First check your warranty and see if any of the components, particularly the electrical boards are still in warranty. Then contact Frigidaire and see if they will provide any warranty service since you are just out of warranty. Not likely, but worth a try.

You then need to see if you can put the machine in test mode and retrieve error codes which will help diagnose your problem.

Here is the service manual which will show you how. A bad wire between the speed control board and main control can be the problem, along with problems in the speed or main boards.
