The defrost timer is located behind the light diffuser in the refrigerator part of the unit, in very old units it is located behind the toe plate in the front of the unit, if you are replacing it you have to have a lot more letters and numbers than what you supplied in this question.
It's under the refrigerator, behind the grill. Pull out the grill, to the right of the condenser coils, there'll be a pinkish knob. That's the timer. You'll need to unscrew the panel holding it to get it out.
Look for it at the bottom of the refrigerator, behind the grill. Pull off the grill and you should see a red knob on the right.

To GE model GSSxxxx models, there is no defrost timer. It uses the main control board to time it.
The defrost timer is located behind the light panel in the ceiling of the fridge compartment. There are two screws that hold it against the plastic plate it sits on and hold the timer wheel against a hole in that plate which lets you advance it with out having to remove it.

the timer
At the bottom of the refrigerator, in the front, behind the grill. It is retained by a 1/4" screw to a metal plate. The timer is behind the metal bracket or plate.
I found it myself in front on the bottom behind the grille.
the clicking you hear is more then likely just a noisy defrost timer..in some ge refrigerators the defrost timer is mounted close to the temp control.
More than likely its the defrost timer or the defrost heater. You can try and advance the timer which is usually located at the top of the refrigerator compartment. Its usually a small round circle with a slot in the middle. Take a slotted screwdriver and advance it till you hear it click then stop advancing it. This more than likely is defrost mode. It should kick on the defrost heater. Listen closely if you can hear the heater kicking on and sizzling the ice. If you do advance the timer to run after about 1/2 an hour and repeat the process until the ice is gone. If this works then the timer is defective and needs replaced. If this process doesn't work then the defrost heater is probably defective.
Remove shelves from refrigerator compartment. remove screw from bottom of the control panel and ease panel bottom forewards then carefully downwards. This will allow the overhead panel to slide back and clear front clips and drop down sufficiently to give access to defrost timer.
The defrost timer is usually found behind the front grill "toe kick" of the refrigerator. It may also be found behind a cover plate inside the refrigerator or freezer.This is a very common feature on modern freezers
