LG Ice Maker Not Working
An ice maker that stops producing is usually a water-supply problem — a closed shutoff, a frozen fill tube, or an overdue filter — rather than a failed ice maker module.
What's specific to LG
LG ice makers are commonly starved by an overdue water filter or a frozen fill tube. LG filters are rated around six months and are a frequent cause of gradually declining ice production.
Causes, in order of likelihood
| Cause | How often | Typical cost |
|---|---|---|
| Overdue water filter | Most common | DIY |
| Frozen fill tube | Most common | DIY to thaw |
| Ice maker arm or switch left off | Common | DIY |
| Freezer running too warm | Common | Varies |
| Failed water inlet valve | Less common | $180–$380 |
| Failed ice maker module | Less common | $250–$550 |
1. Overdue water filterYou can check this
How to check: Filters are typically rated for six months. A clogged filter starves the ice maker before it noticeably affects the dispenser.
The fix: Fit a new filter and discard the first few batches.
2. Frozen fill tubeYou can check this
How to check: A plug of ice in the small tube that feeds the mould. Often accompanies hollow or undersized cubes.
The fix: Thaw the tube gently with warm air. If it refreezes, the inlet valve is likely leaking through.
3. Ice maker arm or switch left offYou can check this
How to check: A wire bail arm in the raised position, or an off setting in the control panel, halts production entirely.
The fix: Lower the arm or switch production back on.
4. Freezer running too warmTechnician job
How to check: Ice makers need roughly 0–10°F to cycle. Above that the harvest cycle stalls.
The fix: Fix the underlying cooling fault first — the ice maker is a symptom, not the cause.
5. Failed water inlet valveTechnician job
How to check: No water reaches the mould even with the filter changed and the tube clear.
The fix: Replace the inlet valve.
6. Failed ice maker moduleTechnician job
How to check: Water fills the mould but the harvest arm never ejects the cubes.
The fix: Replace the ice maker assembly.
When to call a technician
If water reaches the mould and the freezer is cold enough but no ice ejects, the module or the control has failed.
