Where the sound is coming from
On the ABMO roster half the noise calls end with nothing replaced. The family covers one base number, ABMO171E, carried twice in the parts data. Levelling, a box on top, packaging never removed from the machine compartment and a fan clipping ice between them account for most of what gets reported, and none of those is a failed part.
What you actually hear
- A chirp or squeal that builds over weeks — A dry fan bearing announces itself slowly. It is loudest when the cabinet has been closed for a while and the fan is running hardest.
- A clatter for a few seconds at the start of a run — Usually the condenser fan blade catching lint or a piece of packing that has worked its way into the machine compartment.
- NEAR MISS - a loud hum with no cooling at all — That is a start-relay or compressor fault and it belongs on the cooling page for this family, not here.
What a technician expects to find
- Ice or debris contacting the evaporator fan blade — First here. The fan is inside the cold compartment, so any frost that escapes the coil area ends up in the blade path. The give-away is a noise that stops the moment the freezer door is opened and the fan is switched off.
- Evaporator or condenser fan bearing wear — Ranked here because a worn bearing is a real failure rather than an obstruction, so it does not clear itself and it does not respond to the door test. The condenser-side one is the easier of the two to reach on this roster.
- Cabinet not level or loaded against a wall — Ranked above the machine-compartment causes here because it costs nothing to check and it explains a large share of noise calls that turn out to have no failed part at all.
- Compressor or sealed-system fault — At the bottom because the probability and the cost run in opposite directions here, and acting on this entry before the ones above it is the most expensive mistake available on this page.
- Body: This ranking is about where the sound is, not what it sounds like. The brand-generic article ranks by part cost; on this roster ranking by location is more useful, because location is the one thing an owner can establish reliably.
What to check first
- Stand at the back and listen low — Machine-compartment noise is loudest at floor level behind the unit and does not change when a door is opened.
- Put a hand flat on the cabinet side while it runs — Vibration felt strongly at one side and not the other localises the source faster than listening does.
- Check the cabinet is not touching the wall or a neighbouring unit — Contact turns a normal running vibration into a drumming that reads as a failure.
- Body: The order below is set by access rather than by likelihood. On the ABMO roster everything freezer-side needs the cabinet emptied and a liner panel off, so every check that does not need that happens first.
Safety first
Safety
Switch the unit off at its breaker or unplug it before any panel comes off; a capacitor can hold a charge after the power is off. If you have to move the cabinet to reach the back, empty the doors first, protect the floor, and get help rather than walking it on its corners.
Models in the ABMO 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
The condition is simple: if the next check needs a panel off, call. Everything before that point on the ABMO listings is free, and everything after it needs the fins protected and the coil left alone. Call urgently for oil anywhere in the machine compartment.
