Electronic Control Boards - Emitter and Receiver

I installed the 2 circuit boards. Real easy. Did not fix problem so going to have to check further.

I changed new valve & new electronic control board but still not working. I think the only one think left is Icemaker control and motor assembly

After checking the codes, they indicated that the emmitter board was inoperative so I changed the control boards. Very simple and straight forward (about 10 minutes). After changing the boards I double checked the codes, this time the codes indicated the control boards were functioning properly but still no ice. A friend suggested the water feed line could be frozen and defrosting the freezer could possibly resolve the problem. My freezer is full and it will take time to empty it to continue. Any other suggestions in the meantime? Installing the new water filter took about a minute and is working properly.

Replaced sensors but still not making ice. Followed the Brown wire from the Water fill selenoid to the Ice Maker Module. Take the three screws off the Icemaker Gearbox and there was a severely Crusty Connection. It cleaned fairly well and Presto.....ICE!!!

Unplugged appliance, removed both boards, 3 Phillips head screws in each, reinstalled new ones. Shortly after ice was coming.

Removed the three screws on the right or the bigger control board, then there are two screws that hold the control board on the cover took them out, unpluged the board, plugged the new one in, put the two screws back in the control board, put the three screws back on the cover. Left side or receiver, took three screws out, two screws on the board, unplug board, plug new one in, put two screws back in board, put three screws back in cover. BUT IT DIDN'T WORK STILL NO ICE. Led light said it should be working now . Need answer to my problem?

I installed a new icemaker and ice level sensors I also had to replace crummy plastic trim parts because of poor quality and broke during disassembly

After researching the problem on parts select I found that there were several reasons why the ice maker would stop working. The number one reason was the electronic sensors fail,these tell the ice maker when ice bucket is filled. The light on the electronic eye will blink a code to diagnose the if there is a problem with the sensor. In my case the sensor was bad(the red sensor light would not stay on). The light transmitter is on the right and the reciever is on the left. First make sure there is nothing blocking the holes by cleaning them with a "q" tip. If they still don't work and the blinking code indicates failure them they need to be replaced.The sensors are behind panels on the left and right; each panel had 3 screws that need to be removed. First shut off power to the frig. Once you remove the screws you will find a quick connect attached to a electronic board on each side. Unplug each board and replace with the new part. Replace the panels and turn on the frig to test. The instructions in the parts box will tell you the light codes that will indicate that the boards are working. One note, I did this repair , the sensors were working and I did not get ice after 30-60 minutes.I found out that the water fill tube(black tube at the top of icemaker) was clogged with frozen water thus the ice tray never filled. After clearing out the ice with a small pipe cleaner the ice maker tray fill with water and the ice maker made ice on schedule.
