The short answer for these models
Warm cabinet, compressor audibly running: on the ARB refrigerator family that combination narrows the field immediately. This family is one model number, which makes the scope of this page unusually clear. The ranking below is set by how these cabinets are built, and it differs from the generic order in which cause sits first.
The observations that separate this fault from its neighbours
- 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.
- Warm air at the vent when you hold a hand in front of it — Air moving but not cold means the evaporator is not taking heat out; no air at all means it is blocked or the fan has stopped.
- The freezer section holds but the fresh-food section does not — Cold is being made and is not reaching the upper cabinet — an airflow split, not a cooling failure, and it points straight at the vent path.
- NEAR MISS — the cabinet is silent and nothing is cold — Silence changes the question entirely: that is a no-power, start-device or control fault, and it belongs on a different page.
Causes, most likely first on the ARB line
- Start relay and overload at the compressor — Ranked first here because the pattern the owner describes — runs, stops, tries again — is the classic signature of a start relay on its way out rather than of anything in the air path.
- The temperature control — 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. Worth doing early because it costs nothing but a vacuum and a few minutes.
- The seal and how the cabinet is packed — Fourth. Overloading blocks the internal vents on cabinets of this size, and a seal that leaks adds moisture that ends up as frost. Neither usually causes the failure alone, but both make a marginal cabinet fail.
- 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
- Listen for the pattern rather than the presence of running — Steady running, a click every few minutes, or short bursts — the pattern names the suspect before anything is opened.
- Put a thermometer in the cabinet and leave it — What the cabinet holds is the measurement that matters; the dial setting is only what it was asked to hold.
- Clear and inspect the condenser and its airflow — Cheap, quick, and it removes the most common environmental cause from the list.
- Stop at the sealed system — Anything past this point is licensed work, and the diagnosis above is what a technician will want to hear first.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel — 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. A refrigerator holds food safely at 40 °F (4 °C) or below, and a freezer at 0 °F (−18 °C) or below. If the cabinet has been above that and you do not know for how long, the safe assumption is the worst one. Keep the door closed while you work — every opening costs cold you cannot put back quickly.

The line between an owner fix and a service call
The line on these models sits where the tools change. Adjusting a seal, clearing vents and cleaning a condenser need nothing a household does not have; testing a fan motor, a defrost heater or a control board needs a meter and the cabinet open, and refrigerant work needs a licence. Call sooner rather than later if the cabinet is above safe temperature, because food loss usually costs more than the diagnosis.
