I ordered a new switch from APP and fixed my fridge.
However, the video posted for this repair on this site is not applicable to newer refrigerator models.
I have a 2015 GE GTE18IHCRSS and had to drop the control housing (#432 in the diagram) to attach the wire/plug assembly to the switch. Only had to remove the front screw with a 1/4" nut driver and that provided enough of a gap for me to plug in the switch.
So the correct method to replace the light switch in a newer model refrigerator is as follows:
1. Unplug the refrigerator's AC power cord from the wall socket
2. Remove the front screw from the control housing with a 1/4" nut driver or small socket wrench.
3. Using your fingers, needle point pliers, or screwdriver blade, remove the wire plug from the switch. Be careful not to put pressure on the housing since the rear screws are still tight.
If you want, you can loosen the two rear screws a couple of turns to allow more play in the housing gap. I have skinny fingers so I didn't need to do that. I did keep my free hand on the underside of the housing when doing this repair, which you should do as well.
4. Using a screwdriver, press on the right side of the switch (the retaining tab) from the top side of the housing to remove the switch. During this step you must hold the bottom of the housing as I noted above.
5. Snap in the new switch and connect the wire/plug assembly.
6. Plug in the AC power cord to the fridge and your light should work good as new again.
This entire process took me all of three minutes to complete, including coffee break.
