A new noise on the BKR line is worth ten minutes before it is worth a service call: on the models listed in the table on this page the door switch, the levelling feet and a hand on each panel between them identify most sounds without a tool.
What the owner actually sees
- A hard knock or clunk every few hours — Compressor start or stop, transmitted into a floor that is not flat. It is a mounting problem far more often than a compressor problem.
- A rattle that changes when the cabinet is pushed — Loose trim, a drip tray out of its lugs or a rear cover that has lost a screw. It is the cheapest fault on this list. That holds for every model the table on this page lists.
- The noise appears only with the doors shut — That points at the evaporator fan, which the door switch stops the moment either door opens.
- A ticking or scraping that stops when the freezer door opens — The door switch cuts the evaporator fan, so a noise that dies with the door open is that fan and nothing else.
- 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.
- 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.
- NEAR MISS — the noise is from the ice bin, not the machine — Ice-maker harvest noise is normal. The ice page covers what is not.
What is most likely, and why
- A dry fan bearing that is not yet failed — Ranked first on this platform. A bearing losing its lubricant squeals at start-up and quietens once warm. It will get worse, but it is not urgent. It is worth knowing that the models listed in the table on this page share this layout.
- Ice contacting the evaporator fan blade — Second, and common. A frost ridge growing toward the fan produces a rhythmic scrape that gets worse weekly. Replacing the fan without clearing the frost buys a few months at most.
- An unlevel cabinet or an uneven floor — Third. Compressor torque has to go somewhere. On an unlevel cabinet it goes into a knock, and the fix is a spanner on the front feet. On these models the panel comes away before anything else does.
- Thermal expansion of the interior liner — Further down. Expansion noise is inherent to a moulded liner and it is not a fault in any useful sense.
- Blocked air returns forcing the fan to work harder — Rarer again. Food packed against the rear wall raises the whistle and makes the fan audible in a cabinet that used to be silent. It also frosts the coil, which brings cause one along in a month or two.
What to check first, second, third
- Open the freezer door and listen — One second of listening separates the freezer fan from everything else in the machine. Do it before anything is moved.
- Note whether the noise is present at start-up only — Start-up squeals point at a drying bearing; continuous noise points at something else. The BKR line puts this within reach without a teardown.
- Put a hand flat on each panel in turn — Damping each surface by hand finds loose trim in under a minute and costs nothing.
- Listen from the next room with the kitchen quiet — Distance changes what you can hear and it separates the two classes of noise.

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 to stop and book a visit
The urgent version of this fault is a metallic knock followed by a cabinet that stops getting cold. Book that one immediately; everything else on this page can wait for a convenient appointment.
