The short answer for Artt ATTM
The Artt ATTM family answers this differently from the brand as a whole: here door seals or a door that is not closing square ranks ahead of a sealed-system or compressor fault, because of how these models are built and how they are reached. Of the four causes ranked below, three are owner work and the remainder need a technician.
What you observe on these models
- The back of the cabinet is hot and the room smells warm — A condenser that cannot shed its heat makes the whole kitchen corner warm.
- The cabinet recovers overnight and loses ground during the day — A cabinet that is only marginal is telling you about its load and its sealing rather than about a failed part.
- 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 ATTM
- Door seals or a door that is not closing square — Warm room air leaking past a tired gasket loads the system continuously and frosts the evaporator faster than the defrost cycle can clear it. Placed at this point because a cabinet that is not level lets the door hang out of square, so the seal fails along one edge only and the owner never sees a gap.
- A failed or obstructed evaporator fan — It is here 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 stalled defrost cycle icing the evaporator — Ranked here 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 sits at this point because refrigerant work is licensed work, so there is nothing an owner can usefully do here beyond describing the symptom accurately.
Check in this order, and why
- Close the door on a sheet of paper at several points around the frame — Paper that slides out with no drag has found a leak, and a leak explains warming and frosting together.
- 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.
- Why this order and not another — It follows the ranking, not a generic checklist: on Artt ATTM the first check separates door seals or a door that is not closing square from a failed or obstructed evaporator fan, and access decides the rest — what this family puts behind which panel is why the cheap check comes first.
Power off first, and what not to defeat
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. On a cold cabinet the parts that bite are behind the lower rear access panel, where the start relay and the run capacitor live, and behind the interior rear panel, where a defrost heater sits in the airflow.

When to call a technician
The condition for calling is simple: a cabinet that has had a clean condenser, a tested door seal, a confirmed interior fan and a full manual defrost, and still cannot hold temperature the following day. Anything short of that list and the free checks are still worth doing.
