Well, I received a Danby as a gift this January from my loving girlfriend and as an engineer, enjoyed the challenge of getting it dialed in. Originally I started with the resistor mod, and while this helped, it didn’t cure my issues, plus, in my mind it was a quick duct tape fix for a larger issue. I ordered a standalone control similar to the ones posted in this thread and took over control of the units cooling from the Danby. The result was remarkably consistent temperatures, wherever I felt like setting the temperature.
I still had foam issues, and pilfered a small 12VDC fan from a computer power supply and mounted it in a box. I ran some ¾ inch tubing up to the top of the tower to improve overall cooling. In my opinion, one of the large issues is that as the beer warms while it sits in the tower, the CO2 separates from the beer, creating lovely foam until such point that I am drawing cool beer from the keg.
As it is now, I get inconsistent performance. Some days with a fresh keg I will pull perfect first beer pours. A few days later, I’ll come by and the keg is foam central on the first pour, and if I follow it immediately, I’ll get a clean second pour.
I’m beginning to wonder if the coupler or regulator are bad. And as much as I love to blow money like the next guy, I’m curious if anyone has any theories as to which it may be. There was one post in here already that indicated replacing both helped, but they weren’t not sure which piece individually it was.
Other items I may also look to include a larger fan, larger cooling ducting, larger opening for the tower, and new insulation. I appreciate any other theories.
Thanks!
