Disc stack not rotating.

If the disk stack is not rotating then the gear teeth are not moving the stack.

Remove the motor. If you do not know how the motor comes out, hit the "go Back" button
and select the "How to remove the motor" option before continuing.

Check to ensure the coupling is securely attached to the gear by following these steps.
  • Turn off and unplug the unit and spin the fan with your finger. When doing this, ask if the prongs/teeth are alternating from the gear. (moving)

  • If the prongs are not alternating from the gear, push the coupling into the gear and retest it.

    If the prongs/teeth are still not alternating from the gear, the life of the gear has probably been used up. (insert gear link)

  • If the prongs/teeth seem to be functioning test to see if the motor could be malfunctioning by hitting the "Go Back" button and selecting " Test the motor to see if it is working." option.
