Rather than waiting for the motor to fail I decided do the repair on my terms. The repair video was very helpful although on my model, SDR26VL, there is no need to remove the shelf brackets or the ice bucket. Additionally, the video identifies wires by color and position. Since the motor runs on AC no polarity is required. My model had different colors and no ground.
The new motor was not exactly the same as the old one. First, the new motor had male electrical fittings so I needed to attach female fittings to the refrigerator wires. I also needed to create a ground connection as the old motor did not have one.
The motors use rubber spacers as a compression fitting between the two metal brackets on this model. When I first installed the motor (first time) I did not notice the difference in the motors. The next day I noticed no air flow. The fan had stopped turning because a rubber spacer had started to brush against the motor shaft. This was easily adjusted and the motor runs fine.
Advice: Check that the rubber spacer on the fan side of the motor does not go past the armature housing. If the motor had stalled while I was not present it may have burned out.
Overall I was happy with the repair. It took me far longer than it should (2 hours) have but it is done and working.....quietly! If I had to do the exact repair again it would be less than 1 hour (with food removal)
