The short answer
A noisy design-led compact refrigerator is usually telling you one thing: a rear panel, drip tray or pipe is buzzing against the shell. Next on the list: the cabinet is rocking on an uneven floor. Almost everything here is housekeeping rather than a failing compressor; the one service job sits at the bottom and sounds quite different.
What you observe
- A new sound the cabinet did not make when it was installed — What matters is whether it tracks the compressor, a fan, or your hand.
- A buzz that stops when you lean on the cabinet — Only contact noise responds to pressure.
- A knock or thump at the moment the machine starts up — The start torque twists the cabinet, and a loose foot lands.
- A sharp click every so often with nothing obviously wrong — A snap-action contact is loud on a thin-walled cabinet.
- NEAR MISS — a gurgle or a soft crackle after the compressor stops — Refrigerant settling in the liner. Normal, and no page can fix it.
Causes, most likely first on this unit
- A rear panel, drip tray or pipe is buzzing against the shell — First here because it is the cheapest noise in refrigeration and the most often mistaken for a serious one. A drip tray that has shifted, a loose rear cover or a pipe touching the cabinet turns the compressor's normal hum into a buzz that fills a room.
- The cabinet is rocking on an uneven floor — Ranked here because it is free to correct and it accounts for a large share of the noise complaints on a light cabinet.
- The thermostat and its overload clicking on each cycle — Ranked here because owners reasonably read a loud click as a fault when it is the control doing its job.
- The compressor mounting grommets have perished — Last.
Check in this order, and why
- Press each panel in turn while the machine is running — A buzz that stops under your hand is a contact noise, nothing more.
- Push the top corners and feel for rock — A cabinet that moves under a hand knocks every time the compressor starts.
- Note whether the click is followed by a run — Click then run is normal; click, pause, click is the overload.
- Listen for a low rumble that starts and stops with the compressor — A boom that tracks the run cycle is a mount, not a bearing.
What an owner can safely check
- Work out whether the noise tracks the compressor, a fan, or your hand — Three sources, three fixes, and nothing else helps until you know which.
About 10 min
- Press each outer panel while it runs and note which silences it — Then isolate the cabinet and tighten or pad that panel.
About 15 min
- Level the cabinet and wind the feet down until it cannot rock — Check all four corners, not just the two at the front.
Tools: spirit levelAbout 20 min
- Log whether each click is followed by the compressor running — That single observation separates normal from faulty.
About 15 min
- STOP HERE if the noise survives every check above — A bearing or a compressor mount means the assembly comes out. That is a service call.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never chip ice off the cold plate. The refrigerant tubing runs inside that plate and a puncture scraps the cabinet outright — let it melt instead.
When to call a technician
Call once the cabinet is level, the panels are secure and nothing loose is touching it, and a whirr, squeal or rumble is still there. That means a bearing or a mounting, and both mean the assembly comes out. Call urgently if the noise arrived with poor cooling — that is not a noise complaint at all. Call immediately if you smell burning or hear a scraping metal-on-metal sound.

What this page does not cover
This page is written for the brand and the cabinet class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer. Deliberately absent: thermostat and relay identifiers, wiring colours and capacity figures, which differ between the cube, tall compact and glass-door families.
