The short answer
On the Arieta ARWS refrigerator line, a cabinet that is not cooling is worth working through in a set order: thermostat, sensor or control settings first, then door seals, over-packing and blocked internal vents, and only after those does the sealed system enter the picture. That order is written for a single-model line and sequenced for how these models are put together, which is where it departs from the brand-generic article.
What you observe
- The cabinet is cold but not cold enough, and has been steady that way — A small constant error points at a setting or a sensor rather than at airflow.
- The fresh-food side is warm while the freezer is still cold — A split like that is nearly always air movement between the compartments rather than cooling itself.
- NEAR MISS — the freezer is fine and only the ice maker has stopped — That is an ice production fault; the cooling system is doing its job.
Causes, most likely first on the ARWS line
- Thermostat, sensor or control settings — The first thing to suspect: a control that has been nudged, a sensor reading warm or a cabinet left in demo mode after a store display will hold the machine at the wrong temperature with nothing mechanically wrong at all, and it is the cheapest of these to rule out.
- Door seals, over-packing and blocked internal vents — Seals and airflow are checked early because they cost nothing and they produce the same symptom as an expensive fault.
- A dust-blanketed condenser coil, or a condenser fan that has stopped — A dirty coil or a stopped condenser fan produces a cabinet that never quite reaches temperature, and both are visible from the back.
- A stalled defrost cycle icing up the evaporator — The defrost system is the answer when everything else is clean and cold is simply not arriving where it should.
- Sealed system, compressor or start components — Last here, and the only cause on this list that is not owner work — a sealed-system or compressor fault means the machine cannot make cold at all, and refrigerant work is licensed work with tools that are not owner tools.
Check in this order, and why
- Read the setting, then measure the actual temperature with a glass of water and a thermometer — A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below. Done first because it separates the likeliest causes before any tool is needed.
- Close the door on a sheet of paper and pull — Second: it confirms or dismisses what the first check suggested.
- Unplug the unit and look at the condenser coil and fan at the back or underneath — Third, once the two checks above are clean.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. While the cabinet is warm, treat the food as the priority: a refrigerator holds food safely at 40 °F (4 °C) or below, so move anything perishable into a cooler with ice before you start work rather than after.

When to call a technician
Call when the seals, the vents, the coil and a full defrost have all been done and the cabinet still will not hold temperature, because what is left is the sealed system. Call the same day if nothing at all is cold, so that the food question gets decided quickly.
