The short answer for Artt ATBM
Not cooling properly on an Artt ATBM refrigerator is a failed or obstructed evaporator fan more often than it is a sealed-system or compressor fault. What moves it is the platform rather than the brand. Three of the four causes below are owner-checkable with nothing but hand tools; the rest are a service call.
What you observe on these models
- Frost has built into a sheet on the freezer rear wall — Not the usual light dusting on the ceiling, but a slab behind the rear panel where the air should come through.
- The cabinet is warm while the unit is plainly running — You can hear the compressor and feel air movement, and the food is still not cold.
- The display reads the set temperature and a thermometer inside does not agree
- The cabinet recovers overnight and loses ground during the day
- The fresh-food side is fine and the freezer is soft
- NEAR MISS — only the ice maker has stopped, and the food is cold — Cold cabinet plus no ice is an ice-maker or water-supply fault, not a cooling fault. Leave for the ice maker page.
Causes, most likely first on Artt ATBM
- A failed or obstructed evaporator fan — The fan behind the freezer rear panel is what pushes cold air into both compartments; with it stopped, the evaporator gets cold and the cabinet does not. It sits at this point because a fan blade that has caught on ice or on a stray bag stops the airflow without the motor failing at all, which is the cheapest outcome of the whole list.
- A condenser coil blanketed in dust or blocked airflow — It earns this place because a coil that cannot shed heat makes the compressor run continuously, which is the symptom owners actually notice first.
- A stalled defrost cycle icing the evaporator — Placed at this point because an adaptive defrost control fails quietly: it shortens or skips the melt rather than stopping, so the ice accumulates for a long time before the temperature moves.
- A sealed-system or compressor fault — A leak, a restriction or a compressor that no longer pumps. The unit runs, the coil never gets properly cold, and no amount of cleaning changes it. It is here because the give-away is a coil that frosts in one patch and stays dry everywhere else, or oil film on the tubing.
Check in this order, and why
- Listen at the freezer with the door held open and the switch pressed in — The evaporator fan should be audible and should stop when the door switch releases; silence with the switch held separates a fan fault from an ice fault before any panel comes off.
- Feel the condenser and check the clearance around the cabinet — Coil hot and thick with dust, or a cabinet pushed hard against the wall, explains the whole symptom without opening anything.
- Look behind the freezer rear panel for a frost slab
- Why this order and not another — It follows the ranking, not a generic checklist: on Artt ATBM the first check separates a failed or obstructed evaporator fan from a condenser coil blanketed in dust or blocked airflow, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.
Cold, sharp and still charged
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Evaporator fins are sharp and cold enough to take skin, so wear a glove for anything that reaches past them.

When to call a technician
The line is the meter. Everything above can be done by hand and by ear; the moment the next step is a resistance reading on a sensor or a voltage check at a live board, the diagnosis belongs to a technician.
