Older Beverage Air BM23 Beer Tower Diameter

[cubalz]

Hello all! I currently have an older BM23 with the triple taps and black sides that I would like to replace the beer tower. The problem is that I am at work and I am not sure what size it takes and I do not want to drill new holes. I think it is 3" but am not sure. Can anyone confirm?

Never mind, I called Beverage air and got a primer on how to measure the tower "bolt pattern"

Hey ALL! I’m new here and to owning my own beer on tap system at home. I recently purchased a Beverage Air BM23 for $200. The evaporator fan I noticed is not turning. When I plug it in the cooler does get a bit cool but not where it should be. Any suggestions on what I should do here? That seems like it’s the only problem I’m having. I’m pretty ignorant to hearing and cooking also so I apologize in advance for sounding dumb! Lol But, I’m sure it needs a shot of r134 also right?
