Every heat wave, our phone fills with the same sentence: "The LG stopped making ice." Summer is exactly when ice makers work hardest and when their weak points surface — and LG's in-door design has a specific set of them. Here's the order we check things in, from free fixes to real parts.
1. The filter you forgot about
An LG ice maker doesn't need much water, but it needs it at pressure. A water filter past its six-month life chokes flow; the symptom is small, hollow, or crescent-shaped cubes before production stops entirely — and often a slow dispenser as a co-witness. If the filter is overdue, replace it first; it's the cheapest diagnosis in this article. One local wrinkle: homes with reverse-osmosis systems teed into the fridge line often run marginal pressure to begin with, and an aging filter tips them over the edge.
2. The frozen fill tube
The little tube that delivers water into the mold can freeze into an icicle plug — especially if the fill valve weeps slightly or freezer airflow hits it wrong. No water ever arrives; the ice maker cycles an empty mold. Thawing it gets you ice for a week; finding why it froze (weak valve, missing tube heater on models that have one, airflow) keeps the ice coming.
3. The in-door ice room icing itself shut
LG's signature move is the ice maker living inside the refrigerator door, in its own chilled compartment fed by a duct from the freezer. If the ice-room gasket wears or the duct seal leaks, humid kitchen air sneaks in and the whole compartment glaciates — frost on the mechanism, cubes welded together, an auger that groans. Clearing the ice is step one; restoring the seal is the actual repair, or you'll be chiseling again next month.
4. The fill valve and the icemaker unit itself
The dual water inlet valve at the back of the fridge opens on command from the board; a tired valve either trickles (thin ice, slow fill) or won't open at all. It tests conclusively with a meter. And sometimes the ice maker assembly is simply done — motor, thermostat or control gone — in which case LG's units are replaced as a module rather than rebuilt.
The five-minute owner check
Make sure the ice maker switch is ON (they get bumped), the bin is seated (a mis-seated bin parks everything), and the freezer is actually at 0°F — an ice maker in a 15°F freezer sulks and slows before anything is "broken." If those pass and you're still dry, it's diagnosis time.
Same-visit reality
Valves, filters and icemaker modules for common LG models ride in our van, so most no-ice calls around Lynnwood, Edmonds and Mountlake Terrace end with cubes dropping before we leave — fixed quote after the meter says which part earned the blame.
