The Ice Maker Switch Is Usually Inside the Freezer
Most Samsung refrigerators have an ice maker power switch located on the inside wall of the freezer compartment, typically on the right or left side near the top. Look for a small lever or toggle switch—it may be labeled "Ice Maker" or have an icon showing ice cubes. Push or flip it to the "On" position. If you see the switch in the "Off" position (often marked with a line or circle), that is why your ice maker is not running.
Some Samsung models use a different design: the switch may be a push-button on the front of the ice maker itself, which hangs from the freezer ceiling or sits in a corner. Check your refrigerator's manual or the inside of the freezer door for a diagram showing exactly where your model's switch is located.
Once you turn the switch on, listen for a humming sound within a few seconds. That sound means the ice maker is working. It typically takes 24 hours for the first batch of ice to form and drop into the bin below.
Key Takeaways
- The ice maker power switch is almost always inside the freezer, usually on the side wall near the top, and looks like a small lever or toggle.
- Make sure the switch is in the "On" position; many ice makers are accidentally left in the "Off" position after cleaning or restocking the freezer.
- After turning the switch on, you should hear a humming sound within seconds, which means the ice maker is receiving power.
- Your first batch of ice typically takes 24 hours to form, so do not assume the ice maker is broken if no ice appears when ready.
- If the switch is on but you hear no sound and no ice forms after 24 hours, the water supply line may be frozen, disconnected, or the water inlet valve may need service.
Check That Water Is Reaching the Ice Maker
Even with the switch on, the ice maker needs a steady water supply to work. Samsung refrigerators with ice makers have a water line running from your home's water supply to the back of the unit. If that line is kinked, frozen, or disconnected, no ice will form no matter how long you wait.
Walk behind or beside your refrigerator and look at the water line—it is usually a thin plastic or copper tube. Make sure it is not bent sharply or pinched. If the line looks fine, trace it to where it connects at the back of the refrigerator. The connection should be tight; if water is dripping or pooling, tighten the fitting by hand or with a wrench, or call a service technician.
In very cold garages or basements, the water line itself can freeze solid. If you live in a cold climate and your ice maker suddenly stops working in winter, this is a common cause. Wrapping the exposed water line with pipe insulation or heat tape can prevent this.
Make Sure the Ice Bin Is Seated Correctly
Samsung ice makers have a safety switch that stops the machine if the ice bin is not pushed all the way in. If the bin is loose, tilted, or sitting at an angle, the ice maker will not run even though the power switch is on.
Remove the ice bin completely and look inside the freezer compartment. You should see a small arm or lever on the side or back wall where the bin slides in. This is the sensor that detects whether the bin is in place. Slide the bin back in firmly until you hear or feel it click or seat fully. The arm should rest against the bin without being forced.
If the bin is cracked or warped, it may not sit flush, and the sensor will not register it as closed. In that case, you will need a replacement bin. Samsung sells these as separate parts, and you can order one through their website or a parts retailer using your refrigerator's model number.
Verify the Water Inlet Valve Is Open
Behind your refrigerator, where the water line connects, there is usually a small shut-off valve. This valve controls whether water flows into the ice maker at all. If someone turned this valve off—perhaps during cleaning or a repair—the ice maker will not work.
Locate the valve at the point where the water line enters the refrigerator. It typically looks like a small knob or lever. Turn it clockwise (to the right) until it stops; this is the "On" position. Do not force it—it should turn smoothly. If the valve is already open and water is not flowing, the valve itself may be stuck or broken, and you will need a technician to replace it.
If you are not comfortable working behind the refrigerator or if you cannot locate the valve, take a photo of the back of your unit and contact Samsung support or a local appliance repair service. They can confirm the valve position and check the water line for you.
Reset the Ice Maker If It Is Still Not Working
If the switch is on, the water line looks clear, the bin is seated, and you still hear no sound from the ice maker after 24 hours, try a reset. Unplug the refrigerator from the wall outlet for 5 to 10 minutes, then plug it back in. This clears the ice maker's control board and often restarts the cycle.
Some Samsung models also have a dedicated reset button on the ice maker itself. Check inside the freezer near the ice maker unit for a small button labeled "Reset" or with a circular icon. Press and hold it for 3 to 5 seconds. You may hear a click or see the ice maker arm move slightly, which means the reset worked.
After a reset, wait another 24 hours before deciding the ice maker is not working. The system needs time to fill the mold and freeze the water.
When to Call a Service Technician
If you have turned on the switch, confirmed the water line is connected and not frozen, seated the ice bin correctly, and waited 24 hours with no ice forming, the problem is likely inside the refrigerator. Common causes include a frozen water inlet valve, a broken water pump, or a faulty ice maker motor—all of which require professional repair.
You should also call a technician if you see water pooling under or behind the refrigerator, if the ice maker is making loud grinding or rattling noises, or if the ice tastes or smells unusual. These signs point to internal problems that are not safe or practical to fix yourself.
Samsung offers phone support and can connect you with authorized repair centers in your area. You can also search for local appliance repair shops that service Samsung refrigerators. Bring your refrigerator's model number (found on a sticker inside the fridge or freezer) when you call.
Frequently Asked Questions
How long does it take for ice to appear after I turn on the ice maker?
Your first batch of ice typically takes 24 hours to form and drop into the bin. After that, the ice maker usually produces a new batch every 90 minutes to 2 hours, depending on your freezer temperature and how much ice you use. If no ice appears after 24 hours, check that the water line is connected and the bin is seated.
Why is my ice maker on but not making ice?
The most common reasons are a frozen or kinked water line, a water inlet valve that is closed or stuck, or an ice bin that is not seated properly. Less often, the water pump inside the refrigerator has failed. Start by checking the water line and bin, then verify the shut-off valve behind the fridge is open.
Can I turn off the ice maker without unplugging the whole refrigerator?
Yes. Use the power switch inside the freezer to turn the ice maker off. This stops ice production without affecting the refrigerator's cooling. The switch is designed for this—you do not need to unplug anything.
What does it mean if the ice maker is humming but no ice is forming?
A humming sound means the ice maker is receiving power, but water is not reaching it. Check that the water line is not kinked or frozen, and verify the shut-off valve behind the refrigerator is fully open. If both are fine, the water inlet valve or pump inside the refrigerator may be faulty and will need professional service.
Is it normal for the ice maker to be loud when it first turns on?
A brief humming or clicking sound when the ice maker starts is normal. However, loud grinding, rattling, or continuous noise is not. If the noise is very loud or does not stop after a few seconds, turn off the ice maker and contact a technician, as this can indicate a mechanical problem.
