How different?
I thought they were the same, but with different mounting locations. Mike |

Don't know the changeover dates but an "early" blower fan is a 2 outlet fan mounted on the fan housing about in the middle and the "late" fan is a 1 outlet fan mounted under the relay board.

The only 2 things I have found that goes bad with these old motors is the brushes, which I never found replacements for, it was easier to find a "new" (to me) motor than the brushes; and the "bearings" for the armature which would rust up or dry up.
