The short answer
On the ABMQ roster the pattern that matters is which compartment warmed first. These listings feed the fresh-food side with air that has already passed the freezer coil, so a freezer that is still cold while the refrigerator section is warm is a duct or fan problem, and a cabinet that is warm throughout is something else entirely. The roster covers one base number, ABMQ171E, carried twice in the parts data.
How it presents
- Ice cream is soft but the freezer looks frozen — A freezer holding above its safe temperature still looks normal. Only a thermometer settles it.
- 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.
- 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 — Sits second on these models. Cold is being made and is not being moved, which is why the freezer can still feel acceptable while the refrigerator section is failing.
- Condenser coil or machine-compartment airflow blocked — Common in kitchens where the unit sits on carpet or in a tight surround. The fix is a vacuum, a brush and clearance, and it is the only entry here that also reduces running cost.
- Compressor, start relay or sealed-system fault — Bottom of the ranking. The tells are a compressor that is hot and silent, a relay that clicks and drops out repeatedly, or oil visible in the machine compartment. Oil outside the tubing means the system is open.
- Body: Ordered by what is found on a cabinet with this airflow layout. The evaporator fan sits high because on these listings it is inside the cold compartment, where it collects exactly the ice the defrost system was meant to remove.
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: The order below is set by the airflow path on this roster rather than by part cost. Cold is made behind the freezer liner and delivered forward, so every check moves along that path from the delivery end back towards the source.
Before a panel comes off
Safety
Isolate the unit before any panel is removed - unplug it or switch off its breaker - and a capacitor can hold a charge after the power is off. Do not run the cabinet with the liner panel off to watch the coil: the fan is unguarded once the panel is away and the fins are sharp enough to cut through a glove.
Models in the ABMQ family — The roster this page covers, taken from the model spine. Every listing in the roster shares one number series, so the access notes below hold across the roster. 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.

When to stop and call
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.
