open it. look for a wire that has become disconnected from careless factory assembly

The bearings on the motor are dry and need oil. It's really not made to be oiled, but you may be able to take it apart and get some oil to the bearings if you want to mess with it.

I had a similar fan which
quit. I could sometimes get it to start
spinning by banging on it. Finally took
it apart. Lots of small screws, all
small phillips. As I suspected, the
"thrust bearing," which supports the rotating components, had become
"stiff." I thought that it would be a non-friction (ball bearing),
but it is only a bushing, with washers supporting the shaft. With the motor opened up, I greased the
bearing with petroleum jelly, and reassembled everything. It is spinning very quietly now. Final comment - this is probably more work
than the average fix-it person would want to take on, but it is doable. It took about two hours, start to finish. I could do it in less than one hour now that
I know how to do it.

It sounds like the electronic controls have put the fan into "breeze mode". The fan turns slowly then is supposed to surge back to high. Some people love this feature for some reason...
Disable breeze mode via your remote (its the button with the stacked ~'s).
A bad motor wouldn't rotate at all. The only other problem might be the motor's running capacitor. If you can start the fan in either direction (give it a hand spin in the opposite direction of rotation) you have a bad capacitor...and you can find a replacement anywhere (Radio Shack).

I have the same issue, i determined the oscillating motor has a bearing failure. I need to find a replacement motor.
