What this usually is
On the F family, a cabinet that has started making a noise it did not make before usually comes down to tubing. The first check that pays is this one: with the unit running, press lightly on each rear panel and the drain pan.
The symptoms, including the ones that mean something else
- A vibration through the floor rather than through the air — A cabinet whose feet are not carrying it evenly transmits the compressor straight into the floorboards.
- A new noise that arrived after the unit was moved — Moving a cabinet changes what is touching what, which is why so many noise complaints start the week after a kitchen is rearranged.
- A buzz or drone that comes and goes with the compressor — It starts when the cooling starts and stops when it stops, which places it at the compressor deck rather than inside the cabinet.
- NEAR MISS: noise from the ice maker only when it fills — Filling and dropping noises on a cycle are normal, and the ice maker page covers what they should sound like.
Causes in order of likelihood here
- Tubing, drain pan or panel touching something it should not — It sits where it does rather than at the top because it takes a look behind the cabinet to confirm, but it is the cause that most reliably explains a rattle that changes when you touch the panel.
- Cabinet not sitting level or not carrying weight evenly — It ranks second because it is the most common cause and the cheapest to rule out: a cabinet with one foot short transmits every compressor vibration into the floor instead of absorbing it.
- Evaporator fan blade catching ice — It ranks here on a fan-cooled cabinet because it is the noise that matters: left alone, the same ice that the blade is hitting will take the cooling with it within weeks.
- Compressor mounts hardened or the compressor itself noisy — A compressor that has genuinely become noisy internally is uncommon, which is why it sits here and not at the top no matter how much the noise seems to come from it.
- Body: The table below shows what the F family actually is: the same cabinets listed repeatedly in different finishes, with the numeric part of the model number separating the sizes. Finish does not change how a cabinet fails, so the useful differences across this list are size and age rather than specification.
The diagnostic order
- With the unit running, press lightly on each rear panel and the drain pan — A noise that changes or stops under a hand is a contact point, and it is almost always fixable without parts.
- Rock the cabinet gently at each front corner — Any movement at all means a foot is not carrying, and that is where the noise is coming from.
- Open the freezer and listen with the door switch held in — A chopping that starts with the fan and stops when you release the switch places the noise at the blade.
- Body: The order follows the ranking above rather than the layout of the cabinet: each check either confirms the cause above it or removes it, and they are arranged so that the free checks come before anything that needs the unit moved or a panel off. Access is the same across the models in the table, so the order holds for all of them.
Before any panel comes off
Safety
Power off first, every time a panel or a grille is involved, and leave it off rather than switching back to listen. The fan blades in this cabinet start on a control signal, not on a schedule you can predict.

When this becomes a service call
Call if the noise is rhythmic and inside the freezer and comes back within days of a full defrost, because that is a defrost system falling behind rather than a simple blade contact, and the cooling will follow it down. Call also for any noise that is getting steadily louder week by week rather than staying the same.
