GFS185 (MN04) Caloric Refrigerator - Overview

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.

De-iced the refrigerator. Removed two screws from the thermostat panel on the upper refrigerator section. Tilted it down, removed two speed nuts holding the timer, unplugged the timer plug. Determined from the instruction sheet (easy to follow) what time delay function is used, based on wire colors, placed the jumper on the correct terminal on the new timer. Plugged it in, replaced the speed nuts and screws. The timer fit perfect, works just like it is supposed to, quick easy job.

1. Unplug refrigerator to remove power!
2. The timer is inside the control housing located at the top of the refrigerator compartment.
3. Remove two control knobs (the pull off).
4. Remove the front panel escutcheon. The panel is not held in place with screws, but can be gently pried off.
5. Remove two screws from the back that hold the housing in place.
6. Remove screws from the front that hold the housing in place.
7. Drop housing down (still attached by wires - do not detach). Timer is inside housing, located on right.
8. Follow the instructions provided to identify your particular wiring setup. You'll find the wiring diagram (on my model) at the bottom of the refrigerator, alongside the defrost catch pan, behind the airflow grille.
9. Remove connector from timer terminals (4).
10. Remove two screws/nuts that hold the timer in place.
11. Install replacement timer following included directions. Read and follow ALL instructions applicable to your particular model and wiring setup.
12. Reassemble by reversing the steps above.
13. Note: You may need to "jog" the replacement timer when you first plug the refrigerator back in, if the timer happens to be in a "defrost cycle" (the compressor won't start). This can be done by inserting a wide bladed screwdriver into the hole below the timer, aligning it with the timer shaft, and slightly turning the shaft CW. Don't force it, and don't turn it very far.
