The short answer
A refrigerator noise is almost always a moving part touching something it should not, and the useful question is not how loud it is but when it happens. A sound tied to the compressor cycle, a sound tied to opening the door, and a sound that never stops are three different faults with three different answers. On a Ricci refrigerator the cause that ranks first is something touching a fan blade.
What you observe
- A buzz or rattle that starts and stops with the cooling cycle — Machine-compartment noise: condenser fan, compressor mounts, or something resting against the cabinet back.
- A whirring or chirping that stops when the freezer door opens — The evaporator fan, because the door switch cuts its power.
- NEAR MISS — a click every few minutes with no cooling at all — That is a start relay cycling on its overload, and it belongs on the not-cooling page.
Causes, most likely first on a Ricci refrigerator
- Something touching a fan blade — Ice on the evaporator blade, or debris and packaging against the condenser fan, produces a ticking or chirping that changes with the fan speed. Ranked first on this refrigerator, because it is the most common cause of a new noise and costs nothing to find.
- Cabinet not level or touching the surround — A cabinet resting on a cupboard side transmits ordinary compressor vibration into the furniture, which amplifies it.
- Evaporator fan blade striking frost — As ice builds behind the freezer panel it eventually reaches the blade.
- Compressor mounts hardened or a loose panel — Rubber mounts harden with age; a loose rear panel or drip tray buzzes in sympathy with the compressor.
Check in this order, and why
- Note whether the noise changes pitch or stops when you open the freezer door — This single observation separates the two fans and removes most of the list.
- Rock the cabinet gently and check whether it touches the surround — A cabinet that moves or contacts furniture is amplifying an ordinary sound.
- Look behind the freezer rear panel for frost reaching the fan blade — If ice is on the blade, the noise and a coming cooling fault have the same cause.
What an owner can safely check
- Open the freezer with the cabinet running and note whether the noise stops — Let the door swing; do not wedge the switch.
About 5 min
- Level the cabinet and make sure it is not resting against furniture on any side — Adjust the feet until it sits square with clearance on both sides.
Tools: spirit level, spannerAbout 15 min
- Empty the freezer, switch off and let the cabinet defrost fully with the doors open — If the noise is gone afterwards and returns over days, the defrost system is the real fault.
About 45 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins, whatever the ranking above says.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before reaching into the machine compartment or removing any panel — a capacitor can hold a charge after the power is off, and a condenser fan can start without warning. Never put a hand near a running fan to test it. Do not wedge the freezer door switch closed to keep the fan running; open the door and listen instead. Never cut or open a sealed-system line.
When to call a technician
Call when the noise is still there after the fan path, the stance and the fasteners are clear, or when the noise arrives with a cooling fault — the combination usually means the evaporator is icing and the defrost system is at fault. Call immediately for a grinding or screeching from the machine compartment, or a loud hum with no cooling at all: both of those are starting or compressor conditions, and continuing to run the cabinet makes them worse.

What this page does not cover
This page is written for the Ricci refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is linked above, it is the more specific answer, and it is the one to read first. Deliberately not here: part numbers, wiring colours, panel removal order and torque figures, which differ between families under the same nameplate.
