What this means on this line
On the BFBD line the freezer door switch cuts the evaporator fan, which hands an owner a free isolating test that no other appliance offers. Use it before anything else, because it eliminates the most likely cause in one action.
Symptoms on these models
- The noise started after a large shop — For every model in this family, bottles and jars resonate against each other and against the liner, and a surprising share of reported noises are the contents.
- A hum that has grown louder over months — A change in level rather than in character, which usually tracks a condenser that is progressively more matted.
- The noise is worse in hot weather — Longer run times in warm ambient mean more hours of whatever is making the sound, which makes an old noise suddenly noticeable. It does not vary across the models listed on this page.
- NEAR MISS: the noise arrives with a warm compartment — Then the noise is secondary and the cooling-failure page for this family is the right one to work from.
Why it happens, in order
- An evaporator fan blade striking ice — First on the BFBD line because the fan sits close behind the freezer rear panel with little clearance, so even a modest frost build brings ice into contact with the blade and produces the classic intermittent scrape. This applies to the whole line rather than to one model.
- A cabinet that is not level or not stable — Second because it is free to fix and very common after a floor is laid or the appliance is moved. A cabinet rocking on three feet transmits every normal vibration into the room. The same is true of each model covered here.
- Hardened compressor mountings — Rubber mounts stiffen with age and stop absorbing the start surge, so a normal compressor transmits a knock into the cabinet that it did not transmit when new.
- The cabinet touching a wall, a pipe or a unit — A refrigerator pressed against a surface transmits its normal vibration into the building, which amplifies a sound that would be inaudible with an inch of clearance.
- A condenser fan motor bearing — Last because it is uncommon and because dust and imbalance produce the same buzz far more often. It is distinguished by being constant and unaffected by cleaning.
What to check first, second, third
- Open the freezer door and listen for the noise to stop — First on the BFBD line because the door switch cuts the evaporator fan, so this one action isolates the most likely cause without a tool. The models in the table behave the same way here.
- Put an ear to the base at the back of the cabinet — Second: the condenser fan and the compressor both live there and they sound entirely different, one a buzz and the other a hum.
- Rock the cabinet gently with both hands — Third, because a cabinet that moves is a cabinet that rattles, and levelling it takes a spanner and two minutes. That is true of every model this family spans.
Before anything comes apart
Safety
Isolate the cabinet before working at the base. Never clear ice from a coil with a sharp tool or a heat gun, because the tubing is thin-walled and a puncture ends the appliance.

When this becomes a service call
The owner boundary on the BFBD line is the freezer rear panel and the base cover. Everything outside them is free to check; everything inside them is service work. That holds across every model this page covers.
