I have a Kenmore refrigerator side by side door dispenser that has a lock/water/crush/cube/light, display on it. The lock button has been turning on by itself without anyone setting it. When you unlock it to return it to the water setting and push the water outside lever it sometimes sticks as to let the water come out continuously. I had to actually put my finger on the water tube to stop it. I took the cover off to see that it has a chip board on the back and was wondering if replacing it would fix the problem? The part is 100.00 so I really need to get some good advice. 09/08/09
