Icicles in the freezer, fridge not getting cold enough. could the freezer door have been left open and caused ice build up in the vent leading to the fridge to keep the fridge cold?

Check that the fan is running at the back of the freezer section. If it isn't, the freezer will continue to get colder but as the air is not moving around the cabinet, you get areas of ice buildup. The fan is usually at the top of the back panel, With the fridge unplugged, remove the panel in front of the fan motor. You can otherwise check if the fan is running by pressing the door switch whilst the freezer door is open. If the fridge is running, when you press the switch, the light should go out and the fan should start.

My freezer is working but my freige is not working what should I do

Good day,
There are 2 vents. The one on the top to allow air from the freezer into the fridge. There is a second one, a return on the bottom left that allows the air to return to the freezer.
The return vent is the one that is blocked. (iced up).
On your model, it is very difficult to melt the ice out especially using heat due to all the plastic and foam.
Although ugly, it is best to unplug the machine, and leaving both doors open fo 24 hours.

defrost the freezer.

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.

hi this might help you:

*make sure that the seal indeed still seal well enough...
*the older the fridge the more common this is

i don't really know much about this, but just check that it's cold enough inside like check if it changes when you change it from eg 4 to 7, and that the sealing is fine, and that your door is lined out good, also important that last thing offcourse, cause if it seems to shut good, but the seals arent in the right position compared to the other side (the 'fridge-walls' :p) they won't seal ofcourse...

I hope this is useful, and greets.

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. The ice may have also stopped up this opening blocking the air flow.Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

Need to defrost fridge completely for about a day then switch on again. Possibly door was left ajar on freezer, or auger motor iced up due to product being to close to outlet..

the little fan motor in the freezer is defective.  It may only be stuck.  

Here's what I did, I defrosted! I found out that the fridge temp is monitored and maintained by the freezer. Because we had a power outage one night, my freezer thawed while we all slept and then when power came back on, freezer re-froze but this cause an ice build up on the vent on the back wall of the freezer. Well, ice must have been in one (or more) vents, causing blocked air flow in my top half of the refrigerator. I turned the dial in the freezer to "off" which also shuts down power to the fridge half. I then unplugged the refrigerator, hauled all my food items into coolers, opened the freezer door and refrigerator doors and left them open for a little over six hours. I took advantage of this empty fridge and freezer and wiped everything down. After this time frame passed, I plugged the fridge back in, turned the freezer dial to my preferred freezer temp, and wah-lah! Within two hours I had a cold fridge and solid ice cubes in the freezer. I then put all my food items back into their appropriate compartments, and went to work. Bear in mind, a total 24-hour period is needed for the fridge to re-set itself, but still, after two hours the fridge was noticeably cold. Who knew, besides our parents' generation: DEFROST!
