The short answer
On the Black Decker BCFB refrigerator an unfamiliar noise is usually a fan working against something it should not be touching. BCFB is a single build, so the checks below hold for every model in the table and the fastest of them need no tools at all.
What you observe
- A buzz or drone that comes through the floor — Loudest in the room next door or in a cupboard, quieter beside the cabinet itself.
- A rattle that starts and stops with the compressor — Something loose is being shaken by a part that is behaving perfectly.
- A whirr, chirp or scrape that stops when the door opens — That is the cabinet fan, and a fan that only complains under load is either touching ice or running on a worn bearing.
- NEAR MISS — noise with a cabinet that is also warming — Then the noise is a symptom of the cooling fault, not the complaint.
Causes, most likely first on the BCFB family
- A fan blade catching ice, a wire or packaging — First on this family — BCFB is a single build — and the fan sits in the coldest, tightest part of the cabinet where frost grows and a bag can be pushed against the grille. It produces the chirp-scrape most owners describe as a bird in the kitchen.
- Fan bearing wear — Second. Same location, different sound: a steady whirr that rises with running time and does not change when the cabinet is moved. On a unit that has run for years it is the most common part to actually fail.
- Loose trays, shelves and the drip pan — Third — the cheapest and most frequently missed. A drip pan resting slightly off its rails or a bottle standing on a shelf against the back wall turns compressor vibration into a rattle the moment the cycle starts.
- Compressor mounts and levelling — Last here, because a drone that comes through the floor is a transmission problem rather than a fault, and it behaves differently: it does not change when the door opens, only when the cabinet moves.
Check in this order, and why
- Open the door while the noise is happening — On builds with a cabinet fan it usually stops with the door.
- Empty the compartment nearest the noise and run it again — Second because packaging against a grille is free to rule out and is the single most common find behind a fan complaint.
- Look for a frost sheet where the fan runs — Third: ice on the coil and a scraping fan are one fault, not two, and fixing the fan alone puts the machine straight back where it was.
- Rock the cabinet and pull it off the wall — Last.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Keep fingers clear of a fan that may restart on its own when a door closes or a timer advances, and never run the cabinet with a fan shroud removed.

When to call a technician
Call when the noise is steady, rises with running time and ignores everything you change — that pattern is bearing wear, and it does not improve. Call immediately if the noise arrives with a burning smell, with a cabinet that is also warming, or with a compressor that clicks in and out every few minutes; at that point the noise is the least interesting thing happening.
