Start here
Most noise from a Dimchae refrigerator comes from how it is standing rather than from anything failing inside it, and a good half of the complaints turn out to be normal cooling sounds heard in a quiet room. The ranking below is ordered for this class of unit; only a knock at the compressor calls for a technician.
The symptoms, including the ones that mean something else
- One compartment behaves oddly while the others are fine — Each compartment here is controlled separately, which localises most faults.
- The noise stops the moment the freezer door opens — That points straight at a fan behind the freezer wall.
- NEAR MISS: the noise arrived with a cabinet that is no longer cold — Noise plus warmth is a cooling fault and the cooling page covers it.
What it usually turns out to be, ranked
- Normal cooling noises newly noticed — Ticking as the cabinet contracts, gurgling as refrigerant moves, a rush of air after a defrost and a fan stepping up in hot weather are all normal. Ranked first on a Dimchae refrigerator: brine, container choice and how full a compartment is packed all change the behaviour here, so usage comes first.
- The unit is not level, or it is touching a wall or a cabinet — A refrigerator transmits every vibration it makes into whatever it touches. Ranked second on a Dimchae refrigerator: nothing has failed here: the appliance is being asked to work in conditions it was never set up for.
- The ice-maker cycling — A unit with an ice-maker fills, freezes and then drops its ice with a solid thump on a schedule of its own. Ranked third on a Dimchae refrigerator: the mode selected changes the target completely on this design, so the setting is settled before any component is suspected.
- A unit working hard in a hot or enclosed spot — Fans speed up and the compressor runs far longer when the air around the unit is warm or cannot move. Ranked fourth on a Dimchae refrigerator: where the appliance stands changes what it is able to do, and that is cleared before anything inside it.
The order to work in, and the reason for it
- Note whether the noise follows the cooling cycle or runs constantly — A noise that comes and goes with the compressor is usually the compressor doing its job.
- Rock the unit corner to corner and check every foot is carrying weight — Anything that moves is a cause before anything inside the cabinet is.
- Switch the ice-maker off for a day and listen again — A noise that disappears with the maker off is settled without any tools.
Owner checks, in order
- Listen for a day and write down when the noise happens rather than what it sounds like — A pattern tied to the cycle tells you more than any single listen does.
About 15 min
- Level the unit front to back and side to side, then pull it clear of the cabinets — Leave the clearance the manufacturer asks for at the back and the sides.
Tools: spirit level, adjustable spannerAbout 20 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Safety first
Safety
Unplug the unit or switch off its breaker before removing any panel: a capacitor can hold a charge after the power is off. Refrigerant work is licensed work, so never cut, bend or solder the tubing, and never run the unit with the sealed system open. A loaded refrigerator is heavy and top-sided, so get help to move it rather than walking it on a corner.
Where an owner fix ends
Call when the unit is level, clear of the cabinets and still making a noise that rises with the compressor, because what is left is behind a panel. Call sooner if the noise is a metallic scrape or a knock at start-up, and call immediately if it comes with a burning smell.

The scope of this page
This page is written for the Dimchae refrigerator as a class, not for one family or model line. Shelf layouts, defrost-control types, fan placement and part numbers all change from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, it is the more specific answer and the one to read first.
