I just bought a house and the refrigerator that came with the deal is a Samsung. After about 3 weeks the refrigerator compartment started freezing the food inside it. It has digital display on the outside between the frigerator and freezer with button temperature controls.I tried unpluging the refrigerator over night and that did not help. I set the temperature of the refrigerator at 40 and the freezer at pulse 4 degrees. I have tried setting the tempuratures at many tempuratures but the refrigerator keeps freezing up. Also, the digital reading on the display is does not seem correct. Please any repair ideas would be appreciated!

You have a bad damper control, or a stuck (frozen or obstructed) damper.

Couldn't tell from the drawings. The only visible board of any kind appears to be located in the rear, near the compressor, probably along the right side as you face the compartment. The damper itself will be between the freezer and refrigerator sections. If it's a motorized damper, you'll need further diagnostics to determine whether it's the motor or the board.

Thank you. There is the digital display with the tempurature control button on the front of the refrigerator between the freezer and the refrigerator compartments. It is easy to remove with just 2 screws. Would it be worth replacing it? Thanks again.

That could be exactly where the damper control is. It's a gamble at this point. If you can expose the damper motor and apply a test voltage to it, you may have a more informed choice. You'll need to access the schematic to see whether it works on high voltage, or low.

No wonder the drawings were confusing...I had only seen this in Sub Zero units. Let's start over: You say the refrigerator freezes. You'll need to remove the panel in the rear, inside the refrigerator, to expose its evaporator. Is it covered with snow-like frost?

Thanks for sticking with me. This is so fustrating. I did open up the rear compartment behind the freezer. The freezer is on the bottom. I vacumed out any dust in the compartment and on the coils. There was very little dust. It is only around 2 years old but not under warranty anymore. To answer your question there was no frost around the evaporators. There is 2 of them. I hope I am seeing the right part. They are 2 black coil units. On one end was the condenser. then the fan. and then the 2 black evaporators. There was no frost in the compartment. Thanks. I have been struggleing with this for about 2 weeks.

If there are two separate systems (one for the freezer, and one for the refrigerator), there will be TWO compressors. If your unit only has one compressor, the evaporator for that unit is INSIDE the freezer, covered by a rear panel. If your unit has two compressors, the evaporator for the refrigerator is INSIDE the refrigerator, also covered by a rear panel. The evaporator is (usually) Aluminum. That's the coil I want you to look at. In normal operation, there is a uniform frost coating over the entire coil. In a faulty defrost situation, you will generally see a very heavy snow-like frost build-up all over the coil, and sometimes enough to make the rear panel bulge inward (toward the food).
CAPITALIZATION is for emphasis only...I'm not shouting.
