Default Ranco is at 30 beer is at 42 and still foaming.

How do I get the Ranco to accurately regulate the temp of the beer. Right now the beer has been in the freezer for 4 Days. The Ranco is set at 32 with a 2 degree dif. The beer however is 42 degrees and foaming like crazy. Will 42 degrees make the beer foam and if so how do I get the Ranco to regulate the beer temp more accurately?

Where is the sensor located? If it is touching anything, it may be giving inaccurate readings.

Beer shouldn't foam at 42. Give us some more vitals on your setup like liquid hose diameter and length...taps you're using...etc.

As far as the thermostat setting, I never trust those things. I always place the thermostat probe next to a digital thermometer probe inside the unit and when the digital thermometer hits the temp I was shooting for, I dial off the thermostat just enough to click off the compressor.

32 is pretty cold... Most folks would say to serve around 45 degrees. If you're foaming like crazy at 32, you've got a few things to consider. What PSI are you serving at? How long are your lines? What's the ID?

I'd recommend getting longer lines, or smaller diameter lines. I use ~8-10ft of 3/16 ID hose and don't have a foaming problem. Also, if you're using a picnic faucet, make sure to open it all the way.

I serve all my beer at 42F, zero foaming issues. Your problem lies elsewhere.

I have 3/16ID Bevlex hose 12' length. I have tried to serve it from 4psi-12psi no difference in foam. The ranco probe is not touching anything. I have had it off gas with all Co2 purged from the kegs for 3 days to lower the carbonation in the event if was overcarbed. The probe is set to 32, the beer/foam poured is 42 degrees. Standard style taps out of a tower. First beer pours like all of the rest... Foam.
So there are the vitals.

What were your carbing and off gassing procedures?

I carbed it at 35psi for 24 hours. It foamed so Like I said, I turned all of the gas off and purged all of the Co2 from the kegs for three days.

Is this just the first glass you are having foaming issues with?
