Fridge keeps on freezing up and freezing contents, no matter how low setting is.

fridge settings work in reverse to freezer settings
1 for a fridge is almost freezing where it should be around 4
cold air sits at the bottom of the fridge so the setting will be colder in the crisper draw that at the top shelf

Hi,I had trubble with my fridge so done a bit of reserch the main reason for the fride freesing up is,
fridge not set at right temp (3 to 7 c ) or vent where water drains blocked,shelves not in right place as in manuel,and if you put veg that has alot of mosture content can also course freezing at the bottom of the fridge,hope this was some help,maybe buy a fermomiter to test.

maybe the fridge is set on a colder setting and if that's not it then stick it on the lower shelves and that might help from not freezing because are fridge is the same way when it is stuck by the coolant fan

Your t'stat is probably bad. Should be easy to fix. At least it is freezing and not ruining your food from being too warm.

One of the most common problems with freezers is their tendency to build up a thick level of frost and ice that can disrupt performance. The ice can form on the hoses and cause the fan to freeze up. While you want the freezer to be cold, too much ice is not good for the freezer or the food inside it. There are multiple reasons a freezer could start to develop frost buildup.

Freezer Overstocked
Frost can build up in the freezer if there are too many items inside of it. Air cannot properly circulate around the freezer, so the areas with the sitting cold air can freeze the moisture. Frost continues to build up and accumulate, which then allows it to spread. If food is stocked up near the fan, cold air can't get past it, and the fan itself could develop frost to the point where it freezes and stops working entirely. This can be prevented by not overstocking the freezer and by evenly distributing food throughout.

Temperature Setting Too Low
The freezer should have a thermostat that regulates how cold it gets. If the temperature is set at too low of a setting, the freezer kicks into high gear, the air freezes outright and frost quickly builds up. Adjusting the thermostat to a higher temperature or level can counteract this problem, but you may need to de-thaw the freezer to eliminate the frost that has already built up inside.

Keeping the Fridge Door Open
Many people keep their fridge door open for extended periods of time while they examine the contents inside to see what they want to eat. This can contribute to frost buildup in the freezer, because the fridge is taking in a lot of warm air during this process and the fan pushes it up into the freezer. The moisture in that air is then quickly frozen, and ice can build up substantially as a result. The longer the fridge door is held open, the more likely this can occur, so the best solution is to only keep the fridge open for short intervals and then to not open the door again for a while.
Hope this tips will help you. : )

There's a little dial or knob to set the temperature of your fridge, just wind it down to about 4 if it has a number setting and that should keep from the contents freezing up.

The 643V has an issue that it can freeze the water in the line during winter.
You must switch the fridge off until the water starts to run again. Then set the temperature of the fridge up as high as possible in winter. Draw 1 litre of water at least twice a day during winter.

This fixed my problem.

You can set the tempertaure back down in the fridge during summer without a problem.

only one thing that can do this.. your thermostat.. its either broken or set to low

In spite of keeping the temperature regulator 'Low' mode if it freezes up so fast, that means there is a problem in the freez pipe from where the cool air is coming into the freezer. Please check on that. Make sure, that u defrost it once in a week.

thanks,
