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.
