THe ice /water dispensor is throwing out ice and water independent of contact from a glass hitting the dispense level, to have it dispence. As a result we have turned of the water and ice control but now the light now stays on or flickers. What can we do othre than get a service?

This is a general answer. The water dispenser paddle makes a switch that then opens a water solenoid valve that dispenses the water. The ice paddle makes a switch that starts an auger in the ice bin to push the ice out. There is either a rod across the bin to detect the height of the ice in the bin or a thermostat that hangs a little way down in the bin. These will open a water valve to fill the evaporator to make more ice if they think the bin is low. Mineral buildup in the water valves is fairly common and can keep them from completely closing. I don't know which light your referring to, but the low ice light should go off when the bin hills. Also, small inline water filters are available in most hardware store to filter water for refrigerator use. I hope this helps.

Make sure the water supply line is turned on (the valve probably is behind the fridge or under the sink ) also check if is kinked or damaged.
