What this means on this family
On the ATMA refrigerator family a cabinet that runs but will not hold temperature is far more often an airflow problem than a dead compressor. This family is a short list of model numbers rather than a whole range. The first two checks below need no tools and no panel off; only the last of the ranked causes is a sealed-system job.
What an owner actually sees
- A frost sheet on the back wall of the freezer compartment — Not the usual light dusting but a solid layer. Frost that thick blocks the path air has to take, so the cabinet warms while the unit runs harder.
- The unit never cycles off — A compressor that runs without a break is a compressor that never reaches its cut-out point. Continuous running is the same fault seen from the control side.
- Condensation or sweating around the door opening — Warm, damp air is being pulled in past a seal. It rarely causes the warm cabinet alone, but it makes every other cause worse.
- NEAR MISS — water pooling under the crisper with normal temperatures — That is a blocked defrost drain, covered on the water-leak page for this family, not a cooling failure.
What to suspect, in order, on this family
- Start relay and overload at the compressor — First on the ATMA refrigerator family. A start device that is failing intermittently lets the compressor start, run briefly and drop out on its overload, so the owner hears a machine that is clearly working and finds a cabinet that never gets there.
- Thermostat or control board — Second, because a control that satisfies too early produces exactly this complaint and leaves no other trace — no frost, no noise, no smell.
- Condenser airflow and dust — Third. It is the cause that turns a machine which was coping into one which is not, and it shows up first in warm weather.
- The seal and how the cabinet is packed — Fourth, and it belongs on the list because it is the cause an owner can fix in the time it takes to repack the shelves.
- Refrigerant loss or a restricted sealed system — Last, by elimination only. A slow loss shows as a cabinet that cools a little and a compressor that never stops, but so do three cheaper causes above it — so it should be the conclusion of a diagnosis, never its opening guess.
Check in this order, and why
- Confirm the compressor is actually running — Everything below assumes it is. A silent cabinet is a different fault and a different page.
- Look for frost on the rear wall of the freezer section — A sheet rather than a dusting confirms the airflow cause before any tool comes out.
- Check the seal with a sheet of paper all round the door — If it pulls out easily at any point, that corner is your leak.
- Feel the condenser and the space around the cabinet — Done last because it is the slowest to matter and the easiest to misread on a machine that has been running hot all day.
Safety first
Safety
Before a panel comes off, unplug the appliance or switch off its breaker; a capacitor can hold a charge after the power is off. Leave the door switch wired as it is: it cuts power to the internal fan for a reason, and defeating it puts a moving blade in reach of a hand. Anything on the sealed system is licensed work; do not open refrigerant tubing. While the cabinet is warm, treat the food by the clock rather than by the look of it: a refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below. Above those, move anything perishable to a cooler with ice and keep the door shut.

When to call a technician
Call when the cabinet has been checked from the outside and is still warm, or the moment the fault is on the sealed system. A technician will want to know three things you can collect for nothing: whether the compressor runs steadily, whether air moves at the vent, and whether there is ice at the back of the freezer section.
