My 13 yo Kenmore refrig has icemaker that has a bad fill valve per repairman. Did not want to spend $275 to replace valve. Now 3 weeks later water is dripping fast out of fill try and flooded my refrig. And onto floor. How do I stop the water from flowing from it? I The arm is in 'off' position and has been for 3 weeks. I pulled refrig. Out and turned the 'pin' valve on water line to right all the way until it wouldn't turn more. Still water is dripping fast out of fill tray. It is now 5 a.m. Mon. and am still mopping up water, PLEASE help me find out how to stop water from flowing.
