Is your LG refrigerator dispensing water just fine, but the ice maker isn’t producing any ice? It’s a common issue, and in most cases, a simple DIY fix gets it working again without needing a technician. Here’s every likely cause, in the order worth checking, along with the fix for each.
Common Reasons an LG Refrigerator Isn’t Making Ice
Before working through the fixes, it helps to know what you’re likely dealing with:
- The ice maker is turned off by mistake
- Low water pressure is preventing proper ice formation
- A clogged water filter is restricting water flow
- The ice maker needs a reset to clear a minor error
- Frozen water lines are blocking ice production
- A defective component, like the ice maker motor or a sensor, has failed
Now let’s go through each one step by step.
1. Check If the Ice Maker Is Actually Turned On
Sometimes the fix really is this simple. Open the freezer and locate the ice maker switch — if it’s in the off position, switch it on and wait a few hours to see if ice production starts. Some LG models also have a Test button on the ice maker itself, which lets you check whether it cycles properly without waiting the full few hours.
2. Inspect the Water Supply and Water Pressure
Even if your fridge dispenses water normally, the pressure reaching the ice maker specifically might be too weak. To test it: disconnect the refrigerator’s water supply line, hold a cup under the dispenser, and press it. If the flow feels noticeably weak, low pressure is likely your issue.
Fix: Check for kinks in the water line first, since that’s the easiest thing to rule out. If the line is clear and pressure is still weak, the issue may be with your home’s water pressure more broadly.
3. Examine the Water Filter for Clogs
A clogged or aging water filter restricts flow enough to affect both ice production and water dispensing. Locate the filter, usually inside the fridge compartment, remove it, and check for visible blockage. If it’s older than six months, replace it with an LG-compatible filter — using a certified filter matters here, since off-brand filters don’t always seal or flow correctly.
After installing a new filter, run water through the dispenser for a few minutes first to clear any trapped air from the line.
4. Reset the LG Ice Maker
A reset clears minor glitches that can stop the ice maker from cycling properly. Locate the reset button on the ice maker itself, press and hold it for about 5 seconds until you hear a chime, then wait a full 24 hours to see whether ice production resumes.
5. Check for Frozen Water Lines
The line feeding water to the ice maker can freeze solid, cutting off supply entirely. Turn off the refrigerator, remove the ice bin, and locate the water line. Use a hairdryer on low heat to gently thaw any visible ice blockage, then restart the fridge and test the ice maker again.
If this keeps happening repeatedly, check whether your freezer temperature is set too low — the ideal range is 0°F to 5°F. A freezer running colder than needed makes the water line more prone to freezing solid.
6. Test the Ice Maker’s Components
If none of the above has worked, the ice maker itself may have a failed part:
- Ice maker assembly — if it doesn’t cycle at all, it may need replacing
- Water inlet valve — if faulty, water simply never reaches the ice maker
- Ice level sensor — a malfunctioning sensor can make the unit think the bin is already full when it’s actually empty
Replacing these components involves accessing internal wiring and water connections, so if you’re not confident working with either, this is a good point to call in a professional rather than risk further damage.
How Much Does It Cost to Fix an LG Ice Maker That Won’t Make Ice?
Cost depends entirely on which of these causes is behind it. Checking the switch, clearing a kink, or replacing a filter cost little to nothing. When a technician visit is needed, a fridge repair with Maydone starts with a flat diagnostic fee, applied toward the repair cost if you move forward. A water inlet valve replacement tends to be on the more affordable end, while a full ice maker assembly replacement costs more depending on the part and model. We confirm pricing before any work begins, and first-time customers get $30 off their repair.
When to Call a Professional Technician
If you’ve worked through every DIY step above and your LG ice maker is still not producing ice, it’s time to call in a professional. Signs it’s beyond a simple fix:
- The ice maker stopped working suddenly with no obvious cause
- Water pressure and the filter both check out fine, but there’s still no ice
- Your LG refrigerator’s display is showing an error code
- The ice maker is making unusual noises but not actually producing ice
Our technicians provide expert LG refrigerator repair across Vaughan, Mississauga, and the wider GTA, diagnosing and fixing ice maker issues quickly. Booking annual maintenance also helps catch a failing valve or sensor before it leaves you without ice entirely.

Frequently Asked Questions
Why does my LG refrigerator dispense water but not make ice?
This usually means the water supply itself is working, but something specific to the ice maker isn’t — a switch left off, a frozen line, a worn filter, or a failed internal component. Start with the switch and filter, since they’re the quickest to check.
How long should I wait after resetting the ice maker before assuming it didn’t work?
Give it a full 24 hours. Ice production can take that long to resume after a reset, even when the reset itself worked correctly.
How often should I replace my LG refrigerator’s water filter?
Every 6 months under normal use, or sooner if you notice reduced water flow or an odd taste. An overdue filter is one of the most common — and easiest to fix — causes of ice maker problems.
Can I use any water filter in my LG refrigerator?
Stick to an LG-certified filter rather than a generic off-brand one. Non-certified filters don’t always seal properly or maintain the flow rate the ice maker needs to cycle correctly.
Why does the water line to my ice maker keep freezing?
This often means your freezer is running colder than necessary. Check that it’s set within the 0°F to 5°F range — a freezer running noticeably colder than that increases the odds of the feed line freezing solid.
Is it worth replacing the ice maker assembly, or should I get a new fridge?
If the refrigerator is otherwise in good condition, replacing the ice maker assembly is almost always cheaper than replacing the whole unit. It’s worth getting an honest assessment from a technician if you’re unsure, especially on a fridge under 10 years old.
Checked the switch, the filter, and the water line — still no ice?
