First find out what the noise is.
What is running and what is not.
If the condenser/compressor fan is running then the compressor should be running.
I think but cannot confirm this as I do not have a wiring diagram.
The second link above has good info on how to check the compressor overheat and start relay.

Following are a couple good links on basic fridge repair.

Look under the unit in the machine comartment and behind the kick plate for the wiring diagram.
It is a GE so getting any tech info off the net on it is very difficult. GE likes to keep everything a secret.
