The short answer
Most noise complaints on a built-in AGA are the cabinetry amplifying a healthy machine: check the fixings, the panel and where the unit bears on the joinery. The condenser fan behind a matted front grille is second. Items resonating on glass shelves are third, and compressor mounts or the compressor itself are last.
What you observe
- The noise is heard through the worktop or the next cabinet — The joinery is carrying the vibration.
- A buzz that changes if you press the door panel — Panel fixings loose against the door.
- A whirr from behind the front grille — The condenser fan, usually against matted dust.
- Glass shelves ringing against their supports — Resonance inside the cabinet, not a fault.
- NEAR MISS — gurgling after the compressor stops — Refrigerant settling. Entirely normal.
Causes, most likely first on this brand
- Cabinetry coupling and amplifying normal vibration — First because a built-in unit is fixed into furniture by design. A fixing pulled tight against a hard contact point turns an ordinary compressor into something the whole kitchen hears.
- Condenser fan behind a matted front grille — Second: the fan lives immediately behind the only air path, so dust matting across it makes the fan work harder and sing. Cleaning the grille often halves the noise.
- Furniture panel or shelving resonating — Third, and free to find: a heavy door panel whose fixings have loosened buzzes in sympathy, and glass shelves ring against their supports.
- Compressor mounts hardened, or the compressor itself — Last. Mounts stiffen with age until the compressor speaks directly to the cabinet, and a genuine knock or growl is the one that ends the machine.
Check in this order, and why
- Press the door panel and the neighbouring cabinet — A noise that changes is being carried by joinery.
- Clean the front grille and listen again — The fan sits right behind it, and it is free to try.
- Move shelves and contents and repeat — Free, and it explains most internal ringing.
- Decide whether the noise is a knock or a hum — Left until here because a knock decides the call.
What an owner can safely check
- Press each cabinet face and the worktop while it runs — Note anywhere the noise changes or drops away.
About 20 min
- Remove and clean the front grille — Vacuum the mesh and the space behind it.
Tools: vacuum, soft brushAbout 30 min
- Check the furniture panel fixings on the door — Tighten anything that has worked loose over time.
Tools: screwdriverAbout 25 min
- Reseat glass shelves and move rattling contents — Then run the unit and listen from the same spot.
About 15 min
- STOP HERE before removing the unit from its aperture — It is heavy, fixed and connected. That is a technician job.
Before you open anything
Safety
Isolate the unit at its spur or unplug it before removing the grille or any panel; a capacitor can hold a charge after the power is off, and a built-in appliance is often fed from a socket hidden behind cabinetry. Never open a sealed refrigerant line to chase a noise, and never pull a fixed unit out of its aperture alone — these cabinets are heavy and will damage both themselves and the joinery.
When to call a technician
Call when the grille is clean, the panel is secure, the shelves are settled and a noise remains — the fan, the mounts or the compressor is then the answer, and reaching any of them means removing the unit from its aperture. Call sooner for a hard knock or a growl alongside poor cooling. Isolate the unit immediately if you smell hot insulation.

What this page does not cover
This page is written for the brand and the appliance 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 and you should start there. Deliberately absent: fixing torques, panel weights, fan and compressor part identifiers and fault-code meanings, all of which differ between the built-in column, under-counter and integrated families.
