The short answer
A new noise from the K line is a location problem before it is a parts problem. Noise from inside the freezer compartment is the evaporator fan and usually ice; noise from the back near the floor is the condenser fan or the compressor. Standing beside the cabinet and deciding which of those two it is narrows the job more than any other single step. Because only one model number carries the K name, nothing below needs a variant caveat.
What you observe on these models
- A knock at the moment the compressor starts — Perished compressor mounts, which is a noise complaint rather than a cooling one and does not threaten the cooling.
- A warbling or ticking that stops when the freezer door opens — The door switch cuts the evaporator fan, so anything that stops with the door is that fan or something touching it.
- A hum or rattle from the back near the floor — Condenser fan or compressor territory, and it continues regardless of what the doors are doing.
- A buzz that lasts half a minute and then stops — The water inlet valve filling the icemaker; it is periodic rather than constant and often mistaken for a fault.
- NEAR MISS — noise plus a cabinet that is no longer cold — Then the noise is a symptom and the cooling loss is the fault; work that page first.
Causes, most likely first on the K line
- Cabinet not level or touching the cabinetry — First, and the cheapest to rule out. A refrigerator vibrates constantly by design, and a cabinet in contact with a worktop or a neighbouring unit turns that into a drumhead.
- Condenser fan obstructed or worn — Next most likely on these models. A blade that has picked up debris rattles; a bearing that has worn whirrs and rises in pitch — two different sounds, one component.
- Evaporator fan blade meeting ice — Third — worth checking once the two above are clean. It ranks first because it is both the most common noise and an early warning that the defrost cycle is not doing its job.
Check in this order, and why
- Press a hand firmly on the top of the cabinet — If the note changes or stops, the noise is being transmitted into the furniture. Adjust the feet until the cabinet stands solid and touches nothing.
- Unplug the machine and look behind the lower rear panel — Turn the fan by hand and look for debris in the blade path. Most condenser-fan noise is something that should not be there rather than a worn motor.
- Open the freezer and listen for the sound to stop — The door switch cuts the evaporator fan. A noise that disappears the instant the door opens is that fan, and ice against the blade is the usual reason.

Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the sealed refrigerant circuit alone: it is licensed work, and a line opened by accident turns a small repair into a replacement.

When to call a technician
A noise that has no effect on cooling is rarely urgent, and on the K line it is worth working through the free checks before spending anything. The call begins at the evaporator panel: replacing that fan means emptying the freezer, removing the panel and working in frost. Call sooner if the noise is accompanied by a cabinet that is climbing in temperature.
