Quick answer
A bad smell from LG ice is often held in old ice, the ice bin, the dispenser passage, or the water path rather than the sealed cooling system. Discard questionable ice, clean and dry removable parts as the manual directs, and replace the water filter only when the model calls for it. Do not use ice or water with a persistent chemical, sewage, or mold-like odor.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Compare the odor in a fresh glass of dispensed water, a new ice sample, and the empty ice bin after removing old ice; do not taste anything that smells unsafe.
Expected result: Odor is only in old ice/bin, or it is present in water and newly made ice.
Next step: Discard old ice and continue with cleaning; stop consuming water if the fresh sample remains abnormal.
Why this matters
Why: An old-ice/bin odor supports cleaning and replacement of stale ice; odor in fresh water and ice points toward the filter, supply, or dispenser path.
-
Check 2
Remove the ice bin if it releases normally, discard its contents, wash and dry it according to the manual, and wipe accessible dispenser surfaces with a clean cloth.
Expected result: The smell clears, or it returns after a clean dry bin is reinstalled.
Next step: Reinstall only when dry and request model-specific filter/service guidance if odor returns.
Why this matters
Why: A clear result supports stale ice or residue; recurrence suggests the water path, filter, or compartment needs diagnosis.
-
Check 3
Check the water filter status and installation against the exact LG model manual, replacing it only with a model-matched filter when due.
Expected result: The filter is overdue or incorrectly seated, or it is current while odor persists.
Next step: Flush/discard the initial water and ice as the manual directs; stop use and call service if the smell remains.
Why this matters
Why: A filter condition can affect water taste and odor; persistent odor with a current correctly installed filter needs further inspection.

-
PATH 01Next step
What you see
Only old stored ice smells and fresh water is normal
Do this next
Discard old ice, clean and dry the bin and passage, and make a fresh batch.
-
PATH 02Next step
What you see
Fresh water and newly made ice both smell abnormal
Do this next
Do not consume them. Check only the model-correct filter and supply basics, then request service or water-quality evaluation.
Helpful context
Understand the symptom
Separate stale ice from a water-source problem
Ice absorbs odors and can clump when unused. A smell in both dispensed water and new ice points more toward the supply or filter, while odor limited to stored ice points first toward the bin and passage.
Only after diagnosis
Potential parts
- water filter
Only consider this if the filter is due or the exact model manual links filter replacement to water taste or odor.
Confirm the exact refrigerator model and LG filter specification before ordering.
When checks do not resolve it
Need a professional?
Call when odor persists in fresh water or ice, water is discolored, a line leaks, or the filter and cleaning checks do not resolve it.
Common questions
FAQ
Should I keep using ice that smells strange?
No. Discard it and check the bin, passage, filter, and fresh water. Do not consume ice or water while a persistent abnormal odor remains.
Can I use a generic filter?
Do not assume compatibility. Use the exact model manual and manufacturer specification to identify the correct filter.
