What is true of this model and changes how you fix it
- 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 kitSome 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.
- CoolingA 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.
- A simple layoutA single cooling system and few electronics make the top-freezer the most reliable layout. You make ice in trays and fill water by hand.
- An optional ice-maker kitSome LTCS models can accept an add-on ice-maker kit, but as shipped there is none. If yours has no ice maker, a complaint of ice not working means there is nothing to work, not a fault.
- CoolingIf the fridge is warm but the freezer is cold, the vent that carries cold air down to the fridge may be blocked by packed food or iced from a defrost issue. Clear the vent and avoid overpacking the top shelf.
- NoiseA top-freezer hums and clicks like any refrigerator, and its simplicity makes the sounds easy to learn: a hum from the compressor, a fan whoosh and the click of the defrost cycle.
- Finding the model numberThe label is on the inside wall of the fresh-food compartment; LG lists the full model as LTCS20020S.
- Defrosting a top-freezerA manual or auto-defrost top-freezer can build frost on the freezer's back wall if the door is left open or the seal leaks. A thick frost blocks the vent that carries cold air down to the fresh-food side.
- Using trays for iceWithout an ice maker, fill trays with tap water, freeze and store the cubes in a covered container. Ice stored for weeks absorbs odors, so use it within a few weeks and wash the container.
