I have a similar (I think) problem with the Menard's "Vetter Sash" building. First, let me say it is a terrific structure, large and very detailed. My problem is that like the gyrating part of the power plant, the window fans have stopped rotating. I believe that the motor still runs whenever there is power to the building, but no spin on the fan blades. Does anyone know whether the fans run on a gear which may have broken or on a drive belt which may have fallen off of a pulley? Can the problem be repaired? If so, with what and what is the best way in with the least probable damage to the building?
Thanks for your help.
