Why My LG Refrigerator Ice Maker Freezing Up? – Top 6 Causes

LG Refrigerator Ice Maker keeps freezing up when you least expect it. LG Refrigerator Ice Maker works wonderfully, and all you have to do is to let the machine keep on running at its optimum temperature. However, as time goes by, there are chances that the unit may start showing signs of having problems. You may face that the ice maker freezes up, and the ice cubes do not drop

So, before it gets too late, here are some simple and easy tips that you should follow to ensure that your LG Refrigerator Ice Maker remains functional for a long time to come.

The LG fridge ice maker can freeze up due to many reasons such as Freezer temperature is too low, faulty water filter, incorrect water pressure, faulty water line, etc.

What Causes LG Refrigerator Ice Maker Freezing Up? Troubleshooting and Diagnosis

LG Refrigerator Ice Maker Freezing Up

Let’s look at the possible causes and solutions for it.

Freezer Temperature Is Too Cold

What causes a Freezer Temperature Is Too Cold? When the fridge temperature drops into the 25-degree range, and there are no alerts to let you know it, you need to take action. If the freezer temperature is too low, normally, ice will not thaw out quickly enough and could cause the frozen food items to burst. Turning the freezer temperature up too high can also cause a Freezer Drying Up Problem.

When you notice that the Freezer Temperature Is Too Cold, one of the first things you should do is increase the freezer’s temperature to the optimum temperature. In the USA, we recommend that freezer temperature be 0° F or -18° C for the rest of the world.

Fill Tube and Water Supply Line Frozen

The water supply line and fill tube’s main function is to supply water to the ice maker so that it can make ice cubes. The fill tube in your LG refrigerator transfers water from the water supply line to the ice maker.

You need to inspect the fill tube and see if it’s frozen or not. To check it, you may need to remove the LG icemaker and see for any frozen signs.

If you confirm that the fill tube is frozen, you need to melt the excess ice by pouring hot water over the tube using a turkey blaster.

You can also remove the fill tube and put it in the sink, and give it some time for all ice to melt. To remove it, you need to unscrew a few screws behind the fridge and remove the water supply line. Once all ice is melted, place it back in the refrigerator.

Many people may suggest using a hairdryer to remove excess ice, But you need to be very careful as the water can drip into the wire, and you may get an electric shock. We do not recommend exposing the supply line to a long period of heat as it may damage the parts of the refrigerator.

Water Filter Is Clogged

LG refrigerator ice makers are very reliable but sometimes they can experience minor issues such as a clogged water filter.

A clogged water filter can cause incorrect water pressure. It will result in the LG Refrigerator Ice Maker Freezing Up problem.

To find out if the filter is really clogged, you can try to pour a glass of water into it while it is still inside and see if you get some condensation. If you do, then this probably indicates that the filter is full and requires to be replaced. Many repair technicians can easily replace the filter on your LG refrigerator so that you do not have to worry about having freezing water inside your refrigerator all the time.

Incorrect Water Pressure

Please check the water pressure of the supply line going into the refrigerator. If you observe that water pressure is too high or too low, you may get the LG Refrigerator Ice Maker Freezing Up.

You should make sure that water pressure doesn’t exceed 120 PSI as the excess water may get freeze inside the ice maker, and you will get the icemaker freezing problem.

Incorrect Water Line Positioning

Sometimes during installation or moving the refrigerator to different locations, the water is pushed too far into the water valve. Due to distance, it may result in a splashback effect, and water can sip into the freezer and freezes there.

Faulty Water Inlet Valve

The main function of the water valve is to control the water flow coming into the LG Icemaker. You can locate it behind the LG fridge, and it is usually near the back access panel. Many a time, the water valve becomes faulty and causes further issues.

Take a multimeter and use it to do a continuity test of the water valve. If it fails the test, then replace the water valve.

Sometimes water valve can also get clogged due to the minerals and small sand particles, especially if you use hard water for a very long time. You need to remove the water inlet valve. Take a flat head screwdriver and remove the sediment screen.

Clean the screen using soap and warm water mixture. If you find wear and tear in the valve, then please replace it.


It would be best if you took care while using the LG Icemaker. The door should be kept closed at all times, and it is better if you regularly remove excess ice from the icemaker from time to time.

You can also buy LG Refrigerator Ice Maker kits, which have all the things that you may need to keep your refrigerator working properly. However,
to avoid unnecessary expenses, you should maintain your refrigerator regularly so that it doesn’t suffer from unnecessary wear and tear.

You can also keep LG Refrigerator Ice Maker Maintenance guides that provide information on taking good care of your refrigerator to prolong its life. Keeping your refrigerator in good working condition is essential to prevent spoiling of the food inside it.

  1. Thanks for this. Our ice maker provided cubes, for awhile. Then it clogs up. We remove the unit, chop out the clog, and replace. Same cycle. Knowing this, which of the possible problems in this piece would be most likely ?

    1. Don, I have EXACTLY the same problem. Each week I have to open the ice maker and melt the ice with a hair dryer to get the holder out, then empty it and melt the ice build up in the area of the rotating blades and the ice build up in the “chute”. Replaced the compressor at year three. The interior design was not be anybody familiar with putting food in a refrigerator. When this LG goes, we’ll never see another one in our home.

  2. This is all well and good but I don’t expect to have to work on the ice maker in the one year old fridge freezer between “every” batch of ice! This has been going on for over a year now, I was advised to sell this fridge and buy a new brand and lose $1000 or $1500. The top freezer works fine but the reason we bought this freezer was for the bottom freezer! Bought 5-2020 one batch of ice and stopped, couldn’t get LG to send a repairman out until August 2020 ” that’s May to August” brand new fridge, finally the day before he was to come it made a batch of ” ICE ” so we were cancelled, it stopped a week later! LG finally found a local repair company to come out. It was a faulty water valve that looked like it was broken when they put it on. It worked for 3 or 4 months and went out again. Each time I have to call a repairman it costs me. The fridge is in a corner and the water was leaking out the back and we didn’t know until the carpet and wall board was damaged in the dining room, mold etc. LG talks a good talk but walks a bad walk, I’m venting but I want to warn others of this problem. Repair man comes again tomorrow. DeNene Jensen

  3. Fridge not making ice. Called customer service and had to tell the person who answered 5 times what my concern was. Then she told me to open and close the freezer door 3 times and that would solve the problem. Really? No! Still no ice. This is my first and more importantly my LAST appliance from LG. I would rather go to a store and purchase ice every day.

  4. Interesting suggestion: “If you confirm that the fill tube is frozen, you need to melt the excess ice by pouring hot water over the tube using a turkey blaster”. Shortly thereafter they warn of using a hair dryer to melt the ice because water may drip down onto wiring. Hmmmm.

  5. I seem to be getting an over spray of water. Freezing ice together and freezing the around the reservoir. What causes this in my LG french door refrigerator.

    1. It appears we have the same issue? Appears to much water into ice tray then overflows a bit causing ice to melt together and the reservoir to freeze so cfan not take out reservoir. Have you found a solution? I am believing it may be the water inlet value letting too much water in?

  6. I ‘ve had LG repairman thru warranty co Asurion who has never repaired problem with icemaker. Problem started when still under Asurion warranty but icemaker works for about 10 days and then when ice tray is full stops working and kicks out ice cubes in freezer. Each time arm that suppose to be on icemaker pops off. 1st time repairman left arm off. Next 3 times arm ended up twisted and dropped down into ice holder compartment. Made my 5th claim and was told I had to pay for repair because warranty

    Apparently 5 yr asurion warranty does not cover their repairs. So I get told by a rep that they will send out and cover at no cost and then I get an email that tells me I have to cover the cost of parts labor and svc fee.
    The Home Depot subcontract repairs out to A&E company based in AL.
    I think I want an old fashion icemaker i ndide where you flip up arm manually.

  7. Our ice maker is not even hooked up to the water line and we are getting major frost and ice on that side of the freezer. Brand new refridgerator this year. LG LFCS22520S . Anyone else having this issue?

  8. Have the same problem LG studio fridge 4 years old. Replaced compressor, still ice maker freezing ice in chute. Was told to replace whole door could be in door. At $1500 , even LG doesn’t know how to fix it let along a repair guy.

  9. Would a clogged waterline cause itvto pop out of the water inlet valve? This happens when I press the ice button. Or should I replace the water inlet valve?
