Like other home appliances, your LG fridge ice maker can also experience issues every once in a while. The most common problems with these units are caused by temperature fluctuations on the ice maker compartment, a malfunctioned control board, faulty ice make fan in the freezer and a faulty water inlet valve among others reasons.

If you are having trouble with your unit, it is recommended you try troubleshooting the ice maker first before contacting LG support or repair services. Most issues can be resolved by troubleshooting the unit; which can save you money on expensive repairs and replacements. The following is a troubleshooting and how-to guide to help users resolve some common LG fridge ice maker problems. LG Refrigerator Ice Maker Freezing UpThe following reasons may cause a refrigerator ice maker to freeze up and not to dispense ice cubes: A faulty water inlet valveThe water valve lets water flow into the refrigerator. This water goes to the ice maker. If the water inlet valve is faulty, it can overfill the ice cube area and freeze up. This causes a frozen ice maker. Use a multimeter to check the water inlet valve on the back of the refrigerator. Check to see if the solenoid is working properly. If found to be faulty or leaking, remove and replace the valve. Frozen ice maker fill tubeThe ice fill tube is separate from the water lines but brings water to the ice maker. You may find the ice fill tube behind the ice maker. You can slide out the ice maker to access it. Check whether the tube is frozen or not. If frozen, you can thaw it in place with hot water using a baster or remove it from the ice maker and run it under hot water. Frozen water supply lineThe water line carrying water from the valve to the ice maker can become frozen. This can happen because the freezer temperature is too low or due to several other reasons. If you find your water lines frozen, try defrosting the complete refrigerator or you can try the hairdryer method to defrost the frozen water line. If the water lines continue to be frozen, turn the freezer temperature to a higher setting to try and keep the water lines from getting too cold. Freezer temperature is too coldIf the temperature in the freezer is too cold, the water can turn to ice too quickly. Simply turn the temperature in the freezer to the proper temperature settings. As per FDA recommendation, your freezer temperature should be 0oF (-18oC). Water filter needs replacingIf the refrigerator water filter is clogged, this can cause water pressure issues. Water pressure problems can cause the ice maker to freeze up. Replace the water filter. High or low water pressureCheck the water pressure going into the refrigerator. If the water pressure is too high or too low, the refrigerator ice maker may have issues with freezing. Water pressure above 120 PSI can cause the ice maker to freeze up. Water line positionIf the water line is pushed too far into the valve, this can cause a “splash back” effect which lets water into certain areas and freezes. The water line can be pushed further into the ice room and cause splash back from sliding the refrigerator back into position and against the wall. To fix this, check the water line for the proper positioning. LG French Door Fridge Ice Maker Not Dumping IceIf your refrigerator ice maker is not dispensing ice and there are no error codes on the display, try the following troubleshooting steps:
If the ice maker is not producing ice or the ice cubes are freezing too slowly, it is likely the door was left open. To troubleshoot and resolve this:
Where is the Reset Button in My LG Fridge Ice Maker?To reset the LG ice maker, locate the ice maker’s on/off switch on the left side of the unit. The refrigerator’s display will have an ice on/ice off icon. On the underside of the front of the tray there is a test/fill button. Press and hold that button until the ice maker starts to turn and run through a cycle. If the ice maker did not cycle, then you will need to remove the bin. LG recommends giving the ice maker a firm but gently shake a few times before replacing the bin and powering the unit off for 30 seconds. Turn the unit back on and let it sit for 6-8 hours before it starts to produce ice. LG Ice Maker Not Filling with WaterIf your LG refrigerator ice maker is not filling with water, check the following: Water filterWhen there is not filter or if the filter is not properly installed, water will not flow to the ice maker and water dispenser. To fix this, you only need to slide a filter into the housing, push and twist to lock it. If you recently replaced the water filter and you noticed the maker started leaking, the problem can be with water pressure. Water flows more freely when it is a new filter, and when it reached the ice maker it may create a splash. Some water will leak in the ice maker compartment to the bottom and on the floor. If you have a ball-type water tap behind the fridge, try reducing the incoming water pressure to the fridge to a desirable level. Inlet valveA faulty inlet valve can also be the reason your ice maker is not filling with water. To check the inlet valve you need a Multimeter. LG fridges have two inlet valves; the main valve on the back of the fridge and the secondary valve (for the ice maker) in the left door. You need to check both the valves. But, in many cases, the problem is with the secondary valve. Kinked water hoseThere is a water hose behind your LG fridge connected to the inlet valve. If the water hose is kinked, it will restrict water flow to the inlet valve. Failed motorIf the ice maker failed to perform diagnostic test and you are not able to run it, then most likely the ice maker motor failed. Faulty control boardIf the control board on your LG refrigerator is not sending power to the ice maker, or one of the relays on the control board has failed, then the ice maker will not run. If all the components mentioned above are ok and the ice maker works only when you press the RESET button, then there is a problem with the main control board or optical sensors on the ice maker. It is recommended that you replace the filter approximately every 6 months, when the water filter indicator reaches 0 months, or when the ice and water dispenser noticeably decreases out-put. To replace with a new cartridge, follow these steps:

LG Fridge Ice Maker Not Making Enough IceIf there is not enough ice or there is slow ice production in your LG fridge ice maker, consider the following troubleshooting instructions to resolve the problem:
LG Fridge Maker Not Turning ON At AllIf your LG French ice maker does not seem to work at all, check the following:
LG Fridge Ice Maker Ice Tray is Overfilling with WaterWater overfilling in the ice tray is usually caused by high water pressure in the home. However, depending on the type of ice maker that your fridge has, you can troubleshoot to correct the issue. If your CustomCube ice maker is overfilling with water, this is usually the result of the size selector being set too high. The size selector is to accommodate water pressure. Each size increment adds half a second to the amount of time the fill tube is open. If the water pressure is too high, it is necessary to choose a smaller size. Otherwise, the water will overfill the tray. If your Twist-N-Serve ice maker is overfilling with water, this is usually the result of the water pressure being too high. Close the water valve going into the refrigerator partially to reduce water pressure, or try purchasing a water pressure regulator to decrease the water pressure. This should address the issue by lowering the water pressure so that too much water doesn’t overfill the tray. Check this too: How to fix a mini fridge that won’t get cold If your 12 cube twist ice maker is overfilling with water, the flow sensor that determines the amount of water flowing to the ice maker may be malfunctioning. If so, the ice maker reverts to a timed fill. If the water pressure is high, the tray may also overfill. To check:
How to Turn Off an LG Fridge Ice MakerTo turn an LG refrigerator ice maker off, set the power switch to the off (O) position. If your unit has an on/off slide switch, you turn it off by sliding the switch, so the paddle is under the ice maker. For models without a switch; if there is no switch present, gently lift the metal feeler arm on the side of the ice maker to the up position to turn the unit off. To turn off an LG French door refrigerator ice maker (indoor ice maker operation), follow these steps:
How do you reset the ice maker on an LG French door refrigerator?To reset the ice maker, make sure that:
The water supply is turned ON, and no kinks should be in the lines. Press and hold the TEST/FILL button until the ice maker starts to turn/cycle.
Where is the ice maker reset button on LG?On the underside of the ice maker unit, you should be able to find a test/fill button. Once found, press and hold this button until the ice maker turns and starts a cycle. Once it runs through a cycle, it should start to fill up with water again and the ice production process will begin.
Why is my French door refrigerator not making ice?A clogged water filter, kinked water line hose, or defective water inlet valve can restrict the water flowing to an ice maker. When this happens, ice production will be limited or completely stop. Here's how to address water supply issues that can affect ice production: Change your refrigerator water filter.
Why won't my LG fridge dispense ice?Check the water inlet valve that fills the ice cube tray in case it may be leaking. Check the door gasket for any tears and rips. Make sure the gasket is properly connected to the liner. Another option is to lower the temperature of the freezer.
