Having an ice maker in your LG refrigerator provides the convenience of instant ice whenever you need it. However, when that ice maker stops working properly, it can be a real headache. As an LG refrigerator owner myself, I’ve been there! When my ice maker suddenly stopped producing ice, I was frustrated. But with a little troubleshooting and diagnosis, I was able to get my ice maker working again.
In this article, we’ll walk through the common problems that can cause an LG ice maker to stop working, along with steps you can take to troubleshoot and fix the issue yourself. With the right information and a few tools, you can often repair your LG ice maker without the hassle and expense of calling a repair technician.
Why Is My LG Ice Maker Not Working?
There are a number of reasons why your LG refrigerator’s ice maker may not be producing ice:
- The ice maker is turned off – Check the control panel on the door of your refrigerator to ensure the ice maker is turned on. There may be a button or switch to activate the ice maker.
- Ice maker arm is stuck – The arm that senses when the ice bin is full can sometimes get stuck. Make sure it moves up and down freely.
- Water supply issue – If the ice maker isn’t getting water, it can’t make ice. Ensure the water supply valve is open and check for kinks or clogs in the supply line.
- Freezer temperature too warm – The freezer needs to be around 0°F for the ice maker to properly operate. Check the temperature setting.
- Ice maker mold, sensor or heating element failure – Like any appliance, the various internal components of the ice maker can fail over time. We’ll go into more detail on these issues below.
- Mineral buildup or ice blockage – Ice makers can build up mineral deposits over time or even freeze up. Carefully inspect and clean the ice maker assembly.
By going through some systematic troubleshooting steps, you should be able to diagnose the specific problem with your LG ice maker.
Step-by-Step LG Ice Maker Troubleshooting
Here are the key things to check when your LG refrigerator is not making ice:
1. Verify the Ice Maker is Turned On
This may sound obvious, but first double check that the ice maker is actually turned on. Many LG refrigerators have an enable/disable button or switch for the ice maker on the control panel. Make sure this is set to the “On” or “Enabled” position.
If you don’t see an obvious button, consult your owner’s manual to determine how to activate the ice maker. On some models, you may need to hold down an icon or button for 3 seconds to toggle the ice maker on or off.
2. Check if the Ice Maker Arm is Stuck
The ice maker arm acts as a sensor to determine when the ice bin is full. When the bin fills up with ice, the arm is designed to automatically lift up to the “off” position, stopping ice production.
Over time, residue from water and ice can cause the arm to stick in the up or down position. Visually inspect the arm inside the ice bin to make sure it can move up and down freely.
If it is stuck, gently clean the hinges and shaft with warm water and baking soda. That should free up the arm so it can properly sense when more ice needs to be made.
3. Verify Water is Getting to the Ice Maker
No water, no ice. If water can’t get to the ice mold, the freezing process can’t begin. There are a few things that could interrupt the water supply:
- Water supply valve – Behind your refrigerator is a water valve that feeds water into the ice maker. Make sure this valve is fully open.
- Kinked supply line – Check for kinks or tight bends in the 1/4″ plastic water supply line. Straighten or repair any issues in the line.
- Clogged tubing – Sediment buildup or impurities in the water can clog the small supply tubes leading into the ice mold. Disconnect and inspect the tubing for blockages.
- Water filter issue – If your refrigerator has a water filter, a saturated or clogged filter cartridge could restrict water flow. Try replacing the filter and monitoring if that improves ice production.
Once you’ve verified the water supply components are in good shape, test by pouring some water directly into the ice mold. If it drains through properly, you know water is able to get where it needs to go.
4. Check the Freezer Temperature
In order for the ice maker to reliably produce ice, the freezer needs to maintain a temperature of around 0°F or slightly below. If the freezer is not getting cold enough, ice production will slow or stop completely.
Access the temperature settings through the control panel on your LG fridge. For proper ice production, set the freezer to 0°F or -3°F, depending on your model.
Let the freezer run for at least 24 hours at the colder setting to allow temperatures to stabilize. Check if ice begins forming once your freezer cools down again. Call for service if temperatures do not get cold enough after adjustment.
5. Inspect the Ice Mold, Ejector and Heating Elements
The core ice-making components include the mold, ejector and heating mechanisms. Issues with any of these systems can halt ice production:
- Ice mold – Cracks, warping or dirt buildup on the ice mold can prevent water from properly freezing. Clean the mold with mild soap and water or replace it if damaged.
- Ejector – This mechanism pushes the ice out of the mold once frozen. Fix any stuck mechanisms and ensure it can move smoothly.
- Heating elements – Heaters under the mold regulate the ice making process. If not working, new heating elements may be required.
Carefully inspect each component and test its operation. Make repairs, replace parts or clean as needed.
6. Check for Mineral Buildup and Ice Blockages
Just like any appliance, ice makers accumulate mineral deposits and sediment over years of use. This can interfere with water flow, ice ejection and overall functionality.
Unplug the fridge to safely access the ice maker assembly. Check for any blockages or buildup:
- Remove all ice from the mold, ejector and shafts. Defrost completely if needed.
- Clean the ice mold and interior surfaces with a mix of vinegar and warm water.
- Use a nylon brush to scrub out sediment clogging any water tubes or channels.
- Inspect the water fill tube for any blockages preventing water from entering the ice mold.
Taking the time to descale and clean the ice maker can get it working again in many cases. Be sure to reattach all mechanisms tightly once finished.
When to Call for Professional LG Ice Maker Repair
If you’ve worked through all the troubleshooting steps and your LG ice maker still isn’t operating correctly, it may be time to call in a professional. A trained appliance repair technician can fully diagnose the issue and make any necessary repairs.
Here are some signs it’s time to contact LG customer support or look for professional assistance:
- You’ve verified freezer temps are correct, but ice production is still stalled. This points to an internal mechanical or electrical issue needing repair.
- There are obvious cracks, damage or wear to the ice mold, ejector arms or other components. Damaged parts will need to be replaced.
