LG refrigerator ice maker not filling with water

When your LG refrigerator ice maker is not filling with water, several problems could be happening behind the scenes. One of the first issues is a clogged water filter.

If you have a clogged water filter, you'd need to remove the filter and carefully clean it to get rid of any buildup blocking water from transferring from one spot to the next.

In addition, you may have a kinked water line. You’d need to inspect the water line and remove the damaged section before replacing it with a new fitting. You may also have a defective water inlet valve.

If the water inlet valve is the problem, you must replace it to get your refrigerator to produce ice again.

LG refrigerator ice maker freezing up

Have you noticed that your LG refrigerator ice maker is suddenly freezing up on you more often than not? If you have this problem, you may have the freezer temperature set too low.

Try to adjust the temperature and wait for a few hours to see if the adjustment makes a difference. If not, you’ll need to check your water line to see if there are any issues or blockages preventing water from flowing through and producing ice.

If so, you may need professional repairs for the water line to improve the situation and get ice coming out of your fridge again.

LG ice maker test button not working

If your test button is not working on the machine, there is a good chance that you have a broken machine. However, before you assume it’s broken and contact the manufacturer, you can try a few different things.

First, unplug the appliance, leave it unplugged for 30 seconds, and then plug it back in to see if the test button will turn on. It’s also possible that the control board to the appliance is malfunctioning.

If so, you may need to have the control board removed and replaced with an updated one that functions properly.

LG refrigerator ice maker not dumping ice

When the LG refrigerator ice maker isn’t dumping ice, it's usually because of the appliance's heating element. When the heating element begins to break, the chute becomes clogged, preventing the ice maker from dumping the ice that you want to have. [1]

Check the heating element and the chute to see if there is a problem. You may need to replace the heating element and then clean out the chute to ensure that it doesn’t get clogged again when dumping the ice out for you.

LG Ice Maker Not Turning On

If your ice maker isn’t turning on, you’ll need to try resetting it to see if that helps. In some cases, the ice maker needs a simple rest to begin working properly again.

When completing a reset, find the on/off switch, turn the appliance off, run an ice cycle, turn your appliance back on, and then give it up to eight hours to begin producing ice.

If this solution doesn’t work, you may have a faulty or broken device that needs replacing.

LG Freezer Temperature Issues

Many people experience temperature issues when they’re first dealing with an LG freezer. Be sure to check the thermostat attached to your freezer to see what you’ve set it to.

Make sure there is proper circulation in the freezer. If you have too many things inside the freezer, it can quickly lead to poor circulation. Try to adjust the way you’ve put items in your freezer to improve airflow and keep the temperature as cool as possible.
