old condenser fan motor shaft was loose and it made the spinning fan blades shake and cause noise

The procedure was straightforward. I removed the cardboard backing on the lower back of the refrigerator to expose the fan unit. I then undid the electrical harness at the fan. I then removed the three screws securing the fan motor to the metal bracket. This is the hardest part in that I had to reach through and get to the screws with my small tools. I then removed the old motor and blades and placed the new motor and blades. Again, a bit tricky trying to get the three screws mounted into the bracket...small tools and hands helps. After that I used the electrical harness supplied with the kit to plug into the new motor and I was done.
