Check ur door seals if air gets in it will condensate and accumilate water at bottom, also ur condensation plug line may be blocked or plugged with debris? hence water moister runs down to crisper. u can clean out the line with a thin wire or coat hanger but be careful
freezing of the water line is a sure sign that the water tank is icing up - possibly due to a failing defrost coil.
This is a common problem with Samsung - as I have just discovered! I had a different model from you but the same symptom- the line freeze, followed by the fan making a loud whirring noise and the temperature being all over the place.
The water tank is in the right fridge compartment behind the bottom drawers. Take the drawers out and have a look at yours.
Ice will be on the outside of the tank. If there is no sign of ice then the problem lies elsewhere.
So.....if its iced up you should get hold of a coil replacement kit on Ebay and sort it. It is very straight forward to do and the company I got my kit from provided a link to their YouTube video showing how to do it. Go look here - https://www.youtube.com/watch?v=DO2wDd16OkA
Before you do the repair you will need to defrost the unit, switching it off for at least 2 days until there is no sign of ice on the water tank. You will need to store food elsewhere!!
It takes a couple of hours to replace everything and I also bought a couple of small, battery powered digital thermometers for inside each compartment. This allows you to check that the temperatures are where they should be and the system is working. These were a couple of dollars each and well worth it.
The YouTube link should show you the supplier of the parts and they should be able to ship worldwide - just check your model number against their kits to find the right one.
Hope this is of some help.
Check frosting over would have clogged the drain pan. Unplug unit and wait for sometimes until defrost is over. Then run the unit. Please confirm, defrost timer,thermostat and heater are working properly to get auto defrosting time to time.Thanks.
Thaw the freezer section out and while the unit is off lift the pan from the bottom rear slightly and slide it toward you. be careful because the pan will probably be full of ice and water and it will give you a cold shower if you pulled it hard.
Most times that will be the water control valve on the rear of refrigerator and most times they come as a pair or dual one side for water dispenser and other side for the ice maker. You can test to see if the ice maker is defective by turning switch on and fill with tap water. When it freezes and dumps but no water refills the ice maker then the valve for the ice maker side is defective and will need to be replaced as a pair. If you fill ice maker with water and it freezes and then does not dump then most likely the ice maker is defective.Thnks Sea Breeze
If the refrigerator wont stay on the start relay may be defective. This may have been caused by the leaking door that overloaded the system. The relay is a small box mounted to the side of the compressor and provides power to the compressor start winding for a split second at start-up to help get the compressor get started. If its defective the compressor may run off and on (a lot) or not at all and the refrigerator will not get cold enough. Fairly easy to do and reasonable
