Which units this covers, and how to tell yours is one of them
Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.
- Model numbers and patterns
- LTCS20020*
- What that covers
- LG LTCS20020 top-freezer refrigerator. LG's own specification for this model states no ice and water dispenser: ice is a manual tray or the optional LK65C ice-maker kit, so dispenser, plumbed ice and water-filter symptoms do not apply to it as sold.
- Not applicable to this hardware
- This LG LTCS20020 top-freezer refrigerator does not have the hardware for: ice maker is not making ice; makes small, hollow or misshapen ice; water dispenser is slow or not working; water-filter light will not reset or filter message remains. Those symptoms have no page here for this model rather than a page that guesses.
Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Type — TOP-FREEZER (no dispenser, no factory ice maker)
- An entry TOP-FREEZER refrigerator that ships with NO through-door water/ice dispenser AND NO factory ice maker (verified). So dispenser and ice-maker symptoms do not apply to this model — you use ice trays and fill water manually. This simplicity is also why top-freezers are the most reliable layout.
- Optional ice-maker kit
- Some LTCS models can accept an add-on ice-maker kit, but as shipped there is none — if yours has no ice maker installed, 'ice maker not working' means there is no ice maker to work, not a fault.
- Cooling
- A single cooling system, freezer on top. If the fridge is warm but the freezer cold, the vent passing cold air down to the fridge is likely blocked by packed food or iced from a defrost issue — clear it and avoid overpacking the top shelf.

Exact questions
Questions that only have an answer for the LG LTCS20020 top-freezer refrigerator
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
Why doesn't my LG LTCS20020 make ice or dispense water?+
Because it does not have those features — the LTCS20020 is an entry top-freezer that ships with no through-door dispenser and no factory ice maker, so you make ice in trays and fill water by hand. It is not broken; the functions were never installed. Some versions can take an optional add-on ice-maker kit, but out of the box there is nothing to troubleshoot for ice or dispensing.
