LG LK12S6000 refrigerator repair

A compact top-freezer

LK12S6000 is listed as a top-freezer refrigerator at 11.7 cu ft, with no series name. A freezer compartment above and a fresh-food section below is the oldest and simplest layout, and it is common in rentals and small kitchens.

Water on the floor

The most frequent complaint on a top-freezer is a puddle inside or under the unit. During defrost, melt water runs down a trough to a drain and then to a pan beneath the cabinet. When that drain freezes or clogs with debris, the water spills into the bottom of the fresh-food compartment instead. Defrost heater trouble can cause the freeze-up, which the panel may report as the defrost heating fault. A technician clears the drain and then finds out why it froze.

Warm below, cold above

When the freezer holds and the lower compartment warms, the usual cause is limited airflow between the two. Ice on the evaporator or a stalled fan stops cold air from being sent down. Our article on a refrigerator that is warm while the freezer is fine describes the order of checks. The refrigerator fan code helps if the display is active.

Rental kitchens and floors

Many San Francisco tenants share a kitchen with an older floor that tilts slightly. A top-freezer leaning forward lets the doors close, but one leaning back leaves them ajar. Level it by turning the front feet before suspecting the door seal. If the unit was moved recently, check that the cord and any supply line were not stretched.

What owners can do

• Look for ice on the back wall of the freezer and leave it, as scraping is risky.
• Move food away from the rear vents.
• Wipe the door gasket.
• Notice whether the water appears only after a few hours of running.

Booking

Photograph the LK12S6000 label, usually inside the fresh-food side wall. Our LG refrigerator repair page describes the visit and LG refrigerators lists the lineup. We diagnose, write up an estimate and wait for your approval.

Before moving it for cleaning

Many renters pull the refrigerator forward to clean behind it and then find a problem. Turn off the water supply if the unit has one, slide it out slowly on a flat path and avoid tipping it. Check the cord for crushing, and push it back only far enough to leave an air gap behind. If a leak showed up after the move, tell us what you did.
