Water to Ice Maker overfills trays

Ice maker continues to make ice but water overflows from the tray and runs down the side of freezer. Notice the emitter and receiver are not functioning too after reading other posts

Hi Keith,

If the ice maker overflows, then the problem is a bad water inlet valve on the back of the refrigerator.
