You can test the timer with the first cycling as you watch the timer on the arrow line. When it is done, you can subtract the current number to the arrow to get the amount of time in the cycle. There are many possible causes that can prevent the agitate from spinning. Some of the common causes are the fuse, small load in the cycle and overloaded dryer. You can consult the manufacturers for advice. See http://www.ehow.com/info_8452200_ge-washing-machine-wont-spin.html for reference.
