If you are experiencing LG refrigerator ice maker problems, then, this article is for you.
In this article, we will give you a comprehensive guide to help you in troubleshooting and fixing all problems you might experience with your LG ice maker.
So, let’s get started.
LG refrigerator ice maker problems
For easier troubleshooting, we will fix the ice maker depending on how the ice maker is behaving.
LG refrigerator ice maker not working / LG refrigerator ice maker won’t work
To kick us off, is the ice maker turned on?
On your display, locate the Ice On icon and confirm that you have your ice maker turned on.
Also, some models have a power button on the side of the ice maker.
To access this button, you will need to first remove the ice bin.
Now, on the side of your ice maker, you should see an on/off button as shown below:
If it is off, be sure to turn it on.
Does your refrigerator make loud humming/buzzing sounds?
If yes, it is likely that your ice maker is not connected to a water line.
And if it is, it could be that the water line is kinked or damaged to an extent it is not delivering water to the ice maker.
So, inspect the water line and straighten out any kinks that may be present.
If the water line is damaged, be sure to get an OEM LG water line replacement.
Speaking of water line, have you checked to see if the water valve is turned on?
Finally, check the feeler arm – confirm that it is not pushed up and that it can move freely.
If it were pushed up, the ice maker would stop producing ice entirely.
So, if it is stuck in the up position, be sure to pull it down and confirm that it is moving freely.
Tip: once you have turned on the ice maker, give it at least 24 hours for it to resume normal ice production.

Some of the troubleshooting steps for an ice maker that is not producing ice are similar to the ones we have just covered above on LG refrigerator ice maker not working.
So, be sure to start with the above steps before proceeding with the ones below.
What is your freezer temperature?
Tip: you can use a thermometer to measure the temp inside your freezer.
In order for ice to be produced, a minimum temperature of at least 19⁰F is required.
Nonetheless, LG recommends a temperature of -4⁰F for normal ice production. So, if your freezer’s temperature is above this, be sure to set it to a colder setting.
Reset the ice maker
Before you reset the ice maker, first remove the ice bin and follow this by putting a towel in place of the ice bin.
The towel will soak any water and hold any ice cubes that may fall from the ice maker.
Now, there are two types of LG ice makers and each has its own reset procedure. Here are the steps to reset each:
- For models that have a Twist/Flex Tray icemaker, press and hold the test/fill button at the bottom of the ice maker until the ice maker starts to turn.
- For models that have a Heater/Custom Cube™ ice maker, insert a paper clip into the small hole on the side of the ice maker as shown:
Now, to engage the test button, press and hold the clip until the ice maker starts to run.
LG refrigerator ice maker not freezing
The troubleshooting steps for this are similar to the ones we have just covered above on LG refrigerator ice maker not making ice.
Therefore, check them out to fix your ice maker that is not freezing.
LG refrigerator ice maker not making enough ice
Start by checking the set temperature.
A temperature of below 19⁰F will produce ice but not enough.
LG recommends a freezer temperature of at least -4⁰F for ice production. So, be sure to set the freezer temp within this range.
By the way, have you recently emptied the ice bin?
You see, once the ice bin is empty, it will take up to 90 minutes before additional ice is available and around 24 hours for the bin to refill with ice.
So, if your refrigerator is working within this range, then it is pretty normal and you shouldn’t be worried.
Have you changed the water filter recently?
With time, the water filter will become clogged with particles. In turn, this would result in less water flowing to the ice maker hence little ice production.
As such, LG recommends that you change the water filter every six months.
So, if you have not changed the water filter recently, you will need to get a genuine filter from LG.
Using a generic filter will void the warranty as LG does not cover it.
Fortunately, you can order an OEM LG water filter from their Amazon store.
How often are you opening the refrigerator door(s)?
If you are frequently opening them, the cold air inside the unit will escape and this will prevent your unit from maintaining the temperature it requires to produce ice.
So, be sure to only open the refrigerator only when necessary.
Is your display blinking 67?
If your unit is blinking this code, it means that the doors are not closing fully.
Consequently, this will lower the internal temps hence little amount of ice will be produced.
So, start by confirming that there is no foodstuff preventing the door from fully closing.
Next, using a mild detergent and a moist cloth, wipe the door seals to clean them and then let the unit sit for 24 hours.
Still, if your refrigerator does not resume normal ice production, it means that the door seals are damaged.
Consequently, you will need to get LG OEM door gasket/seal replacement.
Before your gasket replacement arrives, you can use the express freeze or ice plus functions.
Selecting any of these functions will result in the compressor running continuously for three hours thereby increasing the amount of cold air inside the freezer compartment.
In turn, this will translate to more ice production.
Note: before you activate these functions, first set the freezer temperature to 0⁰F or colder.
Check the water valve and water pressure
It could be that the water pressure is not enough to fill the ice maker within the required time.
When using a water filter, you will need a water pressure of between 43 and 121 psi.
On the other hand, if you are not using a water filter, you will require a water pressure of between 21 and 121 psi.
So, confirm that the water valve is fully open and that the pressure is within the above range.
Also, if your home uses a reverse osmosis system, it might reduce the water pressure going to your refrigerator.
The easiest way to fix this is by connecting your refrigerator to a water line that does not use the reverse osmosis system.
LG refrigerator ice maker problems – repairing further faults
LG refrigerator ice maker not dumping ice / LG refrigerator ice maker not dropping ice / LG refrigerator ice maker not dispensing ice / LG refrigerator ice maker won’t dump / LG refrigerator ice maker won’t dispense ice
First, check and confirm that the ice bin has ice. If it doesn’t, follow the troubleshooting steps above on LG refrigerator ice maker not making ice.
On the other hand, if the ice bin has ice, follow the steps below…
Is child/control lock turned on?
If it is, the lock indicator on your display will be turned on.
To turn it off, simply press the lock function.
Next, you will need to inspect the ice cubes in the ice bin and confirm that they have not clumped together.
You see, when these ice cubes clump together, they will become too thick to go through the ice chute.
So, if there are any ice clumps, be sure to remove them.
Inspect the chute for any clogs and if there are, use a warm rag to melt the ice clogs and then dry the chute using a dry rag.
It could be that the ice passage is clogged with ice cubes.
Consequently, you will need to unblock it.
To do this, first put a dry towel under the ice dispenser.
Now, while pressing the ice dispenser lever, pour some warm water into the ice chute beneath the ice bin.
Other than that, pull out the ice bin and inspect if the auger motor is frozen.
If it is frozen, you will need to thaw it.
To do this, place a warm rag on the ice and then dry out the auger motor using a dry rag.
LG refrigerator ice maker not getting water
Start by confirming that the water valve is open.
Next, inspect the water line for any kinks and if there are any, be sure to straighten them out.
Have you replaced the water filter of late?
You see, the water filter requires to be replaced every three to six months. This will depend on the water quality in your city and the size of your household.
So, if you have not replaced the water filter recently, it could be clogged hence no water will travel to the ice maker.
Bearing that in mind, be sure to get an OEM LG refrigerator water filter replacement.
LG refrigerator ice maker not filling with water / LG refrigerator ice maker won’t fill with water
In most cases, this is usually a case of low water pressure more so if it is a new refrigerator.
Typically, LG recommends a water pressure of between 43 and 121 psi on models that have a water filter.
As for models that do not have a water filter, LG recommends a pressure of between 21 and 121 psi.
So, be sure to measure the water pressure in your water line and ensure that it is within the above range.
Again, have you changed the water filter of late?
If you haven’t, then, it is likely that this is the culprit.
You see, with time, the water filter will get clogged with particles. In turn, this will result in the amount of water flowing through the filter reducing.
So, if you have not changed the filter within the past six months, you will need to get a replacement filter for your model.
LG refrigerator ice maker overflows with water
In most cases, this is usually as a result of a high water pressure in your home.
Usually, LG recommends a maximum pressure of 121 psi.
So, test your pressure and confirm that it does not go beyond this.
A quick fix to this can be by partially closing the water valve to reduce the water pressure.
However, the better workaround is to get a refrigerator water pressure regulator. They are very cheap as most are usually under 20 bucks by the way.
We recommend you get the Hydronix water pressure regulator that will regulate your pressure to 60 psi which is within the optimal range.
Is your refrigerator properly leveled?
At other times, it could be that you simply have your refrigerator not leveled as it should.
This is more so if you have a brand new LG refrigerator whose ice maker is overflowing with water.
Bearing this in mind, check out LG’s refrigerator leveling instructions and follow them to properly level your model.
Nonetheless, there are other ice maker model-specific steps as we shall see below.
Twist-N-Serve/Flex Tray ice maker overflows with water
For this model, it is just a case of improper leveling or high water pressure.
So, check out the above steps.
Early Twist/Flex Tray ice maker overflows with water
In addition to a high water pressure, it could also be that the flow sensor that determines the amount of water flowing to the ice maker is malfunctioning.
When this is the case, the ice maker will revert to a timed fill.
Heater/Custom Cube™ ice maker overflows with water
This is normally as a result of the size selector being set too high.
Recall that the size selector is used to accommodate the water pressure.
Note: with each increase in size, the size selector will add half a second to the amount of time the fill tube remains open.
So, you will need to select a lower size to prevent overflowing.
LG refrigerator ice maker freezing up
Typically, this is caused by an overflowing ice maker as the water will freeze over.
Therefore, make sure that you follow the above steps on LG refrigerator ice maker overflowing with water to fix the freezing up.
Tip: you will need to defrost the ice maker before you test for water overflow issues.
LG refrigerator ice maker leaking
When it comes to a leaking ice maker, most of the troubleshooting steps are similar to those of an overflowing ice maker that we have just covered above.
So, be sure to check them out.
However, if your ice maker is leaking from the bottom, then, it is likely that one or more of the ice trays is cracked.
Unfortunately, the only remedy to this is to replace the entire ice maker.
Again, be sure to get OEM parts from LG such as the Aeq72910411 ice maker.
LG refrigerator ice maker water line leaking
First, check and confirm that you have properly connected your water line.
If you have not properly connected it, water will leak from one of the ends of the water line.
In other words, confirm that the water line is not loose. You can confirm this by tagging it a little bit.
If it feels loose, be sure to tighten it up.
This is mostly the case if your water line is leaking in your brand new refrigerator.
Other times, it could be that the water line is damaged – perhaps it has a tear or a tiny hole.
This is mostly the case if the water line seems to be leaking from the middle of the line.
If it is indeed damaged, you will need to get a replacement water line.
Luckily, LG offers OEM water line replacement that you can easily order on their Amazon store.
LG refrigerator ice maker not working after changing water filter
Before replacing the water filter, you turned the water valve off.
So, did you remember to turn it on?
If no, be sure to turn it on.
Have you let the new water filter lock fully in place?
As you turn the water filter clockwise, you should hear a ‘click’ indicating that the filter has fully locked in place.
If you do not hear this click, then, you have not fully inserted your water filter.
Bearing that in mind, take out the filter again and re-insert it. turn it clockwise till you hear a click indicating that it has locked into place.
Did you purchase the right water filter for your model?
Water filters normally have a model number inscribed near the top.
When purchasing a new water filter, you will want to confirm that the model number of the replacement filter matches that of the one you just replaced.
LG refrigerator ice maker not turning
Start by resetting your ice maker.
For better results, unplug the refrigerator for around five minutes. This allows it to clear all static charges from the control board that might be causing the malfunction.
Next, reset the ice maker using the test button (refer to the steps under LG refrigerator ice maker not making ice that we have covered above).
Does the ice maker turn during the reset procedure?
If yes, then, your ice maker should now be fixed.
On the other hand, if it isn’t, it means that your control board is acting up. Consequently, you will need to get an OEM LG control board replacement.
LG refrigerator ice maker problems – more solutions
LG refrigerator ice maker making noise
Is the ice maker making a humming/buzzing noise?
If yes, your ice maker is experiencing water supply issues – the ice maker tries to fill with water but no water is coming in.
First, confirm that the refrigerator is connected to a water valve and that the valve is turned on.
Next, you will want to check along the water line for any kinks. If there are any, be sure to straighten them out.
Is the ice maker making a knocking noise?
If yes, then, the next part is for you.
LG refrigerator ice maker won’t turn off
If your ice maker is continuously dispensing ice, first, turn on the control lock by tapping on the lock function on your display.
This should turn off the dispensing function and give you leeway to fix the main issue.
Now, chances are that the dispenser lever is stuck and you will need to unclog it.
To do this, first pull out the lever and then push it in gently. Repeat this several times
Next, push the lever left to right repeating this several times.
Doing so will fix your stuck dispenser lever.
Tip: don’t dispense ice into a glass with liquid more so sugary drinks as the drinks will splash on the lever. The sticky residue from sugary drinks will result in the lever clogging. Instead, always dispense the ice into an empty glass and then add your favorite drink.
You can now turn off the control lock and see if your dispenser turns off.
If it doesn’t, it means that the dispenser switch is faulty. In this case, the only fix is to get a replacement OEM LG refrigerator dispenser switch.

LG refrigerator ice maker knocking noise
Mostly, you will hear this noise when the ice bin is empty.
It is usually the sound of ice falling into the ice bin.
This knocking noise may be louder in the craft ice maker as craft ice is larger (and heavier) than regular ice cubes.
So, don’t be worried as the noise is pretty normal.
