Reset the filter light by pressing and holding the filter button for three seconds
The filter light on a Samsung refrigerator tells you when the water filter needs replacing. Once you install a new filter, the light will not turn off by itself — you have to reset it manually by pressing the filter button. The exact location and method depend on your model, but most Samsung refrigerators use a button on the control panel inside the fridge or on the exterior ice/water dispenser.
The reset takes about three seconds and requires no tools or special knowledge. If you have just replaced your filter and the light is still on, a reset is the next step. If the light comes back on within a few weeks of a new filter, the filter itself may be faulty or installed incorrectly.
Key Takeaways
- The filter button is usually located on the control panel inside the refrigerator, near the top, or on the exterior ice and water dispenser panel.
- Press and hold the filter button for three seconds until the light blinks or disappears, then release.
- The light will not reset until a filter is physically installed in the unit.
- If the light returns within weeks of a new filter, check that the filter is seated fully in its housing and that you used a genuine Samsung replacement.
Locate the filter button on your model
Samsung refrigerators have the filter button in one of two places. On most models with a top-mounted ice maker or side-by-side layout, the button is on the interior control panel, usually in the upper right corner inside the fridge compartment. Look for a small button labeled "Filter" or with a water droplet icon.
On models with a bottom-mounted ice maker or French-door design, the filter button is often on the exterior dispenser panel — the same panel where you press for ice or water. Check both locations if you cannot find it in one place. Your model number, printed on a sticker inside the fridge or on the back wall, can help you find the exact location in your user manual if you are still unsure.
Press and hold the filter button for three seconds
Once you have located the button, press it firmly and hold it down. Count to three slowly, or watch for the light to blink or change color. Most Samsung models will show the light turning off, dimming, or blinking green to indicate the reset is complete. Release the button after three seconds.
If nothing happens after three seconds, the filter may not be installed correctly. Remove the filter cartridge, check that it is the right size for your model, and reinstall it by pushing it straight in until you hear or feel a click. Then try the reset again.
Confirm the light has reset
After you release the button, the filter light should be off or show a different color — usually green instead of red or orange. If the light is still on after the reset, wait a few seconds and try again. Sometimes the system needs a moment to register the new filter.
If the light remains on after two or three attempts, unplug the refrigerator for 30 seconds, then plug it back in. This resets the control panel and often clears a stuck light indicator. Once the fridge restarts, try the filter button reset one more time.
What to do if the light will not reset
A filter light that will not reset usually means the filter is not installed. Samsung refrigerators have a safety feature that prevents the light from resetting until a filter cartridge is physically in place. Check inside the filter housing — on most models this is a cylindrical compartment in the upper right interior corner or behind a panel on the exterior. Make sure a filter is fully seated and locked in.
If a filter is installed and the light still will not reset, the filter may be the wrong model for your refrigerator. Check your model number against the filter packaging or the Samsung website to confirm you have the correct replacement. Using a non-Samsung filter or a filter designed for a different model can also trigger this problem.
Replace the filter if the light returns quickly
If you reset the light and it comes back on within a few weeks, the filter itself may be defective or you may have installed it incorrectly. Remove the filter and look for a plastic cap or protective cover still on the inlet or outlet — this must be removed before the filter will work. Also check that the filter is pushed all the way in until it clicks; a partially installed filter will clog quickly and trigger the light.
If the filter is installed correctly and the light still returns within weeks, contact Samsung or your retailer about a replacement filter. Defective filters are uncommon but do happen, and Samsung will usually replace one under warranty if it fails prematurely.
Frequently Asked Questions
Where exactly is the filter button on my Samsung refrigerator?
It is either on the interior control panel in the upper right corner of the fridge, or on the exterior ice and water dispenser panel. If you cannot find it, look up your model number on the Samsung website or in your user manual — the exact location varies by design.
Do I have to replace the filter before I can reset the light?
Yes. Samsung refrigerators will not let you reset the filter light unless a filter cartridge is physically installed in the housing. If the light will not reset, check that a filter is fully seated in its compartment.
How long should I hold the filter button?
Press and hold for three seconds. You should see the light blink, change color, or turn off. If nothing happens after three seconds, release and try again after waiting a few seconds.
The light came back on two weeks after I reset it. What went wrong?
Check that the filter is fully inserted and locked in place — a loose filter clogs quickly. Also confirm you installed a genuine Samsung filter designed for your model. If both are correct, the filter may be defective and should be replaced.
Can I reset the filter light without installing a new filter?
No. The refrigerator will not allow a reset unless a filter is installed. If you want to turn off the light temporarily, you must have a filter in the housing, even if it is an old one.
