The short answer
On the BCD family the noise complaint is usually structural: a cabinet that is not sitting still, or a compressor whose mounts have gone hard. Light cabinets on hard floors transmit everything, so the same compressor that is inaudible in one kitchen fills the next one. Rule the installation out before suspecting a part.
What you observe on these models
- A buzz or rattle that comes and goes with the compressor — It starts when the machine starts and stops when it stops, which places it at the compressor end rather than inside the cabinet.
- A ticking or clicking every few seconds — Short, repeated and always at the same interval: that is a start device cycling, not a mechanical noise.
- A fan noise that changes when the door is opened — If it stops with the door switch it is the evaporator fan inside; if it carries on it is at the back of the cabinet.
- NEAR MISS - a loud noise with the cabinet also going warm — Noise plus a loss of cooling is not a noise complaint.
Causes, most likely first on this family
- Cabinet rocking, or in contact with a wall or a cupboard — First on this family. A light cabinet with adjustable feet on a tiled or laminate floor amplifies normal compressor vibration into a drumming that owners reasonably describe as a fault, and on a single-model family there is no configuration question to settle first.
- Hardened compressor mounts — Second. The rubber grommets under the compressor go hard with age and heat, and the compressor then transmits its own vibration straight into the shell.
- Loose rear cover, drip tray or tubing contact — Third. A rear panel with a missing screw buzzes at one particular compressor speed, and a suction line touching the cabinet wall transmits the same way. Both are found by hand, not by ear.
- Fans and the compressor itself — Last. A fan bearing or a failing compressor does make noise here, but on this family they sit behind the three structural causes above, and checking them first wastes an afternoon.
Check in this order, and why this family dictates it
- Push the cabinet gently at the top corners while it runs — If the noise changes as you take the weight, the installation is the fault and nothing needs opening.
- Check the clearance at the back and the sides — Second because it follows from the first and it is common to find a cabinet pushed into contact with a wall or a pipe.
- Press a hand flat on the rear cover while the noise is happening — Third: a buzz that stops under hand pressure is a panel or a clip, not a bearing.
- Then isolate fan from compressor with the door-switch test — Last, and only now: this is where the parts start, so it is worth being sure the first three are clean.
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 reach behind a running fan to find a noise, and never run the cabinet with its rear cover off to listen: the cover is part of the airflow path and it is also what keeps fingers out of the fan.

When to call a technician
Call when the noise is a knock or a grind at the compressor, when a fan noise continues after the obstruction and the frost have been dealt with, or when the noise arrives alongside a loss of cooling. Give the technician the model number from the table above so the correct fan or mount kit arrives with them.
