Reset the filter light in three steps
The water filter light on a Samsung refrigerator resets by holding a button on the control panel for three seconds. The exact button and location depend on your model — some have a dedicated filter reset button, others use the power freeze or power cool button. The light will blink once or twice, then turn off. This tells the refrigerator you have installed a new filter and resets the 6-month countdown timer.
You do not need to remove the old filter or do anything else before resetting the light. The reset is purely a timer reset. If you have not actually replaced the filter, the light will come back on in six months anyway, so there is no harm in resetting it early if you are testing the button or if you replaced the filter before the light came on.
Key Takeaways
- Hold the filter reset button (or power freeze/cool button on some models) for three seconds until the light blinks and turns off.
- The reset button location varies by model — check your refrigerator's control panel or your user manual to find it on yours.
- Resetting the light does not replace the filter; it only resets the timer that tracks when the next replacement is due.
- If the light comes back on within a few weeks of resetting, the button may not have been held long enough, or the control panel may need a power cycle.
Find the reset button on your control panel
Samsung refrigerators place the filter reset button in different spots depending on the model year and style. On many models, a button labeled "Filter Reset" or with a water droplet icon sits on the upper right or left corner of the control panel. On others, the power freeze button (usually on the left side) or power cool button (usually on the right side) doubles as the filter reset when held down.
If you cannot find a dedicated filter reset button, check the user manual that came with your refrigerator. You can also find the manual online by searching "Samsung [your model number] manual" — the model number is printed on a sticker inside the refrigerator, usually on the back wall or on the side wall near the top. The manual will show you exactly where the button is and how long to hold it.
Some newer Samsung models with digital displays may have a filter reset option in the settings menu instead of a physical button. If that is the case, use the arrow buttons to navigate to settings, find the filter or water option, and select reset.
Hold the button until the light responds
Press and hold the filter reset button for three seconds without releasing. You should see the filter light blink once or twice, then turn off completely. If the light does not respond after three seconds, keep holding for up to five seconds — some models need a longer press.
If the light still does not turn off, release the button, wait ten seconds, and try again. Sometimes the control panel needs a moment between attempts. If it still does not work after two or three tries, unplug the refrigerator for five minutes, plug it back in, and attempt the reset again. A power cycle can clear a stuck timer.
What to do if the light comes back on quickly
If the filter light turns back on within a few weeks of resetting it, the button press may not have registered fully. Try the reset again, this time holding the button for a full five seconds and listening for a beep or watching closely for the light to blink. Some models give a subtle response that is straightforward to miss.
If the light comes back on after you have reset it multiple times, the control panel itself may be malfunctioning. Contact Samsung support with your model number, or have a technician inspect the control board. This is rare, but it can happen if the panel has been exposed to moisture or power surges.
Understand what the filter light actually tracks
The filter light is a timer, not a sensor. It does not detect whether the filter is dirty or working — it straightforward counts down from six months and turns on when the time is up. Resetting it tells the refrigerator that you have installed a new filter and restarts the six-month clock.
If you replace the filter before the light comes on, you can reset the light at that time. If you wait until the light comes on, reset it after you install the new filter. Either way, the light will come back on in approximately six months, depending on your water usage and the model.
Replace the filter if the light is on for the first time
If the filter light just came on and you have not replaced the filter yet, do that before resetting the light. Samsung filters are model-specific, so order the correct part number for your refrigerator. You can find the part number in your manual or on Samsung's website by entering your model number.
To replace the filter, locate the filter housing — usually in the upper right corner inside the refrigerator or in the base grille at the bottom front. Turn the old filter counterclockwise to remove it, then screw the new filter in clockwise until it is snug. You may see a small amount of water drip out; this is normal. Run water through the dispenser for 30 seconds to flush the new filter before drinking from it.
Frequently Asked Questions
Do I have to replace the filter when the light comes on?
No, the light is a reminder based on time, not water quality. If your water usage is light, you can wait longer. If it is heavy, you may want to replace it sooner. Samsung recommends every six months as a general guideline, but your actual need depends on your household water usage and local water quality.
What happens if I reset the light without replacing the filter?
Nothing bad happens. The light will straightforward come back on in six months. Resetting the light does not affect the refrigerator's operation or water quality — it only resets the timer. If you want to test the reset button or reset it early, there is no penalty.
Can I reset the filter light from the refrigerator's app or settings menu?
On some newer Samsung models with Wi-Fi and a companion app, you may be able to reset the filter through the app or the refrigerator's digital menu. Check your user manual or the app itself for a filter or water settings option. Older models require a physical button press only.
The reset button is not working. What should I try next?
Try holding the button for five seconds instead of three, or try a different button if your model has multiple options (power freeze or power cool). If that does not work, unplug the refrigerator for five minutes and try again. If the light still will not reset, the control panel may need service.
Where do I buy replacement filters for my Samsung refrigerator?
Samsung filters are sold at major appliance retailers, online marketplaces, and directly from Samsung's website. You can also find them at some grocery stores and home improvement stores. Always check the part number on your old filter or in your manual to make sure you order the correct one for your model.
