Upright freezer,automatic defrost.

You have a plugged defrost drain line.Lokk on the very bottom and way way back to see if yu can see the drain. Also check underneath you lmay be able to get to it from there or else in back of freezer.Hope this helped.

It sounds like unit is not properly going into defrost or your evaporator fan motor is starting to go bad

get down on the floor and look along the bottom of the door to make sure that the door seals are touching.if not and you have an air leak it will cause frost.if its ice and not frost then check all vents/drains are clear.

If it's a frost free model, it could be caused by a plugged defrost drain. Every time it goes through a defrost cycle the water is supposed to drain into the compressor compartment. You can defrost it by unplugging it for a day or two and then remove the panel covering the evaporator coil. You should be able to see the drain tray under the coil and find out whats blocking it.

Either the drain hose is plugged up with ice and not dripping into evaporator tray, or the defrost unit needs to be replaced.

Either your defrost timer, defrost heater or defrost thermostat has failed. All parts are located behind the lower back panel inside the freezer. Most likely are the defrost heater and defrost thermostat.

defrost drain may be plugged.shut freezer off,melt ice with blowdryer,and unplug drain.drain probably located behind inner back wall beneath coils.

There is normally a small filiament of metal which is attached to the defrost element and conducts heat down the drainpipe preventing ice build up. You can pour some boiling water onto this area and even wriggle a piece of plastic tubing down the drain pipe to dislodge any blockage. For future prevention, you can attach a piece of copper wire around the defrost element (in the absence of the original filiament) and extend it down the drainpiple

Defected DEFROST HEATER can cause frost build up on the panel at the back of the freezer,and freezer stop cooling and ice frozen on unit so air could not flow to refrigerator side.Water will coming out caused of unbalanced freezing,and causing the flooding of water in the floor. You must change this defroster heater assembly so it will works normal again..


Hope this may help;
