The short answer
A compact Kalorik cabinet has no mass to absorb vibration, so a small imbalance reads as a loud buzz. Level the cabinet and check what it touches first: those two account for most noise complaints on this class. A failing fan or compressor is real but comes further down. Because these usually stand in a tight spot, the space around the unit is worth checking before anything inside it.
What you observe
- A rattle or clatter from the back or underneath — That is the condenser fan or something loose near it.
- A buzz you feel through the floor — Vibration passing into the structure rather than a failing part.
- NEAR MISS — no noise, no cold — A silent cabinet that is warm belongs on the page for a unit that will not start.
Causes, most likely first on a Kalorik refrigerator
- Cabinet not level, or touching something — Id: level — Half of what people hear is the floor rather than the appliance: a unit that rocks, or one pressed against a wall or a cabinet run, hands its vibration straight to the structure, which makes a great deal more of it. First on a compact cabinet: there is no mass to absorb vibration, so a small imbalance reads as a loud buzz. It moves up a place here because these units are installed where space is short, and short space is exactly what this fault needs.
- Compressor hum, or its mounts — Id: compressor — Second: a compressor is a pump on rubber feet. It hums while it works and it thumps as it starts and stops, and once those feet harden the thump becomes a rattle against the base.
- Condenser fan, or debris in its path — Id: condfan — Third: the fan that cools the coil is the part most likely to find something: a leaf, a bag, a pet's hair or a bearing that has run dry. All of them announce themselves from the back of the unit.
- Refrigerant and defrost noises, which are normal — Id: normalflow — Last, and the reason the order matters: some of these sounds are the machine working properly: liquid moving through narrow tubing gurgles, plastic ticks as it changes temperature, and defrost water sizzles on a warm surface.
Check in this order, and why
- Rock the cabinet and check its feet and clearances — Any movement, or any contact with a wall or unit, is the finding. First because it is the top-ranked cause above and costs nothing.
- Put a hand on the compressor housing as it runs — A knock you can feel is mounting; a hum you can only hear is normal. Second because its cause ranks second above.
- Look at the fan behind or under the cabinet with the power off — Debris in the blade path shows itself immediately. Third because its cause ranks third above.
What an owner can safely check
- Name the sound and when it happens — Continuous, cyclic, or only at start-up — this alone narrows it to one or two causes.
About 10 min
- Restore the clearance the manual asks for and retest — Pull it out, leave the gap, and give it a day before judging.
About 25 min
- Switch the power off and clear the condenser fan area — Remove debris from the blade path and vacuum the coil while you are there.
Tools: vacuum, flashlightAbout 20 min
- STOP HERE if the next step needs a panel off with power on — Fan and compressor work behind a live panel is a service call.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before reaching behind any panel or near a fan — a capacitor can hold a charge after the power is off, and a fan can start without warning. Never hold a blade to stop it. Leave the door switch alone; it is what makes the fan test meaningful. Get help before moving a tall cabinet.
When to call a technician
Call when the noise is mechanical and constant after the cabinet has been levelled, cleared and cleaned — a worn fan bearing or a compressor mount is a parts job rather than an adjustment. Call sooner if the noise arrived with a loss of cooling, because then it is a symptom rather than a nuisance. Parts come from the seller, and on a cabinet this size a sealed-system repair usually costs more than replacement.

What this page does not cover
This page covers Kalorik refrigerators as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer. Not here: part numbers, fan ratings and mount specifications. It is small counter-standing cabinets sold as housewares rather than as kitchen appliances.
