Can the defrost timer be adjusted on this refrigator?
Answer Hello Tom. No, you can not adjust the timer on the unit. If the timer is not working properly, you will need to order and replace the timer R0168027 on the unit.
The freezer is freezing, coils are freezing up and the unit is not cooling in the refrigerator section. What part do I need?
Answer Linda, based on the information you have given it sounds as if you have a defrost failure. The defrost system consists of the defrost timer R0168027, defrost heater R0130430, and the defrost thermostat R0130427. You will need to test and replace the defective part. You can test parts by using a MultiMeter TJMA-DM1. Here is a link from our free repair forum you can refer to for help with using a multi meter.
