What is lg ice plus

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 water filter.

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 water filter and you noticed the ice maker started to leak, the problem can be with water pressure.

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 LG fridge there is a water hose connected to the inlet valve. If the water hose is kinked, it will restrict water flow to the inlet valve.

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 will fit with your model of the fridge !!!

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

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:

1. Remove Ice Bin from the compartment
2. Close the left door
3. Wait for 3 minutes
4. Freezer Door stays open
5. 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.
