Ice maker stopped making ice - Samsung RF263AERS (258 cu ft) Bottom Freezer French Door Refrigerator

Broken wires at the ice maker or the temperature sensor falling out can cause that problem. Check your digital temperature readout at the top of the refrigerator with the doors open. If it reads 88 88 and has a flashing digit, check the ice maker temperature sensor for a cut or broken wire. The temperature sensor and rubbery gadget holding it in place often fall out of place when the drooping wires snag on the ice scoop or whatever. The sensor assembly is held in place by a wimpy plastic clip that breaks easily. Sometimes the wires get cut or broken when this happens.

After fixing this problem several times, I finally made a metal bracket from aluminum angle, drilled and tapped 4-40 holes in it, and drilled the plastic icemaker to mount it more permanently. I added a wire tie to hold the temperature sensor wire up and away from possible snag sources. The sensor wire and wire tie are not shown in the photo below, but if you have the tools to solder the wires and fabricate a bracket it helps a lot. It is easy to get the ice maker out, once you discover how to remove the drawer from the slides (two plastic clips at the rear of the slides).
Pull the front cover off, take out the two screws, and unplug the wire connector and it drops right out.

Bracket installed. The sensor is not shown in this photo, but the wire comes out the right side and crosses in front of the metal bracket. The wire tie holds it to the bracket near the top center (hole not shown).
