LG LF29S8330 refrigerator makes buzzing, clicking, rattling or knocking noises

LG LF29S8330 refrigerator makes buzzing, clicking, rattling or knocking noises: many water, fan, compressor and expansion sounds are normal; location, duration and temperature effect identify abnormal noise. Scoped to LF29S8330*.

An LG LF29S8330 that makes a noise is a four-door French-door refrigerator with a Linear Compressor and Craft Ice, and the first step is to know which noises belong. This model has a quiet, variable-speed compressor under a 10-year warranty, dual evaporators and a convertible middle drawer. A steady low hum is normal, as are a faint gurgle of refrigerant, clicks as the defrost heater cycles and the thump of ice dropping into the bin.

The checks in more detail

The Craft Ice maker also makes sounds as it forms and releases its slow, round ice balls, a few a day by design. A louder or unusual noise has its causes. A rattle or a buzz often comes from the refrigerator touching the wall or the cabinet, from a drip pan or a panel that has shaken loose, or from a loose item on top. Move the unit slightly away from the wall and make sure it is level, with the front feet adjusted so that the doors close by themselves.

A fan noise, a whirring or a chirp comes from the evaporator fan in the freezer or the condenser fan at the back; frost or a bit of ice on the fan blade causes a scrape, which a defrost can cure. A squeal or a loud hum from the compressor area is not normal and, with the model's linear compressor, deserves a call to LG. Check the simple things.

Clean the condenser area behind or below the refrigerator, since dust makes the fan work harder and noisier. Listen with the doors closed and then open, and notice whether the noise stops with the door open or the ice maker off, which points at the ice maker or the fan. The convertible middle drawer has its own air path, so a fan noise near it may be that. Note when the noise happens and quote LF29S8330S and the serial number if you contact LG.
