Samsung Ice Maker Keeps Freezing Up. How to Fix?

If your Samsung refrigerator is experiencing ice maker problems where it continually freezes up, you can take a few troubleshooting steps to get it working properly again. An ice maker freezing up can prevent ice production, lead to overflow and leakage, or even damage components. Identifying the cause is key to correcting the issue. Here is how to troubleshoot a Samsung ice maker that keeps freezing up and simple repair tips to fix it.

Samsung Ice Maker Keeps Freezing Up

Causes of Ice Maker Freeze-Up Issues

There are several common reasons a Samsung ice maker may freeze up, including:

– Low freezer temperature – A thermostat set too cold can freeze water before cubes form.

– Ice maker arm stuck – If the detected arm stays down, the unit thinks the bin is full and won’t cycle.

– Faulty water inlet valve – Leaking or dripping valve can overflow the mould, causing freeze-up.

– Drainage problems – Clogged drain tube prevents water from exiting, leading to overflow.

– Ice cubes stuck – Cubes wedged in the tray prevent ejection, leading to ice buildup.

– Bad thermostat – Ice may partially melt and refreeze if the freezer won’t maintain proper 0°F temp.

– Scale build-up – Mineral deposits in the water line can cause ice to overfill.

– Control board issues – Defective control boards can fail to shut off ice production.

– Frozen water line – External plastic water lines that freeze cause insufficient water supply.

– Bad ejector gear – If the gear motor fails, ice won’t eject and will build up.

You can zero in on the proper solution by identifying which issues are causing excess ice.

1. Check Freezer Temperature

The first step is verifying your Samsung refrigerator’s freezer temperature. The optimal temp for proper ice creation is 0°F. If the freezer is set colder than this, such as -5°F or below, the water may start freezing before the mould can form into cubes. This causes a solid chunk of ice to accumulate rapidly.

Check your owner’s manual for how to access freezer temp settings, typically through the control panel or touchscreen. Adjust the setting up closer to 0°F and monitor ice maker operation over the next 24 hours. This may allow cubes to eject normally without freezing up.

2. Ensure Ice Maker Arm is Lowered

Another common cause of ice maker freeze-up is the detected arm getting stuck in the up position. This arm automatically lifts up when the ice bin is full. However, if it fails to lower when the bin empties, the ice maker will stop producing ice. This allows water to back up and overflow, becoming one solid block of ice.

Carefully inspect the arm to confirm it can move up and down freely. Press it to ensure it returns to its lowered position across the ice tray. If stuck, apply firm pressure or use a wooden spoon handle to lower it manually. This will reset the Detection system, and ice production should resume.

3. Replace the Defective Water Inlet Valve

A major culprit for Samsung ice maker freezing over is a leaking or continuously dripping water inlet valve. This valve controls the water supply flow to the unit. It may allow excess water to enter and overflow the compartment if worn out.

Turn off the ice maker, unplug the fridge or shut off the household water supply. Remove the access panel and inspect the valve visually. Look for cracks, corrosion or obvious drips/leaks. If faulty, unscrew the inlet valve and install a new OEM replacement valve. Turn the water back on and test the operation to confirm proper water flow/shutoff before replacing the cover.

4. Clear Clogged Drainage Line

The ice maker relies on a small drainage tube to remove melted water as cubes are ejected. If this plastic drain line gets clogged or kinked, water can back up and cause ice overflow.

Carefully remove the back panel and inspect the drain tube. Clear any ice or debris buildup from the line. Make sure it’s angled down properly and not kinked/obstructed. If needed, detach from the ice maker, use a hair dryer to thaw, and reattach to the fitting—test by pouring a small amount of warm water into the unit while running.

5. Remove Stuck Ice Cubes

Another simple fix is to clear any stuck ice from the ejector arms and mould trays. Cubes wedged in the ice maker prevent the mechanism from turning properly to dispense new batches. This creates a domino effect of constant freezing and blockage.

Use a plastic spoon to gently free any stubborn cubes stuck in the trays or chute. Don’t use anything metal that could damage the plastic mould parts. Verify ice can fully eject into the bin. You may need to power off the ice maker for 1-2 hours to melt cubes and fully clear any jam.

6. Replace Bad Thermostat

The thermostat may be defective if your Samsung freezer struggles to maintain a steady 0°F temperature. This component monitors temps and triggers refrigerant flow to cool as needed. If the thermostat is broken, icy fluctuations occur, leading to melting and refreezing.

Purchase a new thermostat that matches your Samsung fridge model. Carefully remove the back panel and locate the thermostat. Unplug the connectors, unscrew and replace them with the new part. Reconnect wiring properly and test freezer temps over 24 hours. Steady 0°F means the thermostat is working again.

7. Remove the Ice Maker Scale Buildup

Hard water containing high mineral content can leave scale deposits inside the ice maker over time. This buildup can restrict water flow, causing overflow and freezing issues.

Vinegar is the best home remedy for removing scale deposits. Power off the ice maker, fill mould trays with plain white vinegar and let stand for 1-2 hours. Rinse with clean water several times to clear the vinegar smell. Replace any plastic tubing if severely clogged with the scale.

8. Replace the Defective Control Board

If no mechanical issues are found, a faulty control board computer may be improperly signalling the ice maker, leading to constant freezing up. Control boards manage timing and temperature sensors.

Unplug the fridge to fully power down and give the computer a hard reset first. If the problem repeats, the control board likely needs professional replacement. The part number is typically located on the board itself. Have an appliance technician source and install the correct new Samsung control board.

9. Insulate the External Water Line

For Samsung models with water lines running externally through the cabinet, cold weather can cause freezing issues. Insulating the water lines helps prevent supply interruptions leading to ice maker malfunctions.

Buy foam tubing insulation with adhesive backing made for refrigerant lines. Wrap any exposed plastic tubing that runs outside the insulated cabinet. This protects lines from freezing temps. Also, replace plastic lines with newer fos-free reinforced tubing.

10. Replace Ejector Gear Motor

If none of the above fixes your ice maker freeze-up problem, the internal ejector gear motor may be faulty. This small motor powers the release of cubes into the bin. Burnout can cause ice to get stuck and overflow the unit.

Have an appliance repair technician verify the ejector gear motor is defective using multi-meter testing for continuity. They can then install a replacement Samsung ejector gear motor and test for proper ice release. Make sure to clean all ice buildup before reinstalling panels.

Preventing Future Samsung Ice Maker Freeze Up

Follow these tips to minimize recurring ice maker freeze-up issues:

– Set freezer temperature to 0°F consistently. Monitor temps weekly.
– Change filters regularly for clean water flow.
– Keep the bin emptied to allow the arm to lower properly.
– Clean out mould trays every 3 months to prevent stuck ice.
– Avoid overfilling the bin with bags of ice that obstruct detect arm.
– Have a plumber install an inline water filter if you have hard water problems.
– Insulate any external water lines on the fridge.
– Listen for the water valve hissing/leaking and replace it ASAP if needed.

Following proper maintenance and temperature regulation will optimize Samsung ice maker operation. But freezing issues typically indicate a mechanical defect or part failure needing repair. Catching problems early prevents permanent damage and expensive replacement of the entire ice maker assembly.

FAQs About Fixing Samsung Ice Maker Freeze Up

1. Why does my Samsung ice maker freeze up right after changing the filter?

Freezing issues after a filter change are usually due to air bubbles in the water line. Let the dispenser run for 3-5 minutes to prime the line and clear air pockets fully. The ice maker will then function normally.

2. Can low water pressure cause the Samsung ice maker freezing?

Yes, if your home’s water pressure drops below 30 psi, it can restrict the water supply to the ice maker and cause freezing and malfunctions. Have a plumber confirm adequate pressure.

3. Does turning off the ice maker stop water from freezing?

Unfortunately, the freezing occurs in the internal ice maker unit, not the dispenser. You must identify the root cause, such as temperature, stuck ice or leaks. Simply powering off will not stop internal freeze-up issues.

4. Why is my Samsung ice maker making large slabs of ice?

Oversized ice slabs are usually caused by mineral scale buildup or cold temps. Remove the scale with vinegar and increase the temperature closer to 0°F to allow cubes to eject properly.

5. How do I know if my ice maker has frozen permanently?

The unit will likely require complete replacement if internal parts like trays and ejector gears are completely encased in solid ice and unmoving. Try powering off the fridge for several hours to thaw fully.

Troubleshooting and fixing an overflowing, freezing Samsung ice maker will require patience. Work through each possible cause methodically to pinpoint the issue. In severe cases of ice buildup, allow the unit to thaw fully before attempting repair. With attention and care, your Samsung ice maker will return to producing crisp, clear ice cubes in no time.
