The short answer
Most new noises from the BAF line come from one of three moving parts: the evaporator fan behind the freezer wall, the condenser fan at the base, or the compressor itself. These cabinets place the first two where they can be reached, and the character of the noise tells you which one before anything is opened.
What you observe
- A rhythmic scraping or chirping from the freezer — On the models listed in the table on this page, a fan blade striking ice. It comes and goes with the cooling cycle and stops when the freezer door is opened, which is the giveaway.
- A buzz or rattle from the base at the back — The condenser fan, either out of balance or catching debris, and usually louder when the compressor has been running for a while.
- A loud hum that rises and falls with the cycle — Compressor noise transmitted into the cabinet, which is normal at low level and is a symptom when it becomes loud or changes character. The models in the table behave the same way here.
- 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.
Causes, most likely first
- An evaporator fan blade striking ice — First on the BAF 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. That holds across every model this page covers.
- 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. That is true of every model this family spans.
- Debris or imbalance at the condenser fan — The base fan draws air across the condenser and pulls in dust, paper and pet hair. A blade with debris on one side runs out of balance and buzzes under the cabinet.
- A loose drip tray or rear panel — Components that are only resting in place buzz at particular compressor speeds, which makes the noise intermittent and very hard to place by ear from across a room.
- A failing compressor — Last on this platform because it is rare and because everything above it imitates it. A compressor that is genuinely failing is also usually cooling badly, so noise on its own is weak evidence for it.
Check in this order, and why
- Open the freezer door and listen for the noise to stop — First on the BAF line because the door switch cuts the evaporator fan, so this one action isolates the most likely cause without a tool. It is the same on all the models in the table on this page.
- 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. This applies to the whole line rather than to one model.
Before you begin
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not reach behind the freezer rear panel while the cabinet is powered: the evaporator fan restarts as soon as the door switch is released.

When to call a technician
Call when the door test, the level check, the base fan and the loose panels are all clear and the noise persists. On the BAF line that points at the evaporator fan bearing or the compressor, and both are behind panels that are service work. The same is true of each model covered here.
