GE washer model GLWN2800D0WS works fine but now final spin cycle takes over an hour. Don't know if timer or motor control is the problem.

Possible your outlet filter is blocked. This requires cleaning depending on your usage. Clean this out and refit. Good luck. Plug off the wall first.

This is an interesting problem. How long does it have to sit before you can get it to spin? Can you let it go through the cycle and then immediatly put it into spin and it work? This machine will not spin until the pressure switch senses the water has drained. So you could have a slow drain, a clogged pressure hose, or faulty switch. A clogged hose or faulty switch would usually cause it to fill with more water than normal also. A slow drain is most likely, check the drain hose when it is draining and see if it is putting out a strong flow or just slowly draining. I think you will find it to be slow. This will cause it to take up all or most of the spin time trying to drain the water. If it is slow draining, check the pump for a sock or some obstruction. If the drain is good, remove the top and remove the rubber hose from the pressure hose and blow through it. You should be able to blow through it easily. A restricted pressure hose will cause the machine to think it has water in it after it has drained.
