I determined the pump was not working by running the ice maker. After it started a cycle, I could fell the underside of the cold plate to insure it was indeed cold, but no water was flowing.
First, be sure the water pump electrical plug is in., it releases by pressing together the tabs at the ends, not sides.
To replace the pump, turn off the water supply and cover the drain hole at the bottom of the ice bin so you don’t drop parts down it. The screw-plug at the bottom of the water tank or a quarter will do.
Remove the water tank below the pump by taking out the thumbscrews at both ends. You can then see the hose at the bottom of the pump. If it is off, that may be the problem.
To remove the pump, pull the fill hose to the left out of the slot and bend it behind the pump to get it out of the way. Unplug the electrical connector and the pump hose. There are three ¼” hex head screws, teo on the side wall, one in back. The middle one is the hardest to access. I used both a nut driver and a socket wrench with a 4” extension.
When installing the new pump, be sure to plug in the electrical connector, the discharge hose at the bottom and position the fill tube as you found it. Forget any of these and nothing works. Re-install the water tank, replace the drain plug and turn on the water supply, in that order.

Bought new wire, strung it end to end and fastened it at each end.

The thumbscrews that hold the cutter grid can only be removed by using a needle nose pliers , you cannot turn them by hand. The electrical connections for the grid and level sensor can be removed by pressing the front side of the connector while pulling down. Re-installing the cutter grid is in reverse to the removal, just follow the instructions. But be aware that all wiring remains outside the grid perimeter when reconnecting. One other thing: While you are at it, remove the lower outside panel to expose the evaporator coils which need to be vacuumed. Replacing these parts is tricky. I had to remove the door then loosely install the upper retainer bracket for the lower panel so I could slide the upper edge into that bracket before installing the lower screws. I used an ice pick to line up the holes while using a blade screwdriver to push the panel in its place to install the retaining screws. It took me about a half hour after I figured out what to do.

Technically, the repair did not require specialized knowledge. However, replacement of the motor required some effort. Because the motor is located at the bottom of the unit in an area with copper tubing & wiring hindering access it was physically difficult to remove and then replace the motor. A problem arose because the shaft on the replacement motor was larger than the original motor's. Thus the fan would not fit on the new motor. Luckily, I found a fan locally that fit the motor. It would be very helpful if a fan was included in the motor kit. The ref. is now running smoothly

didn't go well at first. Got it all hooked up relatively easily but it didn't work. Called customer service who suggested hooking pump up to other power source to be sure it worked. It still didn't work. After closer inspection a connection wasn't hooked up on pump. After connecting got it back in about 30 min. Working like a charm now.
