Quick answer
Confirm that the ice maker is on, the freezer is cold enough, and the refrigerator has had time to stabilize. LG points to water supply, a warm freezer, an off control, or recent installation as common causes. A model-specific test that will not cycle, or no ice after the documented waiting period, calls for service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Check the ice-maker power switch or the control-panel ice setting, then confirm the bin and ice-room door are seated as the model manual shows.
Expected result: The maker is off, the bin is misseated, or the ice-room door cannot close.
Next step: Correct the operating state and allow the production interval before judging the result.
Why this matters
Why: An off control or mispositioned bin can pause production without a failed motor.
-
Check 2
Measure or verify the freezer setting and ask whether the unit has been installed or powered for at least 24 hours.
Expected result: The freezer is warmer than the ice-making target or the unit is still within its initial stabilization period.
Next step: Restore the documented freezer setting and wait while keeping the freezer door closed.
Why this matters
Why: LG says insufficient freezing and recent installation can delay ice production.
-
Check 3
Check the home's refrigerator water valve and the accessible line or filter condition without disconnecting pressurized fittings.
Expected result: The supply is closed, the line is kinked, or water reaches the refrigerator normally.
Next step: Correct only an accessible valve or line issue, then allow a new harvest cycle.
Why this matters
Why: The ice maker cannot fill if water cannot reach its inlet; normal supply shifts attention to the maker's own cycle.
-
Check 4
With a towel below the ice maker, run only the model-specific test mode described by LG and observe whether the motor cycles and whether the tray receives water.
Expected result: The motor does not run, or it cycles without filling; alternatively it cycles and fills.
Next step: Record the exact result and request model-specific service for a failed or non-filling test; do not force the tray.
Why this matters
Why: A failed motor cycle suggests control, sensor, or motor diagnosis; a cycle without water keeps the supply/inlet path in question.

-
PATH 01Next step
What you see
The maker was off or the refrigerator has not reached the required cold temperature
Do this next
Turn it on or allow the documented period, then recheck production.
-
PATH 02Next step
What you see
The test motor runs but the tray does not receive water
Do this next
Check accessible supply conditions and arrange service if filling does not resume.
-
PATH 03Next step
What you see
The test motor will not cycle or ice still does not return after the waiting period
Do this next
Arrange service with the model number and the test result; do not bypass the mechanism.
Helpful context
Understand the symptom
Start with the symptom
No ice is not the same as ice that will not dispense. This page focuses on production: whether the maker is enabled, cold enough to harvest, and able to complete its own test cycle.
When checks do not resolve it
Need a professional?
Request service for a failed model-specific test, a persistent error, a leak, a repeatedly warm freezer, or no ice after the control, temperature, supply, and documented waiting checks.
Common questions
FAQ
How long can a new LG refrigerator take to make ice?
LG says a newly installed unit may need up to 24 hours for the ice maker to begin producing. Follow your model instructions and keep the freezer cold.
What does the LG ice-maker test tell me?
It helps show whether the motor cycles and whether water reaches the tray. Those two observations separate a mechanical/control concern from a supply or inlet concern.
