Start here
The short answer: expect evaporator fan chopping at frost, and expect the fix to be free. Refrigerators hum, tick and gurgle as part of normal operation, so the first job is separating a sound that has changed from a sound that was always there.
What the refrigerator is actually doing
- A hum that has become a harsh buzz at the back — Compressor noise that has changed character is worth attention even when the cabinet is still cold.
- Clicking every few minutes with no cooling change — A start relay or a control clicking through its cycle. Regular and quiet is normal; repeated clicking with warming is not.
- A grinding sound from the base while it is running — The condenser fan is at the base and pulls in dust, paper and whatever lives under the cabinet.
- NEAR MISS — it is noisy and the cabinet is also warming up — Noise plus a loss of cooling is a cooling fault first. Read the cooling page: temperature outranks sound as a symptom.
The ranking, and why it is this way round
- Evaporator fan chopping at frost — Two fans run in a refrigerator and both make noise when something reaches them. The evaporator fan behind the freezer panel hits frost when a defrost cycle stalls; the condenser fan at the base pulls in dust, wrappers and pet hair from the floor. Ranked ahead of the rest since it is both the likeliest and the only one that can be settled before anything is taken apart. On a badge this size the parts channel is thin, so the ranking is written around what can be checked and corrected without a part on order.
- Vibration transmitted into the floor or the units beside it — This cause is at once the most common source of new noise and the cheapest to fix, because nothing has failed. A cabinet that has been pulled out for cleaning and pushed back slightly differently will often start buzzing for exactly this reason. Second, and worth checking before anything is taken apart, since it is visible from outside the cabinet.
- Icemaker noises mistaken for a fault — An icemaker runs on its own schedule, so its noises arrive when nothing else is happening and sound far more significant than they are. It ranks here because it is genuinely less common, not because it matters less when it happens.
- Start relay clicking at the back — A compressor hums while it runs and clicks as it starts and stops, and both are normal. What is not normal is a hum that has turned harsh, or a click every few minutes with the cabinet warming — that is a start device failing to bring the motor up. Last, and deliberately so — it should be where a diagnosis ends rather than where it starts.
Check in this order, and why
- Open the freezer, press the door switch in, and listen for the fan — A chopping or whirring that follows the switch is the evaporator fan, and it points at ice or an obstruction rather than the motor. Begin with this one; everything after it depends on what you find.
- Rock the cabinet gently front to back and check each foot touches — One foot short of the floor turns the whole cabinet into a sounding box. Second, once the first check is clean.
- Lift the bail arm or switch the icemaker off, and listen for a day — If the noise disappears with the icemaker off, you have found it and nothing is broken. Third, and the last thing worth doing before the phone comes out.
What to do, step by step
- Vacuum the base grille area and the visible fan blade — Do it with the power off, and do not push anything rigid through the grille.
Tools: vacuum, torchAbout 20 min
- Adjust the levelling feet until the cabinet sits firm and tilts very slightly back — A slight backward tilt also helps the doors close on their own.
Tools: adjustable spanner, spirit levelAbout 25 min
- Empty the ice bin, check for a jam, and refit it squarely — A bin that is not seated will rattle against the auger every time it turns.
About 15 min
- STOP as soon as the fault is narrowed to a part rather than a condition — Naming the part is the useful outcome of an owner check. Fitting it is the other half, and it is not the same job.
Before you touch anything
Safety
Switch the power off at the plug or the breaker before anything comes apart, and leave it off while you work. A refrigerator carries a capacitor that holds a charge after the power is off, and the door switch is there to cut the fan for a reason — never defeat it to keep the light or the fan running while your hands are inside.
When to stop and call
Book a visit only after the cabinet has been levelled, the vents cleared and the icemaker ruled out. Those three cost nothing and between them they explain most of what gets reported as a failing refrigerator.

What this page does not cover
This page covers KovaSelect refrigerators as a class, not one family or one model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and the one to read first. Deliberately not here: wiring colours, torque figures and part numbers, all of which differ by family.
