Determining the age of my GE BMY

[Cam Kuruliak]

I have a 12 inch GE BMY fan Serial # 887922 It has the CSS in it along with a pull out knob that locks the trunnion when you can use it as a wall mount I did some research and I believe these were made one year in 1915? It growls when you start it up but runs smooth  I have another question When I turn it on to the first speed it is the "high" speed and goes down from there. In fact on position "3" it turns off so I do have a speed coil issue  for sure Seems the wiring was untouched to me. Any help much appreciated I hooked up a temporary power cord to show what is happening

Thanks for your input

I want to say 1908-1909. But I’m not sure

Does it have flat front mount struts or angled side mount struts?  I think 08 is flat and 09 is angled.

Hi Cam,

That Serial Number would more correspond to 1911 or 12, any possibility you misread the S/N?  I've got a BMY S/N 388038 with the pull knob on the base, any chance the 8s in your S/N are 3s?

08-09 centrifugal start models don't have a base trunnion pivot. An early 1910 centrifugal start would. In the GE 1911 fan motor bulletin it was announced the centrifugal start mechanism had been discontinued

Late 09 or dirt early 10 centrifugal start variant.  Notice the trunnion can only swivel side to side.
