The short answer
Look for contact between the appliance and its housing before suspecting the machine. Check the levelling, the fixing brackets and whether anything touches the sides or the rear. Most integrated freezer noise is transmission through the furniture rather than a fault.
What you hear
- A hum that seems to come from the whole run of units — 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 the door opens — A fan on a frost-free machine.
- Gurgling after it stops — Refrigerant settling, and normal.
- Not this fault: noise with the cabinet warming — Read the cooling page too.
Ranked for integrated machines
- Appliance touching the housing sides, rear or worktop — First.
- Fixing brackets over-tightened against the cabinet — Second, and specific to built-in installations.
- Appliance not level inside its housing — Third.
- Tubing or the condenser vibrating behind the plinth — Fourth.
- Fan fouling frost on a frost-free machine — Fifth.
- 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 transmission path.
- Open the plinth and listen from below — It separates the condenser from the cabinet.
- Check the appliance is level within the housing — A tilted machine leans on its housing.
- Note whether cooling has changed too — That distinguishes nuisance from fault.
Owner checks
- Feel for contact between the appliance and the housing panels — Even light contact transmits vibration.
Tools: torchAbout 25 min
- Check the fixing brackets are snug rather than strained — Over-tightened brackets couple the machine to the furniture.
Tools: screwdriverAbout 25 min
- Level the appliance within its housing — It should stand on its own feet, not lean.
Tools: spirit levelAbout 30 min
- Remove the plinth and vacuum the condenser area — It also finds rattling debris.
Tools: vacuum, torchAbout 25 min
- Note when the noise occurs in the cycle — Constant, intermittent or on start are different faults.
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, since the plug behind a built-in machine is usually unreachable. A capacitor can hold a charge after the power is off. Keep a freezer at or below zero degrees Fahrenheit while you investigate. Never bend or cut tubing behind the plinth, and support the appliance before loosening any fixing bracket.
When to call
Call when there is no contact with the housing, the brackets are correct, the machine is level and a harsh or new noise persists - especially with a cooling change. Say the appliance is integrated when booking: diagnosing noise on a built-in machine usually means drawing it out of the housing, which adds time to the visit.

Generalized across freezer 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, compressor and fan specifications, bracket and housing dimensions.
