Freezer runs constantly and ices up

Ice is made when freezer temperature is cold. Freezer and refrigirator will not cool if iced up on back wall. Your defrost system failed, causing frost buildup on the coils and restricting airflow and heat transfer. Most likely cause is a defective defrost timer that is not advancing into defrost (2-3 times every 24 hours). Defrost system comprise Timer, Heater, and Thermostat. You need the tools to diagnose the cause or just try one by one to replace the parts. Other choice is to call a tech. The freezer must be defrosted one time manually to remove the long accumulated frost.

It usually means that your door is either not closing properly or the seal is deformed. Moist air is getting in and condenses on the coldest surface at the back of the freezer. Check that the freezer is not too full (stopping door from closing fully) and check the door-seal.

Sometimes it is caused by icing of the thermostat. Ice is a good thermal insulator so the thermostat does not switch and the freezer keeps running constantly. Make sure there is adequate air circulation and no ice around the thermostat.

Defrosting usually fixes either problem.

Reduce thermostat setting point by point till no ice accumulation on fan.

the defrost has melted the ice,now the drain tray is plugged and needs a wire run down from the drain in the freezer to the condenser pan so it can evaporate,as this fools the temp thermostat trying to cool the refrige compartment to keep trying to cool the unitif theres water dripping into the fridge rom the freezer this is a good indicator of this problem

Are you sure it's the ice maker that's leaking? We have this model & ours accumulates a HUGE iceberg in the bottom of the freezer, but the water seems to be coming out of the back, at the bottom of the back panel, where the vents are.

If the frost builds up on the evaporator coil, sounds like the defrost heater may be out. Check continuity.
If the frost buildup anywhere else - there must be an air leak somwhere. Usually it's the gasket or the ice dispenser flap stuck open.

Good luck!

Are you certain that the ice build-up is actually originating from the water flow into the icemaker? If ice is built-up on the rear freezer panel, then your problem is more than likely a defrost component issue (defrost thermostat or defrost heater(s). If the ice is built-up on the side wall of the freezer near the icemaker, then water is probably being diverted inside the water inlet tubing that goes into the icemaker. This diversion is usually caused by an accumulation of ice inside the water inlet tubing. You will probably need to remove the icemaker in order to glance inside the water inlet tubing to see if ice is in fact inside the tubing. If so, take a screw driver or other object that won't puncture the tubing and remove the ice.

Contact an appliance service company if the ice is on the rear freezer panel.

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

The timer that controls the defrost cycle/function, may have failed and there may be no defrosting occurring. If icing of the coils due to the missing defrost cycle, there may not be enugh circulation left to keep the thermostat happy.

Try defrosting it manually (I know, it's a pain - aren't we spoiled?) and see if the compressor then cycles for a few days before it starts running continuously again.

And for Dr. Fred, the above suggestion about trying manually defrosting applies to your problem too.
The exposure to overnight moisture (ice accumulation) may have interfered with the automatic cycle.

If the frost build up is on the back panel of the freezer then it has a defrost problem which causes a no cool situation. Let me know more about this frost buildup and what you have done.
