What this usually means
For a ARBM unit: the machine can run continuously and still lose ground. The usual reason is an evaporator sheeted in ice, which stops the fan from pushing air over it; the cabinet then warms even though the compressor never stops trying. That is the same list the brand-generic page carries, in a different order.
What you observe on a ARBM unit
- Food in the door is spoiling faster than food at the back — The door shelves are the warmest place in a cabinet that is losing its set point, so they fail first. This is the ARBM tell that separates the branches.
- The interior light is on and the panel responds normally — Power and control are fine; this is a cooling fault, not an electrical dead unit.
- Bottles in the door are cool while the back of the shelf is warm — Reversed from the usual pattern, and it points at air distribution rather than at cooling capacity.
- NEAR MISS: the cabinet is cold but there is water on the floor — A unit that still cools while it leaks is a drain or supply-line problem, not this.
The ranking on the ARBM line
- Airflow blocked by a frosted evaporator — Ranked first because it builds slowly and quietly: the defrost cycle stalls before it fails outright, ice sheets over the coil for weeks, and the owner notices the warmth long before the frost. On a ARBM unit this is still the first thing to eliminate.
- A door seal that no longer seals — A gasket that has gone hard or has torn at a corner admits room air all day. The compressor runs longer and longer against a load it cannot win.
- A sealed-system or compressor fault — Last, and that ranking is the point of this page: it is the least likely cause on the list and the only one that is not an owner check. Anyone naming it first has skipped every cheaper answer above it.
What to check first, second, third
- Open the freezer and listen for the circulating fan — It separates the two likeliest causes before a single tool comes out: a fan you can hear rules out the stopped-motor branch. The ARBM layout is the reason it comes first here.
- Check whether the fresh-food vent is blocked by packed food — Boxes stacked against the vent starve the compartment as effectively as a broken damper, and cost nothing to move.
- Look for water or ice under the crisper drawers — That is melt from above, and it confirms the evaporator has been icing rather than cooling.
What to do before you start
Safety
Unplug the appliance or switch off its breaker before a panel comes off and leave it isolated while you work; stored charge outlives the switch. Do not attempt anything on the sealed system — the tubing is pressurised and refrigerant is licensed work. If a compressor is hot enough to be uncomfortable to touch, give it time before reaching past it.

When to stop and call
Call when the visible causes are all clean and the cabinet still will not hold. A thermistor, a defrost component or the sealed system are each diagnosed with tools an owner does not have. Call the same day if the compressor is running continuously and is uncomfortably hot to the touch.
