About this model

Model overview

Where the LB12S2000 fits

This number belongs to an 11.8 cu ft bottom-freezer, French-door LG refrigerator. It sits just below the LB12C2000 in capacity, and like that model it suits compact kitchens. No series name comes with this number, so what follows is about the layout rather than any trim level.

Frost is the headline problem

A drawer-style freezer under two doors relies on an automatic defrost cycle to keep the evaporator clear. When that cycle fails, frost thickens until it chokes the airflow, and the fresh-food side warms because the cold air no longer reaches it. The panel may show the defrost heating fault, a defrost sensor fault or a freezer fan fault. Each names a different link in the chain: heater, sensor, or fan. A coating of frost on the back wall is a clue for the technician; scraping it off is not a repair and the problem returns.

Gaskets and the drawer front

Frost that gathers near the drawer rim usually involves moist room air entering. The drawer gasket can stiffen, a basket can sit proud of its rails, or the drawer can sit slightly crooked on its slides. Read our write-up on frost around the freezer door to see how that differs from a defrost failure. How often the drawer is opened, and for how long, is worth mentioning to us.

Quick owner steps

  • Empty the drawer enough to see whether any item blocks the door from sealing.
  • Look at the gasket along its full length for folds or gaps.
  • Do not chip at ice with a tool; you may damage the lining.
  • Note when the warm shelf started and whether the drawer is still frozen.
  • Check the display for a code and write it down.

Booking

Provide the LB12S2000 label number, which is usually inside the fresh-food compartment or on a door frame, plus the symptom history. See LG refrigerator repair and the LG refrigerators overview. Diagnosis comes first, a written estimate follows, and nothing proceeds without your approval.

Preparing the freezer drawer for a visit

If the drawer can be emptied partly, we gain access to the back wall and the drawer rails. Please set frozen food in a cooler with ice rather than on the counter. A freezer that needs defrosting for the technician to test is a normal part of some visits, and the written estimate will say what the diagnosis found. If the drawer sticks on its slides, tell us before we begin so we can protect the rails.
