The short answer
On a Twine refrigerator, most new refrigerator noises are mechanical and cheap — a fan touching ice, a loose panel, a cabinet that has gone off level. The sound tells you which. A small wine cabinet works against the room rather than against a load, so room temperature and door discipline decide almost everything below.
What you are actually seeing
- Bangs at intervals through the day — Ice release, or metal expanding and contracting through a defrost cycle.
- A gurgle or trickle a few minutes after the noise settles — Refrigerant settling and defrost water running to the tray. Both are normal.
- A rhythmic ticking or scraping that comes and goes — Usually a blade touching something once per revolution.
- NEAR MISS — a hiss with a smell — Stop, unplug the cabinet and call. Do not keep running it.
Causes, most likely first on this refrigerator
- Defrost, expansion and drain sounds that are not faults — Ranked first on Twine: a wine cabinet is quiet enough that its normal defrost trickle and expansion ticks are audible in a way they never are in a kitchen. On this one, remember that a small beverage cabinet works against the room, so the room is half the diagnosis.
- Condenser fan hitting debris or running on a worn bushing — Second: it keeps running with the doors open, which is the observation that separates it from the fan inside.
- Compressor vibration reaching the cabinet through a contact point — Third: it is common, it is free to fix, and it sounds far more serious than it is.
- Compressor or its mounts — Last, and that is the point of the order: a genuine compressor noise is a low grinding or a repeated start-and-stop, and it is far rarer than everything above it.
Check in this order, and why
- First — note whether the sound has a schedule rather than a constant presence — Sounds that appear a few times a day and last minutes are cycle sounds, not faults.
- Then — listen at the back or the grille with the doors open — A noise that continues with the doors open is on the condenser side, not the evaporator side.
- Third — with the compressor running, press gently on the panels and tubing at the back — If the noise changes or stops under a fingertip, you have found the contact point rather than a failing part.
- Only then — listen for a repeated start, buzz and stop rather than a steady hum — A compressor that tries and fails to start has a distinctive three-second rhythm, which is why it comes after everything above it.
What an owner can safely check
- Time the noise across a day before pulling anything apart — Note when it starts and how long it runs. A noise tied to the start and end of a cycle is almost always normal.
About 10 min
- Find the contact point and separate it — Unplug the cabinet, then look for tubing resting against the shell or a panel screw that has backed out. Separate the contact or re-seat the panel.
Tools: screwdriverAbout 20 min
- STOP before testing anything electrical with the power on — The checks above are all cold checks. Anything that needs power applied is where an owner check ends.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before any panel comes off, and give a capacitor time to discharge before you reach in. Never hold or tape a door switch closed to watch a fan run — the switch is what stops a blade turning while your hand is in there. A full-height cabinet is heavy and top-loaded; if you have to pull it out to reach the back, walk it, do not drag it, and have someone steady it. A full wine cabinet is heavy and its contents are not secured; unload it before you move it rather than after.
When it stops being an owner job
Call when the noise is a low grinding, when the compressor tries to start and stops repeatedly, or when the cabinet is getting warmer as well as louder. Call straight away for any hiss accompanied by a smell, or for any noise that appears together with a smell of burning. A noise on its own, with the cabinet still holding temperature, is rarely urgent — but a noise plus a temperature change is.

This page is written for the Twine refrigerator as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
