Looking for help with the Whirlpool GR2SHK-XKQ00, top mount refrigerator. Water is coming into the refrigerator from the freezer, possibly linked to self-defrost cycle, def. not ice maker. Drain pan is empty. Is there some kind of drain tube that might be broken or blocked? Where would it be located? Thanks!

Remove the lower freezer panel end then remove the rear panel . Remove the ice under bottom panel . Useing a hair dryer , heat the aluminum tray under the coils until you see the black drain hole . Continue defrosting the hole until free of ice . Could help useing a small screwdriver into hole . Even hot water into hole could help to clear . Once water will drain into hole , use a small hose inserted into hole and blow thru it to clear and obstruction in the line (line is inside the cabinet , unaccessable ) , Then find about a 14-16 gauge aluminum wire , aluminum fence post tie , aluminum ground wire , and insert it into the hole until resistence is felt . Wrap the top portion about 1 turn around the calrod (black) heating element and cut off the rest of the aluminum wire . The element will transfer heat to the wire during defrost , to keep the drain hole clear of ice .
