Samsung Refrigerator - Twin Cooling - Solving Water Condensation Under the Drawers




Introduction: Samsung Refrigerator - Twin Cooling - Solving Water Condensation Under the Drawers

This is the Samsung Frost Free Bottom Mount Inverse RL62 model, but I believe any model that uses twin cooling or similar system, and have this problem, you can use this guide.

Step 1: The Problem..

The problem is water condensation inside the refrigerator, accumulating beneath the drawers.
On the next steps, I show the possible solution for resolve this problem. Maybe this is a common issue with Samsung's. In my research, I found this site that have the same problem and my solution is based on the same idea from publisher.


Step 2: Disassemble Inside Panel

Remove the three screws indicated on pictures and use the hair dryer or hot air gun, for melting ice forming behind the panel, be careful for not exceed heat and damage the panel.

Step 3: Remove the Painel

Now with carefully move "slower" the inner panel to drop and release the side latches.

Step 4: Disconnect the Connectors

Now, you can disconnect the two connectors, one of the fan and other of temperature probe. Is very easy, the connector have a clip, you press the clip and pull the connector.

Step 5: Acess to the Heat Exchange

If everything it was all right here, now you will have access to the heat exchanger.
Avoid touch in parts the fins, or pipe connections. From here, handling at the heat exchanger parts, should be done with caution, if damage, case it happens, will have serious problems and will have to call technical assistance.

Step 6: Here Is the Problem

This is a clip from drain evaporator, and it have a problem.
This CLIP DRAIN EVAPORATOR not work correctly, because your hot exchange area is small for the defrost heater coil, and not goes inside the drain pipe. It'll warm a small pool of water once the drain is already frozen. For the keep the drain clear, we let's go make a stem extending from the heat coil to water pipe drain (inside) for heat take. I removed the original clip and i did a alternative with hard electrical conductor (Cu). If do you prefer, here the manufacturer has developed a new clip.


Step 7: Hard Exchange Heater

After making a rod like that of copper, 2.5 mm gauge (4mm would be better) will be install there.
Remember that before install this, you need to unclog the drain hole. You must melt the ice from the frozen evaporator drain. The new clip won’t melt the existing ice but it will prevent the ice from building up again. I used very hot water (my wife’s teakettle) and a small syringe. I put hot water into the drain with the syringe. I let it sit for a minute then removed it with the syringe. I repeated the process and after the third time the drain opened up. I added hot water a fourth time to make sure the drain was opened.

Step 8: Drains Output..

Behind the refrigerator, should remove the panel and will see the two outputs of the drain, one of the refrigerator and one freezer.
The water should come out through the second output (3 Picture).

Step 9: Installed and Finished

I fixed the rods in heater coil with 1mm thick copper wire fixing with 5 on each side like on picture.

Step 10: Video How I Did, in Portuguese Br

Here has a video of the process.
I hope to have helped in some way.

    Question 2 years ago on Step 4

    Why the fridge is not restating again after defrost circle?


    Answer 2 years ago

    Samsung programs their refrigerators that the freezer must be at a certain temperature before cooling down the refrigerator compartment. If this is consistant then you have other issues.


    My samsung fridge keepe thawing n then refreezing how do i diganose it

    You need to remove the coil cover and check the drain, it may be plugged. Or pull the refrigerator out and check the drain pan at the bottom of the refrigerator. There should be water in it after a defrost cycle. If not the drain is plugged. Hours after a defrost cycle the condensate could have evaporated and the pan would be dry. if there is water under the bin drawers, then the drain is plugged.

    Another is the defrost heater is bad and not warming the ice to melt it around the coils. Several ways to diagnostic and you'll need a volt/ohm meter.

    My 8 year old Samsung RF267 French Door started to have this problem. A year ago I moved it to the garage that is usually hot and humid (Florida, USA) and only a few months ago the bottom draw would not open. The entire bottom was iced up and the center wheel of the deli drawn would freeze to the ice. I did this fix and a great one of it. The first problem for icing is the level. If the RF box is not level according to the installation requirements, the drain doesn't work as well and water will lay at the drain hole. If it is level all around and slightly tilted back the water will drain during the defrost cycle.

    Very informative! The fridge where I live has this same problem. Great fix!
