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.

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.
