Covered records
LG Refrigerator dH: LG documents dH as a defrosting failure; F dH, r dH and Er dH displays and recovery procedures depend on the exact model.LG Refrigerator dS: LG documents dS as a defrosting-sensor error that requires service; the prefix identifies the evaporator configuration or compartment.LG Refrigerator FF: LG documents FF as an abnormality with the freezer compartment fan motor.LG Refrigerator gF: LG’s US code list documents gF as a flow-sensor or low-water-pressure warning; the ice-maker type and full display determine the applicable guidance.LG Refrigerator rF: Most LG sources describe rF as an abnormality with the refrigerator compartment fan motor.

Coverage gaps
- 40E is referenced for context but does not yet have a dedicated reviewed record in this brand/appliance cluster.
- 5E is referenced for context but does not yet have a dedicated reviewed record in this brand/appliance cluster.
- Exact model-family pages remain gated until an official or manual-backed source supports the model-specific wording.
- Parts and service handoffs are not shown as recommendations until the source context is strong enough.
How this guide should be used
- Use the source links to verify the original manufacturer context.
- Check model notes before treating a display code as universal.
- Prefer safe first checks before any disassembly or parts decision.
Current limitations
- Manufacturer guidance can differ by model family and region.
- Alias/display variants are only added when the source supports them.
- Manual-backed model detail is planned but not bulk-generated.
