The short answer
A ABMH refrigerator gets noisy in one of three places and no others: behind the freezer liner, low at the back, or through its own feet into the floor. The roster covers one base number, ABMH171E, carried twice in the parts data. Standing in each of the three for a minute is a better diagnosis than any description of the sound.
How it presents
- A buzz or rattle that stops when the freezer door is opened — The freezer-side fan is switched by the door, so the door itself is a free diagnostic. This one tell separates the two likeliest causes before any tool comes out.
- Vibration you can feel through the door handle — The cabinet is transmitting rather than generating. Look at levelling and at whether anything is stacked against the sides.
- NEAR MISS - water noise plus water on the floor — A noise with a puddle is a drain or fill problem. Read the water-leak page for this family instead.
Causes in the order they turn up
- Ice or debris contacting the evaporator fan blade — Ranked at the top on this roster because the fan sits behind the freezer liner where nothing is visible until the panel comes off. Frost creeps out from the coil, the blade tip starts clipping it, and the owner hears a growl that seems to come from the whole appliance.
- Lint or packing debris in the machine compartment — At this point in the list because it produces a short clatter at the start of a run rather than a continuous noise, and that timing is what separates it from the entries above.
- Hardened compressor mounting grommets — Here because it is a change in what you hear rather than a change in what the cabinet does, and because no part fitted will make a twenty-year-old isolator young again.
- Compressor or sealed-system fault — Ranked last because it is both the least common finding and the most expensive, which is exactly the combination that makes a wrong guess costly. Get the cause named before deciding anything.
- Body: Ranked by what a technician finds, cheapest-to-confirm first where two causes are genuinely close. The only reordering against the brand-generic page is that ice contact sits above bearing wear here, because on this roster the fan runs inside the cold compartment rather than outside it.
Where to stand, in what order
- Check the unit is sitting on all its feet — Press each corner in turn. A cabinet that rocks is amplifying every internal vibration into the floor.
- Note whether the noise is constant or in bursts — Constant points at a bearing; bursts at the start of a run point at an obstruction that clears itself.
- Body: Work down this list rather than across it. The first two checks cost nothing and between them they resolve most noise calls on this cabinet type without a single panel being removed.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. The freezer-side fan here starts on a door switch, not on a control decision, so holding the switch in to watch the blade turn is exactly the thing not to do. A capacitor can hold a charge after the power is off.
Models in the ABMH family — This page generalizes over every listing in the roster below; where the models diverge for this fault the text says so, and where it does not, they behave alike. A starred entry in the table is the same base number recorded a second way in the parts data; treat it as the same platform for this fault unless your own parts diagram says otherwise.

Where the owner line is
Anything that needs the sealed system opened is a service call by law, not by preference. On this roster that is the last entry in the ranking only, so most noise calls end well before that point. Call sooner if you see oil anywhere in the machine compartment, because oil outside the tubing means the system is open.
