The short answer for the BC models
On the Advanics BC refrigerator models, a noise or a vibration that is new leads somewhere the brand-generic article does not put first — something on, in or behind the cabinet. The brand-generic ordering opens instead with this: a recess that amplifies the cabinet. It moves down behind the lead here, because this family is one model rather than a range, so the ranking can be specific where a brand-wide one has to hedge.
What you observe on these models
- A sharp crack or a pop at intervals — Plastic moving as it warms and cools, most often during or after a defrost.
- A buzz or a hum that starts with the compressor — It comes and goes with the running cycle rather than being constant.
- A rattle that appears for a minute and then stops — Something loose is being driven at one particular speed or one particular moment in the cycle.
- NEAR MISS — the noise is a hiss and you can smell something sharp — Stop, unplug and call.
Causes, most likely first on the BC family
- Something on, in or behind the cabinet — Bottles touching, a tray resting on the back wall, a drip pan out of its brackets — all free to find, free to fix, and none of them needs a tool. Ranked first on the BC models.
- A recess that amplifies the cabinet — A compact unit fitted into joinery couples every vibration it makes into the furniture around it, and a panel or a worktop is a far better sounding board than a cabinet side. Second.
- A fan blade catching ice or a stray item — The commonest source of a new, harsh noise in a working cabinet. Third.
- The compressor itself — A knocking or a labouring noise from the compressor, or a relay clicking without a start. Last, and that is the point of the order.
- Body: The spine for the BC family records a single model code, so there is no variation inside this family to hedge against: what is written here applies to the whole of it. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — something on, in or behind the cabinet — and the brand-generic lead moves down behind it.
Check in this order on the BC models, and why
- Take everything off the top and away from the sides — First: Free, instant, and it removes the commonest false alarm before you chase anything real.
- Listen at the back with the cabinet pulled out and running — Second: Distinguishes the condenser fan from the compressor, which is the split that decides whether this is owner work.
- Note whether the noise follows the running cycle — Third: A noise that starts and stops with the compressor is mechanical; one that is independent of it is usually a control or a fan.
Before you open anything
Safety
Nothing comes off this cabinet until it is unplugged or its breaker is off — the capacitor holds a charge past the switch and the fan has no warning before it starts. The sealed side is licensed work, not owner work. Deal with the food first: a refrigerator holds it safely at 40 degrees Fahrenheit, which is 4 degrees Celsius, or below, and a freezer at 0 degrees Fahrenheit.

When to call a technician
Call when the noise is a grind, a knock or a metallic scrape that has survived a defrost and a level, or when clicking comes with a cabinet that is no longer cold — both of those are behind a panel. Call immediately if you hear a hiss and smell anything sharp, or if the noise comes with a burning smell: unplug the cabinet first and make the call from there. On the BC models the line sits where the check stops being one you can make from outside the cabinet. On a unit this small the labour is most of the bill, so get the cause named before agreeing to anything — the difference between the cheap causes and the expensive one decides whether the repair is worth doing at all.
