have? You say that beer is going flat. Are you sure the kegs are sealed up at the lid? Beer in a keg that was carbonated doesn't just go flat. Gas has to escape from somewhere. Are the gas and liquid lines connected to the right posts?

open the keg, the beer was frozen
