Customer Questions and Answers for Refrigerator Temperature Sensor by Ge

Roger,

You will want to check the temperature sensors resistance to make sure that they are good. The Sensor resistance should be as follows: 42.2K ohms @ 0 degrees, 14.4K ohms at 37 degrees and 5K ohms @ 77 degrees. If the thermistors check ok then you will want to make sure that the unit is defrosting by checking the evaporator coils in the rear of the freezer compartment. If it is approximately every 8 to 12 hours that the unit shuts down then it may be sticking in the defrost cycle in which you would need a new control board.
