Review on Enhance Your Bathroom's Ventilation with NuTone S1200A000 Bathroom Motor Assembly by Justin Rasmussen

It was used as a replacement for the motor in the Ventrola A109C-2 ventilation unit. It worked, but it took some effort. This part is not identical, but I could not find an identical one. Differences: (1) The motor shaft is longer and can cause it to catch on top of the ventrola breather assembly. I folded back some of the pieces to fit my old fan. (2) the fan is too big for the 6 inch chassis in the ventrola assembly. I pulled a 5 blade fan off the shaft (difficult) and put it on the shaft of this part. The landing of the old 3-blade fan on the shaft went well. (3) The mounting stud threads were slightly smaller than stock, so I had to replace the mounting nuts with those I found in my miscellaneous parts bin at the garage. The distance between the mounting bolts was the same as the original engine. Once I swapped out the motor and turned it on it ran fine, but it was a slightly frustrating process involving opening a roof vent to get the top vent tube back onto the assembly after the new motor was installed.
