Can you tell me why please?

As the freezer is working you can probably discount that the reason is low refrigerant gas. The other reasons would be that the fridge circulation fan has failed.
or
The channel that directs cold air from the freezer is blocked with ice at the rear of the freezer. It happened to my GE and was caused by a failed defrost timer that was icing up the evaporator coils at the back of the freezer.

A service call lasts about an hour including melting the ice with a heat gun..

Brenda, try the following.

1. disconnect power from the wall.
2. open fridge and freezer doors and leave them open for at least 5-6 hours. salvage foods you can.
3. after a few hours you will see a puddle of water under the fridge.
4. clean the floor and the fridge and freezer of any collected water.
5. power up the fridge and set at recommended level say 4.
6. you will hear humming noise. Let the fridge and freezer cool.
7. dont overload food.
good luck

ok,when you open the freezer door do you hear the fan blowing?all that happens is the freezer gets cold,a fan in the back wall of the freezer turns on and blows cold air up into the fridge section,a thermostat tells it when it's cold enough or it's getting warm then it will blow more air up top,if the freezer is working correctly then either the fan isn't working or the bottom freezer door was left open,warm air got sucked up into the air vents causing water droplets to be formed,then they freeze blocking the air vents with ice and now the cold air can't go into the fridge section.is there any ice on the ceiling of the freezer or frozen water droplets on the bags in the freezer?if so the door was left open.unplug the maction,and with a hair dryer blow the hot air into the holes on the back panel,keep doing this until you don't see any more water draining through the holes,turn it back on and see if the cold air is blowing up into the fridge.if the evap fan motor is bad the part number is W10128551 and it's around 25 to 30 dollars.you must of got the model number off of the book,it's not the full model number,check in the fridge section on the right hand wall near the ceiling and you should see a tag with the number on it.also down at the bottom kickplate,you can remove the kickplate and there should be a tech sheet tucked away in it,read it and it will tell you how to put the machine into defrost mode,if you can do this,instead of unplugging it if you have to melt it out with the hair dryer you can put it into defrost so the heater will come on and this will help you to defrost the vents quicker.let me know what you find and if you need any more help.good luck with your machine

do a total, 24hour,defrost,with the doors open,(loads of towels)this should melt all the ice you cant see/get at.DO NOT use hairdryers/scrappers as they only do the surface ice.Wash out/spray all vents/drains with clorine bleach.(clorine is a gas and the smell will not permeate food if left to vent naturally) then switch onto fast freeze,check door seals are tight all round(hot cloth will help mould them).hope all works well for you/please leave feedback.ta!

Usually on bottom freezer fridges, there are two vents at the bottom of the freezer compartment where the cold air goes back into the freezer (cold air enters the fridge through the vent at the top/back of the fridge.)

If the vents at the back of the fridge are covered, the cold air will settle to the bottom of the fridge after it enters, and freeze your vegetables. The problem could be caused by ice build up in the evaporator coil of the freezer section also, but this will probably warrant a checkup from a pro.

One thing that can cause ice to build up inside those vents is moist air seeping in through a faulty door gasket. A thin coat of ordinary Vaseline on the gasket surface can help it make a better seal.

First thing to try is Powering off the FF at the mains supply and leaving it standing for 30 minutes. Make sure that you do not open any of the doors or touch any of the controls during this time. Then reconnect the power and wait for 30 to 60 minutes to see if the fault remains or is cured. Try completely defrosting the FF as despite common belief these units are not totally frost free.

In side by sides if the freezer side is working OK and the fridge side is not working correctly it means that air ducting has iced up or the air vent from the freezing unit to the fridge compartment has stuck in the closed or partially closed position which causes the fridge to not be any where near as cool as it should be. If it is too cold then the vent is stuck in the open position and the fridge temperature will continue to fall and become the same as the freezer, thereby freezing the contents of the fridge compartment. It can also get stuck in another position so that if the temperature is adjusted on the front panel then nothing happens to the temperature in the fridge compartment. The vent, which is usually at the top of the fridge compartment on the side where it joins the freezer compartment, is controlled by a small sync motor and either the motor has become faulty, the control module is faulty or the vent is iced up. It can be come iced up by putting too many hot items in the fridge so the steam condenses and freezes the vent in position and then the motor cannot open or close it causing it and / or the control module to become faulty. Other times it is just old age that causes the motor and / or the control module to fail. If the sync motor and vent are working OK then there may be a fault with the fridge temperature sensor or main on board controller that will mean that the sensor or the controller will need replacing.

You can use a hairdryer on the frozen parts.
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp ..

Either the freezer continues to freeze up (most likely due to low refrigerant, due to a leak), or there is an obstruction between the freezer and the refrigerator (refrigerators get their cooling from the freezer).

Given that it works after you defrost it, I'm going with low gas. Call a professional to see if the leak can be fixed. If the unit is more than 10 years old, just get a new one.

replace the cold control
