Argar,
When you "open it up" is there a large or heavy build up of frost or ice on the back wall(evaporator cover) of the freezer compartment? It sounds like a defrost issue. You'll need to check the heater assembly

Part number: AP4527302
Part number: AP4527302

for a "closed" circuit. Check the defrost thermostat,

Part number: AP2150145
Part number: AP2150145


For a "closed" circuit below 40 dgrs,F. and an "open" circuit at room temperature. If all checks OK, and there are no loose wires or connections, then the issue would be in the control,

Part number: AP4300940
Part number: AP4300940


Here's some information that should help you out :
"Manual Defrost Activation Press and hold Freezer Temperature UP
(WARMER) Key while pressing the fresh food temperature DOWN (COLDER) key 5 times within 6 seconds. Deactivation Press and hold Freezer Temperature UP (WARMER) Key while pressing the fresh food temperature DOWN (COLDER) key 5 times within 6 seconds. Function Initiates a defrost cycle. All other functions are disabled including alarm(s) enabling."

Thanks and Good Luck,
