I have a GE PSC23SGRB refrigerator and the ice and water have stopped dispensing. I replaced the display board that has the ice/water buttons on it but that did not fix the issue. I press in the lever (the one that the cups hit) at the back of the dispensing wall and the lights turn off on the display board. Any ideas?

Have you checked the water supply and the filter? Make sure you have water because with both failing it's something common to both. I will try to find something on this model and get back to you. DrTom4444
