The short answer
Most new refrigerator noises are the cabinet telling you about its installation rather than about a failing part. On an imported mass-market cabinet the ranking below follows how the cabinet is built and where it usually sits, and the top two causes cost nothing to rule out.
What you observe
- A buzz or rattle that changes when you touch the cabinet — A contact or a resonance rather than a component.
- A whirring or chirping from the freezer section — Something turning behind the rear panel, usually the evaporator fan.
- NEAR MISS: gurgling and ticking after the cabinet cycles off — That is refrigerant settling and metal contracting.
Causes, most likely first on this cabinet
- Something touching the cabinet or sitting on it — A drip tray, a wall, a cabinet side, a bottle on top or a coiled water line all turn a normal vibration into a noise. Ranked first on Daewoo Electronics: these cabinets are built to a price on a deliberately plain platform, so the simple mechanical causes really are the common ones and the exotic ones really are rare, and the electronics-plate control generation adds a layer that the mechanical platform underneath does not.
- The condenser fan at the back or underneath — Debris in the blade, or a bearing at the end of its life, both produce a rattle that tracks the compressor running. Ranked second: it sits here because it mimics the cause above it closely enough that checking in the wrong order wastes a visit.
- The evaporator fan behind the freezer panel — A worn bearing chirps or squeals, and a blade brushing frost clatters. Ranked third: it is placed here because it is the first cause that needs more than a look.
- The compressor or its mounts — Rubber mounts harden with age and let the compressor case drum against the frame. Ranked last: it is last because it is genuinely uncommon on this platform, and because it is the one cause an owner cannot confirm or fix without licensed tools.
Check in this order, and why
- Pull the cabinet clear of the wall and run it — If the sound goes, you have found it.
- Listen at the back grille while the cabinet is running — A sound that starts and stops exactly with the compressor is on the condenser side.
- Open the freezer and hold the door switch in — The sound rising as the fan spins up puts it here rather than anywhere outside the box.
What an owner can safely check
- Pull the cabinet out, clear the top and re-seat the drip tray — Leave the specified clearance at the back and check that no water line or cord is pressed against the cabinet skin.
About 10 min
- Unplug the cabinet and clear the condenser fan area of debris — Take the rear access panel or the toe grille off with the power off, and clear whatever has been drawn into the fan.
Tools: screwdriver, vacuumAbout 25 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.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before taking off any panel or reaching behind the rear grille, and keep it off while your hands are inside: a capacitor can hold a charge after the power is off, and a condenser fan can start without warning. Do not hold a freezer door switch in with tape and then leave the cabinet unattended. If you move the cabinet to reach the back, walk it rather than dragging it, and keep the water line slack so it is not pulled out of its fitting.
When to call a technician
Call when the noise comes with a loss of cooling, when it comes from behind a panel you would need to remove, or when it is a hard metallic knock rather than a rattle or a hum. A noise on its own, with the cabinet still holding temperature, is rarely urgent.

What this page does not cover
This page covers the Daewoo Electronics refrigerator as a class, not one model or production run. Any family- or model-specific page for your unit takes precedence over it. Not here: part numbers for fan motors and mounts, and the disassembly sequence for your specific cabinet, both of which vary by model line.
