Yes, the fan is working. I am going to start changing parts that are related
to the problem, starting with the Defrost timer. Anyone know where I can
locate this? I have searched the fridge with no luck. Thanks in advance.

I have purchased the new timer, I can't find anything that resembles it in
the fridge, unless they gave me the wrong one. My fridge model # is
GSS201EMA and it is GE.
