The short answer
Most new refrigerator noises come from something touching something else, not from a failing compressor. On this machine the first suspect is evaporator fan blade catching frost or a worn fan bearing.
What you observe
- A ticking or chirping from inside the freezer — Something is touching the evaporator fan blade — usually frost.
- A buzz or hum from the bottom rear that comes and goes — The condenser fan or the compressor, and the timing tells you which.
- A rattle that stops if you press on the cabinet — Panel, tray or tubing resonance rather than a component fault.
- NEAR MISS — the noise is water running behind the panel — That is normal fill and drain, and if water is appearing on the floor the water-leak page is the right one.
Causes, most likely first on a Silhouette Pro refrigerator
- Evaporator fan blade catching frost or a worn fan bearing — A dry fan bearing whines or chirps whenever the compressor runs and goes quiet the moment it stops. Ranked first on a Silhouette Pro refrigerator: it is the noise source closest to the ear and the one owners report most.
- Condenser fan hitting dust, a bag or a stray object — A plastic bag or a dust ball against the condenser fan blade produces a loud, irregular rattle from the floor.
- Compressor mounts and ordinary running noise — A compressor hums, and on a hard floor in a quiet room that hum carries further than owners expect.
- Drain pan vibrating or sitting out of position — The pan under the cabinet collects defrost water and rattles against the frame when it is not seated.
Check in this order, and why
- Open the freezer and press the door switch in: does the noise start with the fan? — A noise that begins and ends with the fan is the fan or what it is touching.
- Pull the cabinet out and look at the fan behind the lower rear cover — Check the blade turns freely by hand with the power off.
- Note whether the noise starts and stops exactly with the compressor — Perfect correlation points at the compressor or at something resting on it.
What an owner can safely check
- Hold the door switch in and listen at the freezer rear panel, then release it and listen again — A noise that tracks the fan exactly is the fan; one that carries on is behind or below the cabinet.
About 10 min
- With the power off, clear dust and debris from around the condenser fan and coil — Most floor-level rattles stop here, and the coil cleaning helps the cooling as well.
Tools: vacuum, torchAbout 20 min
- STOP HERE if the next check needs a panel off or a meter on live terminals — That is where the owner checks end and a service call begins, whatever the ranking says.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as you found it. Never take a knife, a screwdriver or a heat gun to frost on an evaporator: the tubing behind it is thin, pressurised, and a puncture ends the appliance. Empty a loaded cabinet before you move it.
When to call a technician
Call when the noise is a grinding that worsens, when it tracks the compressor exactly and the mounts look sound, or when a fan is clearly the source and it is behind a panel. A noise alone is rarely urgent; a noise with warmth in the cabinet is. Pro-series hardware is usually serviceable and the parts are usually available, which makes a repair the right call far more often than it is on an entry compact unit.

What this page does not cover
This is the generalised Silhouette Pro refrigerator page. A family- or model-specific page, where one exists, is linked above and is the more precise answer for your unit. Left out on purpose: part numbers, connector colours, the order panels come off in, and every torque figure — a generalised page cannot be right about any of them.
