1. Check plug that goes into wall and see if something has come loose or maybe a wire broken
2. Do the same at the motor itself. If you have the cover off for the red reset button you are 2 screws away from checking this. (Make sure it is unplugged)
3. 2 screws on back of switchbox to check for connections in switchbox. (Make sure it is unplugged)
Check the above website and put your zip code in and it will tell you where your closest Baldor shop is located. They can test your motor.
5. If it proves to be your motor I'm happy to get one to you
