What is actually going on
On the K line the first suspect for a new noise is the evaporator fan behind the freezer rear panel, because this platform runs its fan close to the coil and a small build of ice reaches the blade sooner than on the brand’s other cabinets. The generic page ranks the condenser fan first; here it moves down, and the reason is clearance.
What you observe
- The noise appears only with the doors shut — Doors-shut-only noise is the interior fan by definition.
- A hum that never stops at all — A compressor that no longer cycles off runs continuously, and the constant hum is the first thing owners notice about it. On the K line this is the part that is reachable first.
- A vibration that travels through the floor — Floor transmission is a placement problem: the same machine on a solid floor is inaudible.
- A buzz that comes and goes with the ice maker — The fill valve energising against a closed supply hums. Turn the ice maker off for a day and see whether the buzz goes with it.
- A sharp crack from the cabinet at intervals — Plastic liners expand and contract as the cabinet cycles, and the crack is the liner moving against its fixings rather than anything failing.
- NEAR MISS — the noise came with a warming cabinet — Then the noise is secondary and the cooling failure is the page you want. Diagnose the temperature first.
- NEAR MISS — the sound only happens when the doors are closed hard — That is bottles and shelves settling. Rearrange the door bins before suspecting the appliance.
The causes, ranked
- A genuinely failing compressor — First — and it is not close. The least likely cause and the most expensive. Judge it by the temperature that follows the noise, never by the noise alone. Owners of the models listed in the table on this page describe this in almost identical words.
- Blocked air returns forcing the fan to work harder — Second. Restricted return air makes an ordinary fan loud. It is the one cause on this list cured by moving the shopping.
- Ice contacting the evaporator fan blade — Third. Ranked first on this platform. Frost builds where the airflow stalls, reaches the blade tip, and each rotation produces the tick owners describe as a clock. It is a defrost symptom presenting as a noise. This is where the K line differs from the brand’s other lines.
- Thermal expansion of the interior liner — Further down. The liner moves as the cabinet cycles and clicks against its fixings. It is normal and there is nothing to repair.
- Compressor mounting grommets perished with age — Fifth. Old grommets turn a normal compressor into a loud one. The sound is a resonance rather than a mechanical fault.
What to check first, second, third
- Note whether the noise is present at start-up only — The timing within the cycle is as informative as the location.
- Stand behind the machine while the compressor runs — Rear noise is condenser fan or compressor; front and interior noise is the evaporator side. Locating it halves the work. The K line puts this within reach without a teardown.
- Put a hand flat on each panel in turn — A sound that changes under your palm is a panel resonating, not a component failing.
- Switch the ice maker off for a day — If the buzz goes with it, the fill valve is the source and nothing in the cabinet needs opening.
What to do before any panel comes off
Safety
Switch the circuit off before you start, not after. A capacitor can hold a charge after the power is off, so give it a moment before working in the machine compartment. Interior door switches are part of the safety design of the cabinet and should be left wired as they are.

When this becomes a service call
Book a technician if the tick returns within weeks of a full defrost — that is a defrost control fault rather than a fan fault, and it will keep icing the blade until it is repaired. Book immediately if the machine trips its circuit when the noise happens.
