We had 2 big dust storms this week, so I figured that I better brush the 1" of dirt that sits at the bottom and run the pump for a couple of days. We had the pump motor running on filter for 3 or 4 days. Turned it off to change to backwash and then restart the motor. The motor did not start turning but rather it made a load humming noise. I thought something was in the pump section so I removed the motor. The pump was not full of garbage and I can easily turn the shaft of the motor. The motor makes the same sound when I run it with it removed from the pump. So, I am guessing the motor has partially failed.
My motor is a Century Centerion by A. O. Smith. It is about 7 years old.

Where can I get a new motor without paying the large mark up from the typical pool warehouses?
