Re: 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

here are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually (but not always) the first to be noticed. Frost" and "Ice"
There is a difference between "frost" (a white, snow-like substance) and "ice" (usually clear and solid). When referring to what is seen during an inspection, please keep this distinction in mind as the possible causes for each are often very different. The Defrost System
Inspecting the (usually rear) wall of the freezer compartment for a frost build up is necessary. (In the case of many GE top freezer models, check the freezer's bottom panel.) If there is a frost coating on it, it is often a sign of excessive frosting beneath it. Sometimes however the evaporator cover panel will actually need to be removed (see the illustration below) before an excessive frost build will visible.
The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. This evaporator will periodically frost over and have to be defrosted by means of a heating system. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. There may be just enough air circulation to cool the freezer section but that will eventually stop too.
It could be the freezer is over-stocked and air cannot circulate but often it signals an excess of water vapour is getting into the freezer from overuse or a faulty or misaligned door seal or from unwise use of the freezer.
Frost build up in one part of a freezer could also mean a part of the insulation is failing.
Clearing the ice build up is a good start,the problem though is the drain pan under the coil in the freezer thats iced up is blocked so when the defrost heater comes on and melts the frost from that coil,it the water is collecting in the freezer and in many cases drips into the fresh food compartment,clearing the drain will resolve your leaking/ice build up issue.THE DEFROST HEATER IS GOOD melting the frost in the first place and hence forth that melted frost stays in the freezer and becomec ice.
If you remove the bottom drawer in the freezer you will be able to see the back of the freezer. You will notice a large build up of ice in the bottom of that panel. If this is the case, you will need to empty the freezer up to the icemaker bucket. There is a panel with several screw in it that you will have to remove. Once removed you will want to defrost as much of the ice as you can with a hair dryer. Once you get the ice down to the hole you will want to heat some water up in the microwave and pour it into the hole repeatedly until it clears the line and drains on its own. This will remove whatever bug of ice particle that blocked it. Put everything back together and you will no longer have this problem.
The flap door where ice is dispensed is warped letting warm air into the freezer causing the frost build up. You must replace the flapper - a $5 - $7 part but not too difficult to replace. I find the flapper last only about 2 years and frost problem reappears. Forget about a "weak heater".
During the defrost cycle heaters in the wall of the freezer are turned on to melt the frost build up. This melted frost "water" is supposed to run out a drain in the bottom of the freezer and collect in a pan under the refrigerator/freezer where it will eventually evaporate. If this drain is blocked it will cause a lot of water to collect in the bottom of the freezer and that water will eventually turn back into ice. I recommend defrosting the freezer manually, removing all the ice/water buildup in the bottom, and trying to unplug the drain line to the pan underneath. Also check the seal on the freezer door. If it's not sealing well it could be letting a lot of moisture enter the freezer which would lead to more frost buildup and more water during the defrost cycle.
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 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 can 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 your ice maker causing this are very, very slim...in 35 years in the industry ..I have never had an ice maker cause frost due to water spray...it will almost always result solid sheets of Ice..if it evers does cause a spray....which like I said is rare...lottery ticket type rare :-)
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
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..
