The short answer
A ABMB refrigerator that is warming has three cheap causes and one expensive one, and the expensive one is the least likely of the four. The roster covers four listings, ABMB141E, ABMB170E and ABMB171E, plus the starred variants of those numbers shown in the table below. That ratio is the whole reason for working down this page in order rather than starting at the compressor.
How it presents
- The cabinet cools again for a day after being emptied and left open — A strong sign of ice on the coil: the manual defrost cleared it, and the underlying reason it formed is still there.
- Condensation or sweating on the outside of the cabinet — Points at a door seal or a door left ajar, which loads the system continuously and can masquerade as a cooling fault.
- NEAR MISS - cooling is fine but the ice maker has stopped — An ice maker that has stopped while the freezer is still cold is its own fault path and has its own page for this family.
Likely causes in order
- Frost across the evaporator blocking airflow — At the top because it is the only cause here that a manual defrost will temporarily fix, and that reversibility is itself diagnostic: a cabinet that works for a day after being emptied and left open has told you where to look.
- Failed or obstructed evaporator fan — Placed at this point because the fan is the moving part in the cold space, and moving parts in cold spaces are where wear concentrates on a cabinet of this layout.
- Control, thermistor or damper fault — This is the entry that explains a cabinet where everything visible is correct. On this roster it is uncommon but it is not rare, and it is the point at which owner diagnosis usually runs out.
- Compressor, start relay or sealed-system fault — Last because refrigerant work is licensed work, the tools are not owner tools, and the probability of this being the answer is the lowest on the page.
- Body: This order is built so that the free checks come first and the licensed work comes last. On the ABMB roster that is not a compromise: the free checks are genuinely the likeliest findings, and ordering by cost happens to order by probability too.
The order to work in
- Open the freezer and look at the rear wall — A solid frost sheet rather than a light dusting is the single most informative thing visible without tools on this cabinet.
- Check the door seals and how the doors sit — Close a sheet of paper in the door and pull. If it slides out freely, the seal is not gripping and warm moist air is entering continuously.
- Body: Each step eliminates a branch rather than a part. The roster covers more than one number series, so confirm panel layout and damper position against your own rating plate before ordering anything.
Before a panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. The evaporator fins behind the freezer liner panel are sharp and thin-walled: never chip ice off them with a screwdriver or a knife, because puncturing a coil turns a defrost problem into a sealed-system replacement.

The roster carries more than one number series, so confirm the access notes below against the number on your own rating plate before you buy a part.

Where the owner line is
Call if a manual defrost restores cooling for a day and the fault then returns, because that confirms the defrost side is failing and the parts for it sit behind the liner. Call urgently if food has been above its safe temperature for an extended period, and discard anything that has been, rather than refreezing it.
