Kegerator temperature varies greatly

[shawnco67]

When on the coldest setting, my kegerator will get the air temp down to 32-33 degrees (measured in the blower hose in the tower). The compressor will not kick back on until the temp gets up to about 39-40 degrees.

The kegerator will warm up to the 39-40 degrees in about 20 minutes. The stainless top is cold to the touch. Could the fact that it warms up so fast be why the compressor wont kick on sooner? Is there an adjustment in the thermostat to make it start at a lower temp? Turning the dial down affects the lowest temperature, but not the higher temp. I want it to kick on at 38 degrees.

It's a beverage air bm23.

Thanks for any help.

While your air temp is important, you should be more concerned with your liquid temp. It is your more important number. What is the temp of your beer?

[shawnco67]

With it set on it's lowest setting (ranges from 33-40) the beer in the keg will get down to 37 degrees. This is measured by pouring a glass and then pouring another glass.

My problem is foamy beer in the line. I was thinking that perhaps the range in temp is what is causing this. Maybe I am wrong yet again.

For the first beer of the night, if I pour off about 1/2 glass of foam. The next two beers are poured near perfect. When going for a refill, it is foamy again.

Perhaps I should raise the temp so the range is smaller and the beer will get to 38 degrees, this would be less up and down for the beer in the line. Any ideas?

Does anybody else know what the air temp in their kegerator ranges from? High to low?

Thanks.

If your first beer is foam and the next ones pour fine then perhaps your tower is not cooling as it is supposed to. I assume the Bev-Air BM23 has a blower motor and hose forcing cold air up the tower assembly. Check to make sure this blower is working and the hose is headed up into the tower.

The blower is working and the hose extends to the top of the tower. The tower is also insulated with foam.

i don't know what type of thermostat is in your unit but i would check to see what the cut-in and cut-out setting is it seems as if there is too much of a differential setting there i would try to keep the diff at about 3deg or so. when you had it set to the lowest setting were you still having a foam issue. the coldest point in the system should be at the back of the faucet shank anyway

[shawnco67]

I adjusted it a little higher and now the range is about 36 degrees up to 40ish. A glass of water in the box right next to the door gets down to 37.5 degrees.

I still had foam even with it on the coldest setting.

How do I check the cut-in cut-out setting? Is there a way to adjust? I would love for it to go from 35 to 38. I think that would solve everything. The thermostat only has a dial on it that goes from 0 to 9 or something. I don't see any other adjustments.

Thanks for the help.

What is the pressure you are applying and brand of beer? Also, is your condenser clean?

[shawnco67]

I just got my new regulator from MM. I have it set at 15 psi with Miller Lite. I live at about 5000 feet elevation. I have 7' of 3/16" hose.

Where is the condenser? I cleaned out the coils in the back. They are still a little dusty, but not too bad.
