Frigidaire Front Loader Spin Problem

I have a Frigidaire front loading washing machine model LTF530FS0 that will do everything except the final "fast" spin. It washes the clothes, drains the water, and rotates the drum during the spin cycle, but will not initiate the "fast" spin.

The motor appears to be fine since it washes and moves. Could there be a switch of some sort that causes the "fast" spin that I need to replace?

Thanks.

Sounds like the problem is a bad speed control board (#4 on the [B]Tech sheet, but there is a small chance for the the motor to be bad as well.
