Water running in refrigerater from freezer - Whirlpool Refrigerators

This happens from a blocked drain in the freezer.when the machine goes into defrost a heater comes on in the freezer and melts the ice off of the evap coil.normally the water drains down through a hole under the evap. coil but yours is blocked with muck,ice and matbe some food particals but over the years slime forms in the drain.if you know how to put the machine into defrost do it or just unplug it,remove everything out of the freezer,remove the inner back wall of the freezer and with a hair dryer melt out all the ice,all the ice has to be melted off of the coil or anywhere you see it,now you have to clear the drain,i use a steamer to blast through the stuff in there to clean it but if you don't have a steamer you need something that will blow into the hole like a turkey baster or a shop vac,try vacing the stuff out and then put it on blow and try to blow the line out,if you try to snake something down there watch out the drain is plastic,also you can open the fridge door and in the middle of the seiling you can heat it up with the hair dryer to melt the ice in the drain and then blow through the line,when you think it's clear pour hot water into the hole,if it drains through then it's clear if not keep at it until you clear it.
