LG refrigerators make great ice when everything's flowing, so when the icemaker stops it's usually because water, temperature, or the assembly itself has a problem. Here are the real causes in the order a tech checks them, plus the safe things to try yourself first.
A clogged LG filter chokes the water supply to the icemaker — the most common reason production slows or stops. LG recommends replacing it about every 6 months.
Check it: Replace the filter, dispense water several times to purge air, and allow 24 hours for a batch.
LG icemakers need the freezer around 0°F to harvest ice on schedule. A warm freezer — often from blocked vents or a weak seal — cuts production sharply.
Check it: Set the freezer to 0°F, keep food clear of the vents, and check the door seal.
The supply line behind the fridge can kink, work loose, or freeze, starving the icemaker. Low home water pressure can do it too.
Check it: Check that the line behind the fridge isn't pinched and the saddle/shutoff valve is fully open. A frozen line clears with a 24-hour power-off defrost.
LG icemakers have a Test/reset button; a stalled harvest cycle can sometimes be kicked back to life without any parts.
Check it: Press and hold the Test button on the icemaker until it chimes and cycles — keep hands clear as the tray rotates. If it won't complete a cycle, it needs a tech.
When water, temp, and resets are all good and there's still no ice, the icemaker assembly or the water inlet valve has failed and needs replacing.
Check it: This is the tech diagnosis and repair — we confirm the failed part and replace it.
Repair — LG icemaker assemblies and inlet valves are affordable and the fridge is worth keeping. Replacement only comes up on an old unit with a sealed-system failure on top of the ice issue.

Press and hold the Test/reset button on the icemaker until it chimes and starts a cycle (keep hands clear of the rotating tray). If it won't complete a cycle, check the filter and freezer temp, then call a tech.
Most often an overdue water filter, a freezer running too warm, or a kinked/frozen water line. Change the filter, confirm the freezer is at 0°F, and check the line behind the fridge before assuming the icemaker failed.
Often just a filter or a free reset; an assembly or inlet-valve replacement is an affordable part plus flat labor, and your $50 Quick Check credits toward it.
