Customer Questions and Answers for Defrost Timer by Ge

Frank, You will want to first check to make sure that the fan in the freezer is operational. If not then check to make sure that it is getting 120 vac. If it is then replace the fan. If the fan is working then check to make sure that the evaporator coils are not impacted with ice. If it is then it sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
