Direct answer
For the LG LF29S8330 refrigerator, freezer temperature, arm/bin state, water supply, filter and fill behavior should be proved first. First, confirm freezer temperature and that the ice maker is enabled.
What this covers
- LG LF29S8330 refrigerator (LF29S8330*)
- LG French-door refrigerator; InstaView, Craft Ice, ThinQ and linear/Smart Inverter compressor equipment varies.
- The specific fault this record addresses: ice maker is not making ice
What it does not cover
- ×The same symptom on a different LG product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The ice maker is switched off, or the arm is in the off position
What separates it No ice at all with everything else about the refrigerator working normally. The wire arm or the control switch is easily knocked into the off position when reaching into the freezer.
How to confirm Check the arm or the on/off control first. This costs seconds and is one of the most common causes.
- 2
The freezer is not cold enough to trigger a harvest
What separates it The mould contains water or partly formed ice that never releases, and the freezer temperature is above roughly 10°F.
How to confirm Ice makers use a temperature threshold to decide when the batch is frozen. A freezer running warm never reaches it, so the cycle never completes. Resolve the temperature first — see freezer-not-freezing.
- 3
The water supply line is closed, kinked or frozen
What separates it The mould stays completely dry. A saddle valve behind the refrigerator that was never fully opened, or a supply line pinched when the unit was pushed back, are the usual causes.
How to confirm A dry mould points at supply rather than freezing. A frozen fill tube is common where the freezer runs very cold and shows as ice blocking the tube itself.
- 4
The water filter is overdue or incorrectly installed
What separates it Ice production slowed before stopping, and the dispenser flow is also weak.
How to confirm A clogged filter restricts flow enough to stop ice production while still allowing a trickle at the dispenser. See filter-message.
- 5
The bin is being read as full
What separates it The bin is not actually full, but ice has fused into a solid mass or a piece is jammed against the sensor or arm.
How to confirm Empty the bin completely and break up any fused mass. Ice that partially melts and refreezes bridges into a block that reads as full.
- 6
The ice maker assembly has failed
What separates it Freezer temperature confirmed cold, water confirmed reaching the mould, arm on, bin clear, and still no harvest.
How to confirm This is the conclusion once every prerequisite is confirmed, and the assembly is usually replaced as a unit.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the mould is dry, holds water, or holds ice that never releases — each points at a different stage of the cycle.
- The actual freezer temperature, since a harvest will not trigger above roughly 10°F.
- Whether the arm or on/off control is in the on position.
- When the water filter was last replaced.
Confirm the ice maker is switched on and the arm is down
ReversibleThe arm is easily knocked up when reaching into the freezer, and this stops production entirely.
Check whether the mould is dry, holds water, or holds unreleased ice
ReversibleDry means a water-supply problem; water that never freezes out means a temperature problem.
Measure the freezer temperature and resolve it first if above roughly 10°F
ReversibleAn ice maker will not harvest until the freezer reaches its threshold, so temperature has to be fixed before anything else.
Confirm the supply valve is fully open and the line is not kinked or frozen
ReversibleCheck behind the unit, particularly if it was recently moved.
Empty the bin completely and break up any fused mass
ReversibleIce that melted and refroze bridges into a block the sensor reads as a full bin.
Allow a full 24 hours before judging whether production has resumed
ReversibleThe first batches after any correction are slow, and discarding them is normal.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- LF29S8330*. LG French-door refrigerator; InstaView, Craft Ice, ThinQ and linear/Smart Inverter compressor equipment varies.
- Type — 4-Door French door
- A 4-door French-door fridge (two fridge doors up top, two drawers below, often with a convertible middle drawer). Check a convertible drawer's mode if its temperature seems wrong.
- Ice — incl. Craft Ice
- Includes Craft Ice (slow round ice balls, a few a day by design) plus regular ice. Ice/water faults trace to the water line, filter and freezer temperature.
- Cooling — Linear Compressor
- Linear Compressor (10-year warranty), quiet variable-speed — a steady hum is normal. Dual evaporators separate the air paths.
- Symptom boundary
- This record covers LG LF29S8330 refrigerator when it ice maker is not making ice. A different symptom on the same hardware, or this symptom on a different LG product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Close the water supply for any leak at the fill valve or supply line.
- !Keep hands clear of the ejector mechanism, which can cycle without warning while the unit is powered.
Evidence ledger
Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. LG publishes this as "LG Refrigerator – Why is My Refrigerator Not Making Ice?". Ice maker producing nothing, with LG's water-supply, temperature and on/off checks. What that article does not carry is the model boundary — it is written for a product line, and LF29S8330* is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
The middle drawer on my LG LF29S8330 isn't the temperature I expect.+
Many 4-door LG fridges have a convertible middle drawer with its own temperature settings (from meat-chill to freezer), so check its selected mode in the panel — it may simply be set differently than you think. If a standard compartment is warm, look at blocked vents and door seals. The Linear Compressor's steady hum, meanwhile, is normal running, not a fault.
My ice maker just stopped for no reason.+
Check the arm or on/off control first — the wire arm is easy to knock into the off position when reaching into the freezer, and it stops production completely with no other symptom. After that, look at whether the mould is dry, which means water is not arriving, or holds water that never freezes out, which means the freezer is not cold enough to trigger a harvest.
The ice maker has water in it but never drops any ice.+
That points at freezer temperature rather than the ice maker. Harvest is triggered by a temperature threshold, usually around 10°F, and a freezer running warmer than that never reaches it — so the batch sits there indefinitely. Fix the freezer temperature first.
How long before I should expect ice after fixing something?+
Give it a full 24 hours. Ice makers produce in batches on a slow cycle, and the first batches after any repair or filter change should be discarded anyway.
Does this answer apply to every LG model?+
No. It is scoped to LF29S8330*. LG French-door refrigerator; InstaView, Craft Ice, ThinQ and linear/Smart Inverter compressor equipment varies.
What should I record before troubleshooting no ice or ice maker?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing no ice, ice maker. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Close water for leaks or overflow; keep hands away from moving ejector parts.
