I know it's disappointing when the icemaker stops working. The icemaker in this model can stop working for a few reasons. Some are listed below:
The icemaker itself can fail
The water valve may not open
The optic boards can fail
The fill tube can freeze up
Freezer temperature not cold enough (should be 0 – 5 degrees)
The blinking led light can be flashing a code that will indicate the problem. If it flashes 2 times pauses and continues this while the door is open, it’s normal. Now disconnect power to the refrigerator. To check this icemaker, slide it out, so the front cover can be removed, to access some test terminals. There is a clip located on the back right corner of the icemaker that will need to be removed, to slide the icemaker out. There will be a screw at the bottom of the clip holding it. I’m sending a picture with instructions to remove this clip. With the clip removed, slide the icemaker out and remove the front cover. You will now see the test terminals, which are marked (see picture). Now remove the 3 screws holding the receiver board on the right side and disconnect the harness from the board. Place a jumper between the black and black/white wires (see picture). Now use a second jumper and place it between the L – V terminals on the module. Reconnect the power and with both jumpers in place, water should now flow to the icemaker (be prepared to catch water from the fill tube). If water does flow, the icemaker # 2198597 will need to be replaced. If no water flows but you can hear a humming noise, the water valve # 4389177 will need to be replaced. If nothing at all happens, some voltage checks will need to be made. I hope this will help you.
If you do not feel confident repairing this problem or doing any voltage checks yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
