No ice at all
The bin stays empty and you do not hear normal dump or fill sounds.
Start here: Check that ice making is turned on, then verify the freezer is cold enough before chasing parts.
Refrigerator ice maker troubleshooting
LG Refrigerator Not Making Ice
Direct answer: When an LG refrigerator is not making ice, the usual causes are the ice maker being turned off, the freezer running a little too warm, a restricted water supply, or an ice maker that is jammed or failing to cycle.
Most likely: Start with the easy stuff you can see: confirm ice making is turned on, make sure the freezer is actually cold enough, check for a kinked water line or overdue refrigerator water filter, and look for clumped ice blocking the mold or bin area.
Ice makers are picky. A refrigerator can keep food cold enough for daily use and still be just warm enough, starved enough for water, or jammed enough to stop making ice. Reality check: many 'bad ice maker' calls end up being a warm freezer or a simple water supply issue. Common wrong move: forcing the ice maker with a screwdriver or hair dryer and cracking the mold or trim.
Don’t start with: Do not start by ordering a refrigerator control board. On this complaint, settings, temperature, airflow, and water flow beat electronics most of the time.
If the freezer is above about 10°Ftreat this as a cooling problem first, because the ice maker usually will not cycle normally until the freezer is colder.
If the freezer is cold but there is no icefocus on water flow, ice blockage, and whether the refrigerator ice maker will harvest or fill.

What kind of ice-making failure do you have?
Small batch then nothing
It made some ice recently, then slowed down or stopped.
Start here: Look hard at freezer temperature, a restricted refrigerator water filter, or a partially blocked fill path.
Ice maker looks stuck or packed with ice
You see cubes fused together, frost around the mold, or the ejector area cannot move freely.
Start here: Clear the jam gently and look for signs of overfilling or a leaking refrigerator water inlet valve.
No water entering the ice maker
The mold stays dry and you never hear a brief fill after a harvest cycle.
Start here: Check the house water supply, refrigerator water line, and filter before suspecting the refrigerator ice maker assembly.
Most likely causes
1. Ice maker is off or paused
This is common after cleaning, power loss, bin removal, or someone bumping the control. The refrigerator cools normally, but no new ice starts.
Quick check: Confirm the ice maker is enabled and the shutoff arm or bin sensor area is not blocked by a bag, container, or frozen clump.
2. Freezer temperature is a little too warm
Ice makers need a properly cold freezer. A freezer that feels cold to your hand can still be too warm to cycle or fill reliably.
Quick check: Use a thermometer if you have one. If ice cream is soft, frost is building oddly, or the door has been left cracked, solve that first.
3. Water flow to the refrigerator is restricted
A kinked supply line, partly closed valve, or clogged refrigerator water filter can leave the ice maker dry or underfilled.
Quick check: Check whether the refrigerator water dispenser flow is weak, the supply line is pinched behind the unit, or the filter is overdue.
4. Refrigerator ice maker assembly or refrigerator water inlet valve is failing
If the freezer is cold, the controls are set correctly, and water supply is good, the ice maker may not harvest or the valve may not open cleanly for the fill.
Quick check: Listen for a harvest cycle and then a short fill call. A dry mold after a normal harvest points toward water supply or valve trouble; no harvest at all points more toward the ice maker.
Step-by-step fix
Step 1: Make sure the ice maker is actually allowed to run
A disabled ice maker or blocked shutoff area is the fastest, safest fix and it gets missed all the time.
- Open the freezer and confirm the ice maker is switched on or enabled at the control panel.
- Make sure the ice bin is seated correctly and not pushing against the ice maker shutoff arm or sensor area.
- Remove any bagged food, loose cubes, or frost clumps that could make the ice maker think the bin is full.
- If the refrigerator was recently installed or moved, give it time if it has only been running a short while.
Next move: If ice production starts again within the next day, the problem was a setting, bin position, or simple blockage. Move on to freezer temperature. An ice maker that is on but still idle usually needs colder conditions or better water flow.
What to conclude: You ruled out the easiest false alarm before getting into water or component checks.
Stop if:
- The ice maker housing is cracked or loose.
- You find melted and refrozen ice around wiring or trim.
- The freezer door will not close or seal properly.
Step 2: Check whether the freezer is cold enough for ice production
A slightly warm freezer is one of the most common reasons a refrigerator stops making ice even though the rest of the unit seems mostly fine.
- Check the freezer setting and make sure it was not turned warmer by mistake.
- Look for obvious airflow problems: packed food against vents, heavy frost on the back panel, or a door left ajar.
- Feel the food condition. Soft ice cream or slushy frozen items usually means the freezer is too warm for normal ice making.
- If you have a refrigerator thermometer, place it in the freezer and verify the temperature after it stabilizes.
Next move: If lowering the temperature and restoring airflow brings ice back, the ice maker was waiting on proper freezer conditions. If the freezer is cold enough and steady, go to the water supply checks.
What to conclude: This separates an ice maker problem from a broader refrigerator cooling problem.
Step 3: Check water supply to the refrigerator before blaming the ice maker
No water in means no ice. A restricted line or filter is more common than a failed internal part.
- Pull the refrigerator out carefully and inspect the refrigerator water supply line for kinks or crushing.
- Make sure the house shutoff valve feeding the refrigerator is fully open.
- If your refrigerator has a water dispenser, test the flow. Weak dispenser flow often points to a supply or filter restriction.
- If the refrigerator water filter is overdue or dispenser flow has dropped off, replace the refrigerator water filter and purge air from the line as directed for your unit.
- Look for ice buildup at the fill area that could block incoming water.
Next move: If dispenser flow improves and the ice maker starts filling again, the restriction was in the supply path, often the filter or line. If water supply is strong and the freezer is cold, the problem is more likely inside the refrigerator at the ice maker or inlet valve.
Step 4: Clear a jammed mold or frozen fill area and watch for the next cycle
Ice clumps, a frozen fill path, or a stalled ejector can stop production even when temperature and water supply are otherwise close to normal.
- Remove the ice bin and dump out fused or oversized clumps.
- Inspect the ice maker mold and ejector area for cubes stuck halfway out or frost locking the mechanism.
- If you see light frost or loose ice blocking movement, clear it gently by hand and wipe the area dry.
- Check the fill area for a small ice plug. Repeated ice plugs often point to a seeping refrigerator water inlet valve or temperature issue.
- After clearing the obstruction, reinstall the bin correctly and monitor for a normal harvest and refill.
Next move: If the ice maker resumes a normal dump-and-fill pattern, the immediate problem was a jam or frozen blockage. If it stays dry or never harvests again, the likely failure is the refrigerator ice maker assembly or the refrigerator water inlet valve.
Step 5: Replace the part that matches what you just proved
By this point you should know whether the refrigerator is failing to harvest ice, failing to fill with water, or failing to stay cold enough for ice production.
- Replace the refrigerator water filter if flow was weak and the old filter was overdue.
- Replace the refrigerator ice maker assembly if the freezer is cold, the controls are correct, the bin area is clear, and the unit will not harvest normally.
- Replace the refrigerator water inlet valve if the ice maker calls for water but does not fill, or if the fill area keeps icing up from a valve that seeps.
- If the freezer is not holding proper temperature or you have heavy frost on the back wall, stop chasing the ice maker and address the refrigerator cooling problem first.
A good result: A correct repair should restore normal ice production after the freezer returns to temperature and the ice maker completes its next cycles.
If not: If a cold freezer with good water supply still will not make ice after the matching repair, the diagnosis has moved beyond simple DIY and needs model-specific electrical testing.
What to conclude: You are no longer guessing. You are matching the repair to the failure pattern you observed.

FAQ
Why did my LG refrigerator stop making ice all of a sudden?
Most sudden no-ice complaints come from the ice maker being switched off, the freezer warming up slightly, a blocked fill area, or reduced water flow through the refrigerator filter or supply line. Start there before assuming a major part failed.
Can a refrigerator make no ice even if it still seems cold?
Yes. The freezer can feel cold enough for food but still be too warm for reliable ice production. That is why checking actual freezer temperature matters.
How do I know if the problem is the refrigerator water filter?
Weak water dispenser flow, smaller cubes, slow production, or no fill at the ice maker all point toward a restricted filter or supply path. If the filter is overdue, that is a strong first correction.
What if the ice maker tray keeps freezing up?
A frozen fill area or repeated ice plug often means water is seeping past the refrigerator water inlet valve or the freezer has had a temperature or door-seal problem. Clearing the ice once is fine, but repeat freeze-ups usually mean the root cause is still there.
Should I replace the refrigerator control board if the ice maker is not working?
Not first. On this symptom, controls are not the usual winner. Prove settings, freezer temperature, airflow, water supply, and the ice maker or inlet valve before considering an electronic control issue.
