The short answer
Level the cabinet on all its feet, pull it clear of walls and units, and take anything stored on top off. Then listen for whether the sound tracks the compressor or a fan. Most free-standing noise ends with those three checks.
What you hear
- A drone that fills an open-plan room — Reflection plus a cabinet touching something.
- Rocking or a thud on start — The cabinet is not level.
- Rattling against a unit or a wall — Direct contact.
- Whirring that changes with a door — An internal fan.
- A rattle from underneath — Debris or a drip tray.
- Not this fault: intermittent humming with normal cooling — Ordinary cycling.
Ranked for free-standing and under-counter machines
- Cabinet not level or rocking on the floor — First.
- Cabinet touching a wall, unit or worktop — Second.
- Items stored on top resonating — Third, and free to fix.
- Drip tray or debris underneath — Fourth.
- Internal fan fouling frost — Fifth.
- Compressor mountings or the compressor itself — Last, and it comes with reduced cooling.
Work through it in this order
- Rock the cabinet by hand with the machine off — Any movement is the first thing to fix.
- Pull it clear of every surrounding surface — Contact is what carries the sound.
- Clear the top of the machine — Boxes and trays buzz in sympathy.
- Listen from a distance to separate machine from room — Reflection exaggerates everything.
Owner checks
- Level the cabinet on all its feet — A single unloaded foot causes a rocking machine.

Moving a loaded appliance
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Keep the refrigerator at or below forty degrees Fahrenheit and the freezer at or below zero degrees Fahrenheit while you investigate. A loaded refrigerator is heavy - empty it before moving it on a hard floor, and never bend or cut tubing at the rear.
When to call
Call when the cabinet is level and free-standing, nothing is stored on it, the underside is clear and a harsh noise persists - especially with a cooling change. On an under-counter or drinks cabinet, mention the installation, because even a free-standing machine in a fitted run may need the surrounding units eased to get it out.
