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 — French door: A French-door fridge with a bottom freezer. A mainstream LG layout.
Ice & dispenser: Automatic ice maker; dispenser on dispenser builds. Ice/water faults trace to the water line, filter and freezer temperature.
Cooling — Linear Compressor: Linear Compressor (10-year warranty), quiet variable-speed — a steady hum is normal. Keep interior vents clear for even cooling.

Exact questions

Questions that only have an answer for the LG LF21G6200 counter-depth 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.

My LG LF21G6200 is building up frost inside.+

A little frost near the vents is normal, but heavy frost usually means warm, humid air is getting in — check the door seals for gaps or food holding a door ajar, and do not leave doors open long. Frost specifically on the back wall of the fridge can be a defrost-system issue (heater/sensor), which needs service. Make sure the drawers and vents are not blocking airflow, which causes uneven cold spots and frost.
