The short answer
Check for contact between the appliance and its housing, the worktop and the neighbouring units before suspecting a component. Check the fixing brackets and the levelling inside the housing. Most integrated refrigerator noise is transmission, not failure.
What you hear
- A hum that seems to come from the whole run — Transmission through the furniture.
- A buzz that starts and stops with the compressor — Contact at a panel or a bracket.
- A rattle behind the plinth — Tubing or debris at the condenser.
- Whirring that changes when a door opens — An internal fan.
- Gurgling after the machine stops — Refrigerant settling, and normal.
- Not this fault: noise with food warming — Read the cooling page too.
Ranked for integrated machines
- Appliance touching the housing, worktop or adjacent units — First.
- Fixing brackets over-tightened against the cabinet — Second.
- Appliance not level within its housing — Third.
- Tubing or the condenser vibrating behind the plinth — Fourth.
- Internal fan fouling frost — Fifth, and it usually comes with a cooling complaint.
- Compressor mountings hardened with age — Last.
Track it down in this order
- Press a hand on the decor panel and the worktop while it runs — A change names the path.
- Open the plinth and listen from below — It separates the condenser from the cabinet.
- Check the appliance is level inside the housing — A leaning machine rests on the furniture.
- Note whether cooling has changed as well — That separates nuisance from fault.
Owner checks
- Feel for contact between the appliance and every surrounding surface — Light contact is enough to transmit.
Tools: torchAbout 25 min
- Check the fixing brackets are snug rather than strained — Over-tightening couples machine to furniture.
Tools: screwdriverAbout 25 min
- Level the appliance within its housing — It should stand on its own feet.
Tools: spirit levelAbout 30 min
- Remove the plinth and vacuum the condenser area — It also finds rattling debris.
Tools: vacuum, torchAbout 25 min
- Note whether the sound is constant, intermittent or only on start — Each points somewhere different.
About 15 min
- Stop before working on mountings or the sealed system — Technician work in any installation.
Working on a built-in appliance
Safety
Unplug the appliance or switch off its breaker before removing any panel - locate the isolating switch first on a built-in machine, because the plug is usually unreachable. 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. Never bend or cut tubing behind the plinth, and support the appliance before loosening any bracket.
When to call
Call when there is no contact with the housing, the brackets are right, the appliance is level and a harsh or new noise remains - especially alongside a cooling change. Say the machine is integrated when booking: diagnosing noise usually means drawing it out of the housing, and that is most of the visit.

Generalized across refrigerator families under this badge, written for integrated and built-in installations; where a family-specific or model-specific page exists it is the narrower answer. Not here: sound levels, fan and compressor specifications, bracket and housing dimensions.
