Is your Samsung refrigerator freezing your food in the fridge section? Mine was getting too cold and freezing all my veggies causing me to throw away food and waste money. I replaced the thermostat and Defrost heater on mine. It was not a difficult a repair, I just bought the wrong part the first time. When I looked up my model number it was referencing the wrong part, so the manufacturer must have made a change. MAKE SURE you go based off the part number and not the model number on your fridge. They even make it easy by putting a QR code on the part. Just point the camera on your phone at it and it will open open your web browser on your phone and take you to a list of web sites that list that part, including Amazon. I chose to see if I could find the part locally to avoid waiting for shipping time and to support a local small business, cuz you know Jeff Bezos has enough money.

You can do this, no need to call an expensive repair person over. Part was $60 but you can get it online for even cheaper. I just wanted to support a local small business and not that corporate giant the jungle.

Still freezing my food after a couple of days. Gonna have to call a repair person unfortunately and see what they say. If it's electronics, it's out of my ball field.

Samsung Model# RF23HCEDBSR
Part # DA47 00244U

If your fridge uses part DA4700318M pretty much same process, even easier if you just wanna change the thermostat.
