If anybody has answers for any part of my question I would appreciate your help.................................
I have a Danby model DCK644BLS. It is a direct draw with a 3 inch tower. The unit has a digital thermostat that can be set from 36 to 41 degrees. I keep it set at 36. The read out displays the actual cabinet temperature and will range from 32 to 40 degrees depending when the cooling cycle had run last. I have a problem with a lot of foam on the first pour. I think it may be because the tower doesn't seam to cool very well. If I pour several in a row they get much better after the second. Like I said the tower is a 3 inch tower but the hole leading through the top of the cabinet is only about half that size and I don't think the cool air is able to get up there. I know that micromatic sells a blower model 2C782 that looks like the right kind for my kegerator. If this one would work how do I wire it in? I also noticed that it has 3 holes for mounting it. Does this mount right to the inside of the cabinet and blow air up the hole with no other hoses required? Is there a hole that I'm not seeing to run the line up through the blower unit?
Thanks in advance for your advice!
