kegerator fobbing

[bigdave]

My kegerator was working fine a week ago but all of a sudden it seems to have started fobbing uncontrollably?

Its a polykeg with sankey connector, connected to about 2m of 3/8 line, reducing to about 5m of 3/16 line. I usually condition and then dispense at about 20-25psi (lager 30-35) without a problem but without warning I cant even dispense at 5psi!

Assuming that I'd somehow over carbed, I've depressurised and reconnected the keg then slowly gassed up to push the beer through the line but even at 2-5psi, its just foam!? Its kind of surging, so I'll get a steady stream of foam, then a glug of foam then repeat.

I've disconnected and re-connected everything with no joy!? I've even tried a different keg and varying temperatures with no success.

It will take time to depressurise as the CO2 is dissolved in the beer and will take some time to come out of solution.

Could be the cold weather affecting your setup depending on the location of your kit.
