Find Your Samsung Model's Control Panel
The steps to change your Samsung fridge temperature depend on which control panel your model has. Samsung refrigerators use one of three setups: buttons on the front of the fridge, a digital touchscreen on the door, or a smartphone app. Locate which one you have before you start — it will save you time looking for controls that don't exist on your unit.
Check the front of your fridge first. Most Samsung models made in the last ten years have either a row of physical buttons near the top of the door or a small digital display screen built into the door itself. If you see neither, your model may use the SmartThings app on your phone instead. Your model number is printed on a sticker inside the fridge, usually on the back wall or the top shelf — you can search that number on Samsung's website to see which control method applies to you.
Key Takeaways
- Samsung fridges use physical buttons, a touchscreen panel, or a smartphone app to adjust temperature, depending on the model year and features.
- The fridge and freezer compartments have separate temperature controls, and changing one does not affect the other.
- Most Samsung models let you set the fridge between 34°F and 46°F and the freezer between −4°F and 0°F.
- If your fridge has a digital display, hold the button for two to three seconds to enter settings mode rather than just pressing it once.
- After you change the temperature, wait at least four hours before checking whether the compartment has reached the new setting.
Using Physical Buttons on the Door
If your Samsung fridge has buttons on the front of the door, look for buttons labeled "Fridge" and "Freezer" or marked with up and down arrows. Press the button for the compartment you want to adjust — fridge or freezer — then use the arrow buttons to raise or lower the temperature. Each press usually moves the temperature by one degree.
Watch the display as you press. Most models show the current temperature setting on a small screen above or next to the buttons. Stop pressing when you reach the temperature you want. The fridge will not change its actual temperature when ready — it takes several hours for the compartment to cool down or warm up to the new setting, so do not adjust it again right away if it feels the same after a few minutes.
If your buttons have no display screen and you cannot see what temperature you are setting, count your button presses. Write down how many times you pressed up or down, then wait four hours and check the temperature inside the fridge with a thermometer. This tells you how many presses equal one degree on your model.
Using a Touchscreen Control Panel
Samsung models with a digital touchscreen on the door usually have a home screen showing the current temperature of both compartments. Look for icons or text that says "Fridge" and "Freezer" with numbers next to them. Tap the number or the compartment name to enter the temperature adjustment screen.
Once you tap, the screen will show the current temperature and let you increase or decrease it. Use the on-screen plus and minus buttons or swipe up and down, depending on your model. The screen will confirm your new setting — read it carefully before you leave the menu, because some models require you to press a "Confirm" or "Save" button to lock in the change.
If the touchscreen is unresponsive, try pressing and holding your finger on the button for two to three seconds instead of tapping quickly. Touchscreens on refrigerators sometimes need a longer press to register. If it still does not work, the screen may need cleaning — wipe it gently with a soft, slightly damp cloth and try again.
Controlling Temperature Through the SmartThings App
Newer Samsung refrigerators with Wi-Fi can be controlled through the SmartThings app on your phone. read the app from your phone's app store, sign in with your Samsung account, and add your fridge to the app by scanning the QR code on the fridge or entering its model number. Once the fridge is connected, open the app and look for a temperature control card or tile.
Tap the fridge or freezer compartment, then adjust the temperature using the on-screen slider or plus and minus buttons. The app shows you the current temperature and lets you set a new one. Changes made through the app take effect the same way as changes made on the fridge itself — the compartment will gradually reach the new temperature over several hours.
If the app shows your fridge as offline or disconnected, check that your fridge is plugged in and connected to your Wi-Fi network. Restart the app and try again. If it still will not connect, restart your fridge by unplugging it for thirty seconds, plugging it back in, and waiting two minutes for it to boot up before opening the app again.
Recommended Temperature Settings for Food Safety
The U.S. Food and Drug Administration recommends keeping your fridge at 40°F or below to slow bacterial growth. Most Samsung fridges let you set anywhere from 34°F to 46°F. If you want your food to last longer, set it closer to 34°F or 35°F. If you notice food freezing on the shelves, raise the temperature by one or two degrees.
For the freezer, keep it at 0°F or below. Samsung freezers typically range from −4°F to 0°F. At 0°F, frozen food stays safe for months. Do not set it warmer than 0°F unless you are storing food for only a few days.
If you live in a very cold climate or your fridge is in an unheated space like a garage, you may need to set the fridge warmer than usual — sometimes as high as 40°F or 42°F — to prevent it from freezing food. Check the temperature with a thermometer after four hours to make sure it is in the safe range.
What to Do If the Temperature Will Not Change
If you have adjusted the temperature but the fridge or freezer is still too warm or too cold after four to six hours, first check that the door seals properly. Open the door and look at the rubber gasket around the edge — it should be clean and not cracked or peeling. If it looks damaged, the cold air is leaking out and the fridge will never reach the temperature you set. A damaged gasket usually needs to be replaced.
Next, make sure nothing is blocking the vents inside the fridge or freezer. Cold air flows from the freezer to the fridge through vents, usually on the back wall or the side. If food is pushed against a vent, the compartment will not cool evenly. Move items away from the vents and wait another four hours.
If the temperature still will not change, the thermostat or cooling system may be failing. This is a repair that requires a technician — contact Samsung support or a local refrigerator repair service. Do not try to fix the cooling system yourself.
Frequently Asked Questions
Why is my fridge still warm after I lowered the temperature?
The fridge needs four to six hours to reach a new temperature setting. If it is still warm after that time, check that the door closes completely and the rubber seal is not damaged. Also make sure nothing is blocking the cold air vents inside the fridge. If both are fine, the cooling system may need repair.
Can I set the fridge and freezer to different temperatures?
Yes. The fridge and freezer have separate temperature controls, and changing one does not affect the other. You can set your freezer to 0°F and your fridge to 38°F at the same time.
What temperature should I use if I am going on vacation?
Set the fridge to 38°F to 40°F and the freezer to 0°F. These settings use less energy while you are away and keep food safe if the power goes out briefly. Do not turn the fridge off completely — bacteria can grow quickly in a warm fridge.
Does changing the temperature use more electricity?
Setting the fridge colder than necessary does use more electricity. If you set it to 34°F instead of 40°F, your electric bill will be slightly higher. The difference is usually small — a few dollars per month — but it adds up over time.
What if my touchscreen is frozen or stuck?
Unplug the fridge for thirty seconds, then plug it back in. This resets the control panel. If the screen is still stuck, try wiping it clean with a soft, damp cloth — dirt or condensation can make it unresponsive. If it does not work after that, the screen may need to be replaced by a technician.
