REFRIGERATOR LEAKING WATER INSIDE THERE IS NO

Remove the food and remove the rear freezer panel . Using a hair dryer , start in the middle , below the coils , defrosting , until you
see the drain hole . Use hot water to help defrost the hole . Once water starts going thru the hole , use a small hose inserted into the hole , and blow thru , to remove any unseen debris in the drain line . Use an ALUMINUM solid wire , 14-16 guage , with the insulation completely off , and insert one end into the drain hole as far as possible without any force . Wrap the other end about 1 1/2 to 2 turns , around the black rod (defrost heater) , above the hole . When refrig goes into defrost , the heat will transfer from the heater , to the wire , keeping the hole from freezing up again .

The defrost drain has frozen with ice. You will have to remove all the ice and clear the drain. Be careful of the styrofoam ducts. make sure it is draining prperly and return it to normal operation.
