Water is causing ice to build up in bottom of freezer compartment. I believe it happens when the ice maker fills.

Ok Randy, Lets fix it.

My name is Peter. I am a retired refrigeration field service technician.

You are not getting cooling air to your ice maker freezer compartment. Once again Samsung - bad design - put a ice maker in the fresh food section.

So, you have a ice maker enclosed next to the fresh food section where the recommended temperature setting is 35-40 degrees F.
Where as your recommended freezer temperature is +2/-2 degrees F.

There is a air damper/vent from the bottom freezer in the back of your ice maker housing. Lets remove the ice maker to check for ice build up. On the left hand side of the housing on the wall there is a long narrow cover plate. This is where you connector harness is located. There are 2 screws holding the front end in and a tong and groove tab in the back. Remove the cover plate.

Now, pull the harness out.

Lets remove the ice maker assembly. There are two screws in the front end securing the ice maker to the top of the casing. These screws are recessed. They are either Philips heads or hex heads (1/4"). If they are hex head, he recessed hole diameter is small. Some hex head hand tools will not fit. A screw gun will work or a small outside out side diameter hex head hand tool.

Remove these screws. In the back in each corner is a tong & groove. Pull forward to release the ice maker. Using a small flat head screw driver wedge the wire harness to release. Set the ice maker aside.

Inspect the air vent/damper for ice build up. Use a hair dryer to defrost.

I do not believe you have a automatic damper controlled by a thermistor (temperature sensor). If you do, Remove the damper assembly. Get your multi-meter. Set your meter to the lowest Ohm reading (Omega on your meter) Touch the two probes on your meter together, you meter should read 1.0. Disconnect the 2 motor contacts. On the motor place one probe on one contact and one probe on the other contact. If the meter still reads 1.0 the motor is bad. If the meter reads 0-50 Ohms the motor is good.

If there is no ice buildup & the damper motor checks out, replace the temperature sensor.

You will find getting the wiring back into the side panel will be a little difficult. As usual, Samsung is not service friendly.

I would replace the water filter first off. If you have completed that already then I would check the water fill outlet for calcium build up. If that is clear, check to make sure the solenoid is energizing for the fill. If you have water to the basin and it is still not working I would have to check the timer to see if it is initiating a cycle for the ice.

please check your ice maker to make sure it is not jammed up water can leak into fridge

I've just had a similar problem. I fixed it by removing the large panel on the back of the inside of the freezer. I found a large build up of ice at the bottom of the freezer which seems to have developed because the drain hole at the bottom of the freezer was blocked. I defrosted the ice, cleared the drain and now the freezer is working fine.

you can check the fill tube in the freezer make sure it is not blocked with frozen water. if you can disconnec the water supply line from the fill tube try and reset the ice maker to advance it to a new cycle and if water come out of the supply line the you knwo there is a blockage if no water comes out the the ice maker may be bad or the fill valve is bad. last thing you may need to call a service tech out to find the problem.good luck i hope that this has helped some what.i would like to knwo how thing go for you

Is the ice tray that fills level? this may be over flow from the tray filling sequence

The fill valve for the ice maker could be stuck partially open and dripping into the ice maker. If this is the case shut off the water line to the ice maker and if the water stops you will need to replace the ice maker fill vavle

Has this thing a separate frezer and cooler compartment.
Have tried to completely defrost and clean that thing.
At times like in airco's the pinch valve for the cooling process to effect (expansion) is stuck frozen, or very seldom broke.

Hi TJ,

It'll cost around $65.00 to take care of this problem. The problem is the water inlet valve. The part number is 4389177 and can be picked up at your local appliance parts retailer or you can get one online maybe for a better price (just plug the part number into your favorite search engine).

Here's what's happening... The valve I mentioned is actually a "dual coil" unit. One coil supplies the cold water, the other feeds the ice maker. These "coils" are independant of each other, so one coil can fail and the other can keep on truckin', no problem. But what you have is an Ice Maker coil/valve that is weak and it's allowing water to bypass.

Basically the IM valve isn't closing shut completely. Imagine a dripping faucet... that's what it's like except you can't hear the drops, you can only see the results. Imagine drop by drop rising up that tube behind the fridge and into the IM. One drop at a time. These drops of water go into the freezer compartment through the IM fill tube. Now when these little ***** drops slide down the fill tube inside the freezer compartment they flash freeze before they reach the IM. One drop after another... drip drop drip drop. All these little droplets of water eventually form a glacier inside the fill tube. 

OK, now we're at the point of glatiation. The fill tube (just behind the ice maker) has completely frozen solid. Now... when the IM "calls" for water to refill itself, the (failed) valve opens up and lets full pressure through. But where is this water/pressure going to go? The pressure builds inside the 1/4" water line until it can't handle it any more, the pressure looks for the path of least resistance. That path is the connection that you found loose. It blew out because the fill tube (into the freezer) is blocked with ice and the reason it's blocked is because the valve isn't shutting off completely.

That's alot of words to say this... it's an easy fix. Get the valve (above). Pull the fridge out. Unplug it. Turn the water off at the wall. Remove the water line going into the valve and set aside. Remove the cardboard panel. Remove the 2 screws holding the valve to the fridge. Pull the valve out. Note the electrical and tubing connections carefully. Get your new valve out and install the electrical and tubing just like the old one. Then rebuild, turn on the water and look for any leaks (use a flashlight and take a minute or two here... finding a leak now will save you alot of misery later). Replace the cardboard and plug it back in.

There ya go! Your first major appliance repair job done successfully? Priceless.

turn off the power to the appliance and apply a hairdryer to the ice maker compartment for about 2 mins , worked for me.
