    thanx ill try toi check out the links,in the mean time..this is a newer non freon unit, it doesnt seem to be getting cold enough to cycle off and this lower coil in the freezer is freezin up- in the ol days it would be low on freon and need a charge,firts fella said it was dehumidifier- what the - a fridge is a dehumidifyer. im ready 4some hep- thanx in advance

If only part of your coil is frozen it sounds as though you may have lost some of the charge or your compressor has lost its efficiency with age. You said the condenser fan is running, is the condenser clean? Give it several hours to run before you condemn it. You have nothing to lose by waiting. Defrost timers usually cycle on compressor run time not just on a schedule as such.

After looking through the old solutions and the process you have done , there is nothing much more left that we can solve the issue. The only thing is to Buy a new one. anyway as this is 10 years old i think it would be better if you go for a new one. If defrost is done properly then it may work, but even u said that u already changed the defrost thermostat. so that is not the problem, anyway i suggest is go for a new one. Even if u solve it, it will work temporarily and after few months it will again get some more problems, so it is also a waste of money and time , so better to go for a new one.Plz rate my answer

There R 2 things that need 2 be known for refrigeration.
1. A gas cools on expansion.
2. When u have two things that r different temperatures that touch or r near each other, the hotter surface cools n the colder surface warms up. This is a law of physics cald the Second Law of Thermodynamics.

Old Refrigerators
If u look at the back or bottom of an older refrigerator, you'll see a long thin tube that loops back and forth. This tube is connected to a pump, which is powered by an electric motor.
Inside the tube is Freon, a type of gas. Freon is the brand name of the gas. This gas, chemically is called CFC. This gas was found to hurt the environment if it leaks from refrigerators. So now, other chemicals r used in a slightly different process (see next section below).
CFC starts out as a liquid. The pump pushes the CFC through a lot of coils in the freezer area. There the chemical turns to a vapor. When it does, it soaks up some of the heat that may be in the freezer compartment. As it does this, the coils get colder and the freezer begins to get colder.
In the regular part of ur refrigerator, there r fewer coils n a larger space. So, less heat is soaked up by the coils n the CFC vapor.
The pump then sucks the CFC as a vapor and forces it through thinner pipes which r on the outside of the refrigerator. By compressing it, the CFC turns back into a liquid and heat is given off and is absorbed by the air around it. That's why it might be a little warmer behind or under ur refrigerator
Once the CFC passes through the outside coils, the liquid is ready to go back through the freezer and refrigerator over and over
How Does the Temperature Stay the Same Inside?

A device called a thermocouple (basically a thermometer) can sense when the temperature in the refrigerator is as cold as you want it to be. When it reaches that temperature, the device shuts off the electricity to the compressor.
But the refrigerator is not completely sealed. There are places, like around the doors and where the pipes go through, that can leak a little bit.
So when the cold from inside the refrigerator starts to leak out and the heat leaks in, the thermocouple turns the compressor back on to cool the refrigerator off again.
That's why you'll hear your refrigerator compressor motor coming on, running for a little while and then turning itself off.
Today's refrigerators r very energy efficient. Ones sold today use about one-tenth the amount of electricity of ones that were built 10 years ago. So, if you have an old, it's better 2 buy a new 1 cz you'll save money (and energy) over a long period of time.
belo are few links that shall help u understand system betta..so dat u can fix it ur own

GE ice maker


If the freezer is cold enough to freeze food hard, look for a problem in the water line, water inlet solenoid valve, or possible ice build up on the ice maker itself that does not the allow the ice maker to complete it eject cycle and start a new ice making cycle.

GR-349SQF won't freeze


Hello,

Compressor is one reason why your freezer may not get cold. The compressor which is usually found at the back of the freezer helps to pump out gas/ cold air and the fan circulates this cold air in the freezer. If this compressor is knocked/defective, the freezer won't cool. Also, gas in the compressor sometimes get's finished and needs to be refilled. So, the compressor needs to be checked in a situation like this.

Fan problem is one of the most common reasons for the freezer to start failing, this is called "frost free failure." Ice can build up on the evaporator coils over time, and this ice builds up until it starts blocking the fan. The fan is responsible for circulating cold air throughout the freezer, so if it is blocked the freezer will not be able to freeze any food. You can usually check this by removing an access panel in the back of the freezer to inspect the coils. If ice is built up on the coils, a hairdryer can assist in defrosting them.

It's also possible that the fan is not running at all. If the fan is burned out or the motor isn't running, cold air can't circulate through the freezer and everything will melt. You can normally hear the fan motor switch on and off from time to time. Listen for it and if you can't hear it coming on for an extended period of time, the motor may need repair or replacement. The wires connecting to the fan may be the problem, preventing the fan from receiving electricity.

Several other problems could be keeping your freezer from freezing:

There could be leaks in one or several of the hoses in the refrigerator, which results in the cold air being lost instead of circulating properly throughout the fridge and freezer.

If you have the freezer so full that the cold air can't circulate, your food will thaw even though the freezer isn't malfunctioning. Always leave some space open in the freezer and try to not store food right up against the cooling vents.

The thermostat might have shorted out, which means the freezer can't accurately determine how cold it is. If this is the case, the refrigerator would probably not be working, either.

If your defrost drain becomes clogged, the water in the line will just refreeze over and over again, which could damage the lines as well as the fan. Always check the drain and make sure no sludge is building up in it if you have a self-defrosting refrigerator.

Always try to keep the freezer door closed for long periods of time. The more the door is opened, the more warm air is let in and cold air is released. If the door is opened frequently, the freezer could be warming faster.

I hope the above helps.....

For further assistance, please let me know.

Can this refrigerator be used in an unheated garage?


Yes, You can use most any refrigerator in an unheated area. Just be aware that if it is in a below freezing area for a long period of time that the cold may penetrate enough to get the refrigerator temperatures below freezing also.

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
  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.

Jenn Air ref/freezer not freezing/cooling


Take the back out of the freezer and check and see if the refrigerator is in defrost while it is cooling if it is replace the timmer, then check and see if the fan on the underside is working if not replace the motor this will cause the problem also.
If all that is ok feel the small line under the refrigerator ( high side) and see if it is hot while it is running if not check the freon in the refrigerator.
