Your LG refrigerator ice maker was working, but now is not making ice? In this article, we will show you the most common LG Refrigerator Ice Maker Problems and how to test ice maker.
The most common LG refrigerator Ice Maker problems caused by temperature fluctuations (in the ice maker compartment), a faulty water inlet valve, a broken ice maker, a malfunctioned control board, or a faulty ice maker fan in the freezer section.
Let’s start with a simple diagnostic test you can run that may provide some insight on what that problem could be.
Please see Updates at the end of this post ” How To Troubleshoot Optical Sensors On The Ice Maker?”
Lg Refrigerator Ice Maker Troubleshooting
To run the ice maker test mode, first of all, pull the handle to open the ice room and remove the ice bucket.
There are two styles of LG refrigerator ice makers. On this first model, this is the power button.
Make sure it is turned on. The test button is underneath.
Here in the ice room put the towel to catch water or ice that may fall when you run the test mode.
Press and hold the button for about 3 seconds and the ice maker will begin to turn. If water or ice were to fall from the tray, the towel is there to catch it. The tray only holds about 4 or 5 oz of water.
Here’s a another style of ice maker on this model. There’s no power switch and no tray. Even though there’s no tray you should still place a towel below the ice maker before running the tests.
On this type of ice maker, there is a tiny hole on the left side. This is a Test Button. So press and hold the button for about 3 seconds until the arm starts to turn.

For the first 2 hours, the refrigerator has been plugged in, the ice maker test can only be run once. If you wish to run the test mode a second time, unplug the unit for about 30 seconds to reset the ice maker.
Why Lg Refrigerator Ice Maker Not Filling With Water
1.Water Filter – If during the test mode your ice maker didn’t fill with water, then check your
Without filter or when the filter installed not properly in the filter housing, water will not flow to the ice maker and water dispenser.
You just need slide filter into the housing, PUSH and TWIST to lock it.
If you recently changed the
With a new filter, water will flow more freely and when it reached ice maker it may create a splash.
Some amount of water will leak in the ice maker compartment to the very bottom and eventually will be on the floor.
If you have ball-type water tap behind the fridge, try to decrease incoming water pressure to the fridge by turning at 45 or less degrees. You need to play with it, to reach reasonable water pressure.
To do this adjustment, turn water tap to 45 degrees and let somebody will push water dispenser using big cup or something like that.
This way you will be able to decrease water pressure to desirable level.
Another problem can be when the ice maker leaking, its when ice maker dumping ice in the bucket, some ice cubes might stuck in the tray.
And when fresh water will fill ice maker, it actually will overfill and some amount of water will spill over the tray.

In this case, pull the ice maker out and clean inner side of the tray from the calcium build up.
2. Inlet Valve – When the water inlet valve failed, you will not have water as well. In order to check the inlet valve, you just need Multimeter.
But keep in mind, that LG fridges have 2 inlet valves. Main valve on the back of the fridge, secondary(for the ice maker) in the left door.
You need to check them both. Secondary valve getting water from the main valve. But from my experience, secondary valve causing most of the problem with the ice maker.
3. Water Hose – Behind your
4. Ice Maker – If ice maker failed to perform diagnostic test and you not able to run it, then most likely ice maker motor failed.
5. Control board – Every LG refrigerator has a control board. If the control board not sending power to the ice maker or one of the relays on the control board failed, then the ice maker will not run.
Important: If all components mentioned above in the article are ok and ice maker working ONLY when you press RESET button (ice maker should make a full turn and not making ice in automatic after that), then there is a problem with the main control board or optical sensors on the ice maker.
Make sure the control board fits the refrigerator model you have. !!!
why Is Ice maker not producing ice?
One of the reasons is malfunctioned ice maker fan, which is located in the freezer compartment.
This fan blows cold air into ice maker compartment and freezes up water.
If the temp in the ice maker compartment will be high than -12C, ice will not be produced.
In order to check if this fan is working, you need to apply a magnet to simulate a closed door ( see top side of the door where the magnet is located)
If you feel cold air coming out from the vents, fan is good.
This is a picture of back panel in the freezer compartment with evaporator and ice maker fans.

What should my LG freezer be set at to produce ice?
-2°F or -20°C is the recommended temperature setting for normal ice production. In order to adjust the temperature: Press the FREEZER button to cycle through the range of available settings and set it to the desired temperature.
How to Reset LG Refrigerator Ice Maker
In order to reset ice maker, unplug your refrigerator or turn breaker OFF for at least 30 sec. This procedure will reset the ice maker.

What Does Ice Plus Mean On My LG Refrigerator?
When all the ice in the LG refrigerator is used, it will take 2 hours to produce the next bunch of ice cubs. Some LG models are equipped with an “Ice Plus” feature. This feature just speeds up the freezing process and allows it to produce ice cubes 2 times faster.
How long does it take for LG fridge to make ice?
It depends. If you just bought and installed LG refrigerator then it may take about 24 hours. But if your refrigerator works more than 24 hours, in this case, every 2-3 hours ice maker will produce new ice cubes.
UPDATE: This is how ice maker works when releasing ice cubes and it’s normal to twist ice tray. For those who didn’t know that, it seems like the right side of the ice tray been jammed.
Update: How To Test Optical Sensor on The LG Ice Maker?
Optical sensor malfunctioning, one of the reasons why your ice maker may complete Harvest Cycle, but not working in Automatic Mode.
The first thing you need to do is to check optical sensors:
- Remove Ice Bin from the compartment
- Close the left door
- Wait for 3 minutes
- Freezer Door stays open
- Push Refrigerator button and Lock button at the same time
If ETY is shown on the display after the procedure above, Ice-detecting sensor is normal.
If FULL is shown on the display after the procedure above, Ice-detecting sensor is abnormal.
When it shows FULL with empty ice bin, something wrong with these sensors. As long as they are part of the ice maker, one of the options is to replace ice maker and see if it will solve the problem.

My ice maker does not operate. The test button on it does not make it work. I tried a new unit, same results. The ice dispenser motor does work. When I ‘trick’ the door switch with a magnet, I do not feel any air flow increase from the ice fan. The lights do go out when I do this operation. My only other thought is the main control board in the back. I did press the reset on it with no luck. Smart diagnostics showed no problems and no error code is indicated. Any help would be appreciated.
We have ice frozen in the ice maker trays. So it’s unable to make ice because the water isn’t going in the slots it’s spraying and splashing everywhere and freezing in the compartment. Please how do we get the frozen cubes out of the ice trays.
I have the same problem, water running down the outside of the fridge. Did you find a solution?
You may have calcium buildup word spraying the water into the tree compartment area also make sure your fridge is very level could be slightly forward or back which will have water possibly run over the sides and not produce your adequate ice
Read up on how to take the icemaker compartment out and clean out ice cube trays as best you can. Could use boiling water once that unit is out and unplugged or CLR and rinse it thoroughly there after. It’s not calcium buildup and not the level issue than the water line/ hose pressure from your residence can be turned down a little bit behind the fridge or under your floorboards so that’s not splattering water everywhere when in refill mode.
I replaced the ice maker and the waterline inlet valve assembly. I also changed the external water filter. The tray isn’t filling with water. What is the solution?
Pull your fridge out and shut off your water supply to the fridge. Then disconnect the connecter to your waterline to your fridge and have someone turn on that valve if you happen to have a valve behind the fridge you’ll know right away if you have appropriate pressure coming from your residence. If there is water pressure at the valve when you test it then reconnect waterline try unplugging your fridge for 30 seconds and plug it back in to reset your ice cube maker. Thirdly there are valves that turn on and off the valve to the ice maker behind the fridge, you can look at the LG website if you want to do it yourself to test or call a LG / refrigerator repair company. And you can also check the optical sensors that may be just dirty or need to be replaced and there’s a simple self testing of those as well.if covered with calcium spray, It will think that the ice bucket is full and water won’t be released to the water/ ice tray.
Tray when goes upside down it catches the upper shell and stops the tray from completing the cycle so is throat stretched out or is there away adjust it it doesn’t catch the upper shell
I have the same exact issue! Haven’t figured it out yet though…was thinking to file down the upper shell or the tray itself. YOu have any luck?
Not sure exactly what you’re watching when you do the reset /test button. The ice cube tray should flip over on certain models and then it will look looks it’s binding on the right side /give a twist so it looks like it’s jamming, but in actuality it has to twist the poly/ plastic tray to release the ice cubes. That is perfectly normal
This afternoon the ice in our ice maker started melting and tonight we noticed everything in our freezer is almost thawed. The refrigerator seems cool, but not cold. Any ideas of what is going wrong and suggestions for what we can try? Our fridge is 2 1/2 years old.
There is a known problem with the compressors on LG fridges. We had an issue last July of 2021. The replacement compressor is under warranty but not the labor to install it. We spent $600 but you may be able to find a tech who will do it for less.

Don’t know but our LG fridge is doing the exact same thing so if you find out the problem I would appreciate it if you could let me know. Thanks.
I did turn down the temp on fridge and freezer and food seems to be more frozen now.
The metal arm that must go up to reset the ice maker sometimes has drops of frozen water on the end, therefore inhibiting the are from rising with a no ice.
We have a new big LG model that produces white powder in the ice. The fridge is about 3 months old. What’s going on? We spent over $3k on this. Thank you!
Hi
My ice maker tray turns to dump ice, makes a loud clicking noise like it’s trying to get back to the right side up position then gets stuck upside down. When I press reset or on/off it makes this same loud noise and gets stuck. Any suggestions/help would be great!
Have the same problem, was going to cut the corner where the trlay hits ?
Model LFX25961AL/01 ice tray not filling with water and sounds like an intermittent growling noise coming from the housing. Any ideas?
LG refrigerator ice maker not making ice always cross tray on it filling up five of the seven what could be the problem changed the pump the filter and new ice maker and still doing the same thing any help thank you
Had my LG Fridge for about 5 years now and its never reliably made ice. It seems to work and not work at totally random times … sometimes it’s fine for weeks, filling up the bucket over and over and then its cactus for months on end. Just stops dispensing ice. Ice is in the tray part ready to go – just never cycles the fingers to rotate and push the ice out. At 1am last night (or this morning if you prefer) I heard ice drop into the ice bucket … waited a few seconds – could hear the water line turn on to fill the tray back up again. Now this was after 6 months of ZERO ice production. It continued to work fine for about 6 more cycles of making ice today then it just magically stopped again with about 30 bits of ice collected in the bottom of the ice bucket … it’s not even 1/4 filled. The ice maker tray is sitting there, ice cubes frozen and ready to go, but it never cycles the fingers to rotate and push the ice out, nor does it heat up to begin to dislodge them. If I press and hold the button on the actual ice maker (there is only one button on it) the fingers will go round – then get forever stuck on the ice and not dislodge them until I pour some boiling water on them to help dislodge them.
For an expensive fridge – it’s disappointing that the icemaker has been a complete piece of garbage 🙁
My LG thinq makes ice but does not dispense the ice unless I press the reset button. What could be the problem? Any suggestions?
Ice maker is making ice but is no noise and does not dispense any ice when I push to do so
when dispensing ice it sprays everywhere. Can it be fixed so the
ice drops straight into the glass an doesn’t go everywhere?
All of a sudden it takes 6+ hours to cycle through And drop ice into the bucket. It feels as though the ice is formed and solid however just doesn’t drop. The ice tray does fill up with water right after the 7 cubes drop. I went from a full compartment of ice to maybe 20 cubes a day.
Check the position of the ejector arm both right after it ejects ice and then after about 3-4 hours. We had a problem where the ice tray heater burnt out and the ejector arm would take a long time to eject ice frozen to the tray.
So my LG is filling the ice cube trays with just a little too much water. It makes for a large chunk of ice and makes a horrible clunking noise as it tries and fails to dislodge the cubes. How can i adjust this so it doesn’t fill up with too much water?
The issue on my LG Ice maker is that the fridge was level, but the icemaker was not and was leaning forwards a bit causing ice to not be level in the tray. The water then froze at too high towards the front part of the tray and caused the the rotating Ice Remover claws to not be able to rotate due to them getting caught on the frozen Ice cubes due to being elevated so much that the water in the trays was touching the claws and freezing the claws in place. I simply removed the existing ice using a small screwdriver and then leveled the ice maker by using a couple wedges. Reset it and all has been good.
I have an LG fridge model LMXS30776S / 03
I got an E 15 error code and originally I could open the ice maker door and the code would go away and the ice maker would operate when I pressed the test button, it would refill once and never dump the ice it made.
Fast forward to now and the code still pops up and it won’t reset unless I unplug the fridge. But now the ice maker won’t operate at all when I press the test button.
I saw at LG’s site that with that code it’s the fan or the sensor that isn’t working properly.
I used a magnet to simulate the door shutting and the fan blows air out of one of the vents, and one vent has nothing blowing out (maybe a return vent?) This test won’t work at all when the code is lit on the operating panel.
After reading the article, it seems like the ice maker or the control board is the problem but before I take the gamble and buy either, I wanted to see if anyone had any other thoughts before I proceed and replace one or the other.
If the ice maker fan is working and you can feel it, then the problem can be with the wiring located on the left top door hinge. I can not give you the exact procedure on how to check that. But you need to check wiring for continuity from the freezer where the fan is located to the inner wiring of the left door.
Thank you I will check it.
My ice maker makes ice fine but the they continue to stick (freeze) together. After a few knocks on the ice container…all’s fine till the next attempt.
