So the freezer is freezing but the inside floor is melting? I'll just throw this out there... I'm wondering if the compressor is over heating because everything behind the bottom grill is plugged with dust. Try pulling the grill off and very carefully vacuuming everthing. The aluminum fins are fragile and bend easily so use the vacuum brush on this. The vacuuming should be done frequently depending on how dusty your house is. TURN OFF THE POWER SO THE FAN DOESN'T GET HIT.

Most likely the ice door is not closing properly.
Clean out the ice chute and look down it from the inside while you shine a flashlite up from the outside. If you see light around the door then it needs to be replaced or something is wrong with the mechanism.
Post back and let me know what you find.

SOURCE: Excessive Frost and Ice Build up in Freezer

sounds like you have a clogged defrost drain tube. removing back panel of freezer will give you acess to drain trough, melt away the ice with a hair dryer, youll find a drain hole under there somwhere,pouring boiling water down the drain will clear it pretty quickly( i use a steam machine purchased from the infomercials works awesome, after you clear it and all water drain down tube wrap a piece of solid copper wirearound the heater( black calrod heater right above the drain trough) and stick it in the whole maybe an inch or so. now everythime the heater comes on to defrost it will prevent the hole from freezing over

SOURCE: Ice build up in my frost free upright freezer

I looked at the BACK at the bottom underneath of my Sears Kenmore frost free upright freezer and what was causing the ice buildup was very simple. At the factory, the assembler looped the little hose too high and when the water went into the hose it could not get out due to being too high in one spot! An ice dam will form, blocking ALL water coming through
and freezing up any more water coming down giving you a HUGE wad of ice that is scary!!! I just removed the screw holding the loop that holds the hose and put a bit of warm water down the little hole on the INSIDE (Behind the grate) to melt the remaining ice in the tube.You need to take out 4 screws and remove the grate to see this. I could not believe that this was the problem! I haven't had any ice build up since.Now don't tear your freezer apart before you try this trying to fix the compressor, thermostat etc. It may be the only thing wrong with it!

SOURCE: Kenmore Trio bottom freezer frost free. Producing frost

There are several reasons this can be happening...

1. The seal on the door may have a tear or may not be seating properly...this allows excess warm air into the freezer compartment and in its effort to remove the same ...frost appears.

2. There is something call a thermistor (which senses temp and ice build up) that is cycled on and off as needed to remove excess frost accumulation and or ice buildup on the evaporator (freezer) coils...it is a heat strip which actually defrost the frost/ice. If this is not working frost will accumulate and eventually it will become Ice......now the remarkable thing about Ice accumulation is that you would think everything would remain cold or get colder ..however in this case the opposite occurs...it insulates the coils and thereby increasing the temperature...put a thermometer...one that is calibrated properly...(calibration can be set by placing a thermometer into a glass of ice water...the temp of a glass of ice water..after a few minutes setting will be exactly 32 degrees)..if the temperature of your refrigerator is gradually rising over the period of a week...you will need to call a tech or replace the thermistor and or trouble shoot other problems that may have occur such as..

3. The evaporator fan may be going out although they usually make a high pitched whining noise of a whirring noise before they go out...not always and if they are intermittently cycling off then frost would build up...do you always here a fan running when you open the freezer...if so that is good...fan is working...but it may be cycling off at times when no one is aware.
P.S. the odds of it being due to overfilling are slim...I have been in the industry for 35 years and that is what freezers do...which a lot of people don't realize is that freezers don't actually cool anything ..they just remove heat and when you remove all the heat all that is left is cold (like in space) and when heat is removed quickly frost can appear like when you blow your breath on a freezing cold window..then right your name....but I digress...any way..if there was an excess of heat due to a lot of new food in the freezer it would correct itself by one of the processes i mentioned above..and it would never result in Ice..you probably have one or more of the problems I mentioned...evaluate how long its been going on...

4. Thermostat could be out of adjustment..and or not functioning
properly..which would delay or inhibit a defrost cycle..from occurring..unfortunately almost all of these problems require a tech...or a good handyman.

This should lead you in the right direction...if you need help in finding a reputable service company in your area let us know..I hope this has been helpful..if so PLEASE rate me....thank you... .......The Fang

SOURCE: frost free freezer with ice in the bottom and

Frost Free Freezer have an automatic defrost, which is essentially a heating element which melts any ice. If your door seals are in poor condition or something is preventing the door from sealing the ambient air may be melting the ice more than the drain can accommodate. Check the drain in the bottom of the freezer. Humidity can also cause more water to accumulate, especially if the door seals are not sealing.

Icing up


I've just had a similar problem. I fixed it by removing the large panel on the back of the inside of the freezer. I found a large build up of ice at the bottom of the freezer which seems to have developed because the drain hole at the bottom of the freezer was blocked. I defrosted the ice, cleared the drain and now the freezer is working fine.

LG Bottom Freezer Frost Issue


It sounds like your defrost controller has gone bad. I have an LFC25760 and had ice build up in the bottom of the freezer such that water would start leaking onto the floor. The ice build up in the bottom of the freezer was due to a failing/bad defrost controller. Behind the back white wall in the freezer compartment exists the cooling fins along with a heating element underneath. Due to moisture that comes into the freezer from opening it, frost/ice builds up on the cooling fins. Thus the defrost controller turns on the heating element to melt the ice/frost off of the fins which then drips into a metal pan which channels the water to a drain hole which drops into the drip pan underneath the fridge next to the fan. The problem is that the defrost controller doesn't keep the heating element on long enough or the cooling cycle comes on too soon thereby freezing the water and plugging up the drain. I had my defrost controller replaced (just outside the warranty period!) and it worked for about 1-month and then same thing happened again. Instead of paying for another defrost controller that would probably not work 100% my serviceman used the old paper-clip trick. He took a paper clip, stretched it out and then wrapped one end around the heating element and placed the other end into the drain hole. Thus when the heating element comes on the paper clip keeps the drain hole warm/hot and prevents the water from freezing. It has been 9 months since this fix and I haven't had any ice pooling in bottom of the freezer.

Frosting & water dripping from freezer in Frost free freezer


Hi, You will find that your problem relates to the defrost heater in the freezer. You will need to take the drawers out and remove the back panel to access the evaporator. There is a foil heater that lays underneath the evaporator and it will need to be changed. Along with the klixon that controls it. This will ensure that both parts are good. Your problem will then be fixed no more water!
Good luck................

Viking freezer frost build-up


Sounds like a defrost problem. Check to see if there is any frost buildup in the back wall of the freezer. If so, it is not defrosting as it should.
  • possible causes:
  1. bad defrost timer/control board
  2. bad defrost heater (in freezer)
  3. bad thermo switch in freezer
If you don’t know what these are then unplug the machine and let the ice melt in the freezer overnight with the door open. Then try it the next day, if is cooling fine then you need to have a service person replace one of the above items.
  • if you already checked this and think it is a different problem then let me know, i will help you figure it out.

If the ice build up is only on the back panel of the freezer then you have a defrost problem. Most likely a defrost thermostat or control board/timer. If frost build up is around the walls of the freezer then warm air is getting into the freezer. Most likely cause of this would be gaps in or torn door gasket or door alignment. In some cases the door was left cracked open. If gasket and door alignment is ok remove the frost and see if it comes back.
