How to Reset the Filter Light on Your Samsung French Door Refrigerator

The filter light resets after you replace the water filter

The filter light on your Samsung French door refrigerator turns on to tell you 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 reset process takes about 10 seconds and requires only the button on your refrigerator's control panel.

Samsung builds the reset into the same panel where you see the light. You do not need a special tool, a code, or access to any hidden menu. The exact button location varies slightly by model year, but the method is the same across all Samsung French door refrigerators made in the last decade.

Key Takeaways

• Replace your water filter first, then reset the light — resetting without a new filter will silence the warning but leave you with old, unfiltered water.
• The reset button is on the control panel inside your refrigerator, usually labeled "Filter" or marked with a water droplet icon.
• Press and hold the filter button for three to five seconds until the light goes out or changes color.
• If the light does not respond, check your model number on the back wall of the refrigerator and confirm you are using the correct button for your year.

Locate the filter button on your control panel

Open your refrigerator door and look at the control panel on the inside of the door or on the upper wall of the fridge compartment. Most Samsung models have a small button labeled "Filter" or showing a water droplet symbol. On some older models, the button may say "Ice/Water" or "Reset".

If you cannot find a physical button, check your refrigerator's display screen. Some newer Samsung models have a touch-sensitive panel instead of a button. Look for a filter icon on the screen itself. Your owner's manual will show you exactly where it is on your specific model — you can find the manual by searching your model number on Samsung's website.

Press and hold the filter button until the light resets

Once you have located the button, press it firmly and hold it down. Count to three or five seconds while you hold it. The filter light should blink, turn off, or change from red to green, depending on your model. Release the button once you see the change.

If nothing happens after five seconds, release and try again. Some models require a longer hold — up to ten seconds. If the light still does not respond after two or three attempts, the button may not be registering, or you may be pressing the wrong control. Check your model number and manual to confirm you have the right button.

Confirm the light has reset by checking its color or status

After you release the button, look at the filter light immediately. On most Samsung models, a red or amber light turns green or disappears entirely. Some models show a message on the display screen that says "Filter Reset" or "Filter OK". This confirms the reset worked.

The light may take a few seconds to change, so wait a moment before assuming it did not work. If the light is still red or amber after 10 seconds, try holding the button again for a full five seconds. If it remains unchanged after three attempts, the reset mechanism may need service, or the button itself may be stuck.

What to do if the reset button does not work

If the button does not respond no matter how long you hold it, first confirm that you actually replaced the filter. The reset will not work if the old filter is still in place. Remove the filter cartridge, check that it is truly old, and install a new one before trying to reset again.

If you have a new filter installed and the button still will not work, try unplugging the refrigerator for 30 seconds, then plugging it back in. This power cycle sometimes resets the control panel's memory. Wait for the refrigerator to power back up fully — usually one to two minutes — then try the filter button again.

If the light still does not reset after a power cycle, the control panel or the button itself may have a fault. Contact Samsung support with your model number, or contact a refrigerator repair technician who services Samsung units. Do not ignore a persistent filter light, because it may indicate a problem with the filter sensor rather than just a cosmetic issue.

Prevent the filter light from coming back on too soon

The filter light is designed to remind you when the filter has been in use for about six months or 300 gallons of water, whichever comes first. If the light comes back on within a few weeks of resetting it, you may have a faulty filter sensor, or the filter cartridge itself may be defective.

Always use genuine Samsung replacement filters or filters certified to work with your model. Third-party filters sometimes do not trigger the sensor correctly, which can cause the light to behave unpredictably. Check the filter packaging to confirm it is rated for your specific refrigerator model before installation.

Frequently Asked Questions

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

Yes. Resetting the light without replacing the filter silences the warning but leaves you drinking water that has passed through a saturated filter. A clogged filter does not remove contaminants effectively. Always install a new filter first, then reset the light.

What if I reset the light by accident before replacing the filter?

The light will not come back on until the sensor detects that six months have passed or 300 gallons have flowed through. Replace the filter now anyway, and the next time the light comes on, you will know the filter is actually due. You can reset it again once the new one is installed.

Can I reset the filter light from my phone or through the SmartThings app?

Some newer Samsung models with Wi-Fi connectivity allow you to view filter status through the SmartThings app, but most do not allow remote reset. You will still need to press the button on the refrigerator itself. Check your app to see if your model offers remote reset as a feature.

Why does the filter light come back on after just a few weeks?

A sensor fault or a defective filter cartridge is the most common cause. If you installed a new filter and reset the light correctly, but it comes back on within a month, the filter may not be seating properly in its housing, or the sensor may be malfunctioning. Remove and reinstall the filter to confirm it is seated fully, then contact Samsung support if the light persists.

Is there a way to turn off the filter light permanently?

No. The filter light is a safety feature designed to remind you when water quality may decline. Disabling it would mean you could forget to replace the filter and consume unfiltered water without knowing it. The light is meant to stay on until you reset it after installing a new filter.
