Quick answer
Confirm the ice maker is on, the freezer is cold enough, water is available, and the unit has had time to stabilize. If a model-specific test fails or ice does not return after the reset and waiting period, arrange service instead of forcing the mechanism.
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 control, bin position, and ice-room door using the model manual for the layout.
Expected result: The ice maker is off, paused, the bin is misseated, or the door cannot close.
Next step: Correct the position or switch the control on, then allow stabilization.
Stop if: Continue to temperature and water checks.
Why this matters
Why: An operating-state or cold-air issue can stop production.
-
Check 2
Check the freezer temperature and whether the refrigerator has operated at least 24 hours after installation or a long interruption.
Expected result: The freezer is warm or the unit has not stabilized.
Next step: Restore normal cooling and wait the documented period.
Stop if: Continue to the model-specific test.
Why this matters
Why: Insufficient freezing or startup delay can prevent ice without a failed ice maker.
-
Check 3
With a towel below the unit, run the model-specific test button or test mode exactly as shown by LG.
Expected result: The motor fails to cycle, or it cycles but no water enters.
Next step: Record the result and arrange service; do not force the tray or probe wiring.
Stop if: If it cycles and fills, allow the production interval and monitor the bin.
Why this matters
Why: A failed cycle suggests motor/control diagnosis; a cycle without water points toward supply, filter, inlet, or valve conditions.

PATH 01Next step
What you see
The ice maker is off or the refrigerator has not stabilized
Do this next
Turn it on or wait for the stated stabilization period.
-
PATH 02Next step
What you see
The test motor does not run
Do this next
Arrange model-specific service without forcing the mechanism.

PATH 03Next step
What you see
The test cycles but does not fill
Do this next
Check only accessible supply/filter conditions and arrange service if flow does not return.
Helpful context
Understand the symptom
Follow the symptom
No ice can result from a recent installation, an off control, inadequate freezing, a water-flow problem, or a failed motor or sensor. Whether the test motor runs and whether water reaches the tray changes the next step.
When checks do not resolve it
Need a professional?
Use LG model-specific service for motor, sensor, valve, or control faults.
Common questions
FAQ
How long should I wait after turning on an LG ice maker?
Use the model instructions; LG notes a newly installed unit may need at least 24 hours before production begins.
What if the ice-maker test does not run?
Record the result and arrange service. Do not force the tray or bypass sensors.
