The frost free feature of the freezer was freezing over with ice and cooling coils were being insulated with thickening frost which caused the cooling air to rise in temperature from -5 degrees to 20 degrees.
I troubleshot the problem by reading the electrical schematic and concluding the heating elements (defrost cables) were either defective or the bi-metal temp sensor was open. When closed the temp sensor completes the circuit for the current to flow through the heaters to defrost the cooling coils every 8 hours and then when the bimetal opens at 55 degrees the circuit is open and the coils are cooled because the refridgeration motor is in run mode. A timer between the motor and heater elements also was defective. The timer controls the cooling period and the defrost period. I ohmed out each part according to the spec sheet of normal resistance of parts and thus the bimetal and timer were defective. I gather a surge of some duration and amplitude affected these parts because a storm 24 hours prior to refridgerator problem had passsed through the area and the AC electrical power had oscillated several times during that event. I used hand tools to do the repair. If you are not mechanically inclined a step by step proceedure would be moot. It is a matter of disassembly and assembly paying close attention to fragile parts.

Lights inside refrigerator not working
I used a flat-head screwdriver to pop out the old light rocker switch. Then, I unplugged the wires, plugged them into the new light rocker switch, and then popped the new switch into the hole. That's it! Lights began working again.

Defrost timer was faulty. Required a mild tap to restart
Trouble shot the electrical circuit per the electrical schematic and zeroed in when I noted the Defrost Timer circuit was open. When I tapped on the bottom of the timer it began functioning normally (for a few days). Ordered a new Defrost Timer Kit and along with the installation instruction, I watched the on-line video. It was very helpful!!
After installation was complete, I plugged the Refrigerator into the electrical outlet and.......nothing happened! Hmmm!

Removed the Defrost Time Kit and inspected it for any damage and found none. Then I placed a flathead screwdriver to the manual advance knob and slightly rotate the gear mechanism. I heard a distance "click”. I believe the Timer was in the ‘defrost’ mode when received.

I reinstalled the timer, verified the wiring connections and this time plugged the Refrigerator into the electrical outlet and ….. it worked!!!

I unplugged the refrigerator, finished the installation per the instructions, plugged the unit in and monitored it for a few hours (just in case). That was a week ago and the Refrigerator is working like new.

The instructions were written in a manner which required re-reading a few times as they could be a bit vague. The video was what really helped and I appreciate PartSelect adding it to the instructions.
