Question

After having the refridgerator unplugged for a couple hours, the ice maker is not dumping ice. There are ice cubes made, ready to dump. I tried raising and lowering the lever in the ice maker. I also checked the water supply...I am able to fill a glass of water from the water dispensor.Ice maker will not dump ice but makes it fine!
