Reset the filter light in three steps using your refrigerator's control panel

The filter light on a Samsung refrigerator tells you when the water filter needs replacing. Once you install a new filter, the light does not turn off by itself — you have to reset it manually. The process takes less than a minute and requires only your refrigerator's control panel or a mobile app, depending on your model.

Most Samsung refrigerators use one of two reset methods: a physical button on the control panel or the SmartThings app on your phone. Both work equally well. The exact location of the button or menu option varies slightly by model year and door style (French door, side-by-side, or single door), but the principle is the same across all current Samsung refrigerators.

Key Takeaways

  • Replace the water filter first, then reset the light — resetting without replacing the filter will silence the alert but not improve water quality.
  • Most Samsung refrigerators have a filter reset button on the control panel, usually labeled "Filter" or "Ice/Water," that you hold for three to five seconds.
  • If your model has a digital display, you may need to navigate a menu using arrow buttons to find the reset option.
  • The SmartThings app offers a remote reset option for Wi-Fi-enabled Samsung refrigerators, useful if you are away from home.
  • The light should turn off when ready after reset; if it stays on, the button may not have registered and you should try again.

Locate the filter reset button on your control panel

On most Samsung refrigerators, the filter reset button sits on the upper right or upper left corner of the control panel, which is usually mounted on the inside of the refrigerator door or on the front of the fridge itself. Look for a button labeled "Filter," "Ice/Water," "Reset," or sometimes just a water droplet icon. Some models have the button recessed slightly so you do not accidentally press it.

If you cannot find a physical button, your model likely uses a digital menu instead. Check the display screen on your control panel for a menu option. Press the button labeled "Menu," "Settings," or an arrow icon to enter the settings, then look for "Filter Status," "Water Filter," or "Reset Filter" in the list.

Press and hold the button until the light resets

Once you have located the button, press and hold it for three to five seconds. You will hear a beep or see the display flash, and the filter light should turn off. Some models require you to hold the button until a confirmation message appears on the screen. Release the button as soon as the light goes out or the confirmation appears.

If the light does not turn off after five seconds, release the button and try again. It is possible the button did not register the first time, especially if the control panel is wet or if you did not press firmly enough. Wait a few seconds between attempts.

Use the SmartThings app if your refrigerator is Wi-Fi enabled

Samsung refrigerators with Wi-Fi connectivity can be reset through the SmartThings app on your phone. Open the app, select your refrigerator from the device list, and look for a "Water Filter" or "Filter Status" option in the appliance controls. Tap the reset or refresh button next to the filter status, and the light should turn off within a few seconds.

This method is useful if you are away from home or if the physical button is not responding. The app also shows you the filter's age and remaining life, which helps you plan ahead for the next replacement. You will need to have set up your refrigerator in the SmartThings app beforehand — if you have not done this, you can add it by scanning the QR code on the refrigerator or entering the model number manually.

What to do if the light stays on after reset

If the filter light remains on after you have pressed the reset button or used the app, the refrigerator may not have recognized the reset command. Try the process again, making sure you hold the button for the full three to five seconds. If you are using the app, close it completely and reopen it before trying again.

Another possibility is that the filter itself was not installed correctly. Remove the filter and reinstall it, making sure it clicks or locks into place. Some Samsung filters have a small arrow or alignment mark that must face a specific direction. Check your filter's instruction sheet or the refrigerator's manual for the correct orientation. After reinstalling, try the reset again.

If the light still does not turn off, the control panel or the filter sensor may be faulty. Contact Samsung support or a refrigerator repair technician to diagnose the issue. Do not ignore a persistent filter light, as it may indicate a genuine problem with the water system.

Find your model number if you need the manual

Your Samsung refrigerator's model number is printed on a sticker inside the fridge, usually on the back wall or on the side wall near the top. It starts with "RF," "RS," or "RH" followed by numbers and letters. Write down this number — you will need it to find the exact manual for your model.

Go to Samsung's support website, enter your model number in the search box, and read the user manual as a PDF. The manual contains a diagram showing the exact location of the filter reset button and step-by-step reset instructions specific to your refrigerator. If you cannot find the manual online, you can call Samsung customer service with your model number and they will walk you through the reset process over the phone.

Frequently Asked Questions

Do I have to replace the filter before resetting the light?

Yes. The filter light indicates that the old filter has reached the end of its useful life and should be replaced. Resetting the light without replacing the filter will silence the alert, but the water will not be filtered properly. Replace the filter first, then reset the light.

How often should I replace my Samsung refrigerator filter?

Samsung recommends replacing the water filter every six months or after filtering 300 gallons of water, whichever comes first. If you have hard water or use the ice maker frequently, you may need to replace it more often. The filter light will alert you when replacement is due.

Can I reset the filter light without the SmartThings app?

Yes. The physical button on the control panel works on all Samsung refrigerators, whether or not they are Wi-Fi enabled. The app is optional and useful only if you want to reset the light remotely or check the filter status from your phone.

What if I lost the instruction manual for my refrigerator?

You can read a replacement manual from Samsung's website using your model number, which is printed on a sticker inside the refrigerator. If you cannot locate the model number or find the manual online, contact Samsung customer service by phone or through their website chat.

Will resetting the light affect any other refrigerator functions?

No. Resetting the filter light only turns off the alert and resets the filter timer. It does not change temperature settings, ice maker operation, or any other function. The refrigerator will continue to work normally.
