Samsung refrigerator problems

Most likely you're correct, the defrost cycle produces water that is supposed to be captured in a holding tray, pan, etc. If the pan is cracked it would leak out or if the drip tube (pipe) is not in place it would miss the pan. It may be easier to remove the contents of the small frige and tip it over some to see what you can down there. I assume this small unit doesn't have any water souce to it (no ice maker or water). Check the tubing for damage and see if you can find the holding pan to inspect for crackes, etc.

Either your water tank in the fridge froze up, the waterline that goes up the freezer door from the bottom hinge froze, or the switch that your glass hits is damaged. Do you hear any humming or noises when you put your glass up to get water?

If there is a reset button on your ice maker try pushing it. Many ice makers have two holes for reset. A general rule of thumb is if the ice maker fingers are stopped in a slightly vertical position then your ice maker unit is working. If the fingers are stopped anywhere else then it needs some sort of attention or replaced. Make sure there is water, or ice in the ice maker tray, if not then the problem is with water supply.

It is probably your defrost cycle causing this. Obviously if you shut the water line off then it is not coming from there so there is only 1 other place it could be. Every 8, 10, or 12 hours depending on you defrost timer the refrigerator will defrost itself.......the frost melts into water and drains into a pan under the fridge. If the drain is plugged then it will just run into the refrigerator. If you have a freezer on top model then just remove the back wall inside the freezer, it will be a few 1/4 inch screws....If you have an icemaker then remove that too, it will be held on with 3 screws. Just look behind that wall and you will probably see ice at the bottom.....defrost the ice and pour a cup or 2 of water into the drain to make sure it is unclogged. If it is still plugged up then you have to find the clog....either in the back of the fridge behind the lower cover or in the refrig compartment near the back of the roof.

Good day,
A step by step procedure should resolve your problem. If the dispenser is working, you can skip that step.

First step is to take a small paper cup of water and fill the cavity until it is near full. With the ice maker turned on, close freezer door and wait 3 hours to see if it harvests. If not, the ice maker is bad, and must be replaced. If the cubes harvest then.......
Three possibilities.
1. The water supply from the house is not delivering water to the water valve. Shut off the house at the meter, disconnect the line going to the water valve, and with the line pointed into a bucket, have someone turn the valve back on for a 15 second count. The water should come out smartly. If not, the line and it's fittings will have to be replaced.
2. The fill tube from the back of the machine that feeds water into the back of the ice maker is frozen up. You will have to remove the ice maker to visually inspect that tube. If blocked, it needs to be defrosted, but use caution. Too much heat too fast will start to melt plastic and vinyl parts you don't want melted.
If this is the case, then once cleaned out, you will have to change the water valve located in the back bottom rear of the machine because it is leaking during the off cycle.
3. If everything checks O.K. up to this point, you will have to purchase and install a new water valve, and install it.
P.S. Under very rare occasions the electric circuity in the ice maker will fail to send a signal to the water valve. Although rare, it can happen, in which case the best option is to replace the ice maker and water valve.
