What this usually is
An Arieta refrigerator that runs without cooling has usually lost airflow rather than refrigerant: the evaporator ices up, the fan can no longer push cold air into the fresh-food compartment, and the cabinet warms while the compressor works harder than ever. Confirm with a thermometer, deal with the food, then work the airflow checks before anybody talks about a sealed system.
What you actually see
- Fresh food warm, freezer still holding — The airflow signature: cold is still being made, and it is not arriving.
- Both compartments warming with the compressor running — Heat rejection or the sealed system. A different and more urgent branch.
- A frost sheet across the freezer rear wall — The blockage itself, visible.
- Condensation inside the fresh-food compartment — Humid air entering past a tired seal and condensing where the cold is.
- NEAR MISS: warm for a day after a large shop — A loaded warm cabinet takes many hours to recover and that is not a fault.
The ranking that matters
- Iced evaporator blocking airflow — First on this class of unit because adaptive defrost degrades quietly: the ice builds for weeks before the warmth is noticed.
- Evaporator fan not running — Second. The same warm-forward symptom without the frost sheet, which is how the two are told apart.
- Condenser coil under dust — Third, and the reason a unit that has never been cleaned struggles first in hot weather.
- Door seal leaking — Fourth, and it is often the upstream cause of the first.
- Sealed system loss — Last, least common, and the only one no owner check will resolve.
Work down this list
- Put a thermometer in the fresh-food compartment — A number now, and another in two hours, tells you whether anything is working.
- Compare the two compartments by hand — Warm-forward with a cold freezer means airflow.
- Listen at the freezer for the fan — It separates an iced coil from a dead fan in seconds.
- Look at the condenser and the space around the unit — Free, and it is a real cause in warm rooms.
The checks you can run yourself
- Move perishables to a cooler with ice — A refrigerator holds food safely at 40 degrees Fahrenheit or below, and this step is the reason the rest can wait.
Tools: cooler, iceAbout 20 min
- Read the thermometer after two hours with the door shut — It distinguishes a slow decline from a complete failure.
Tools: thermometerAbout 120 min
- Vacuum the condenser and clear the space behind the unit — Dust and a wall against the back both cost real cooling capacity.
Tools: vacuum, soft brushAbout 25 min
- Empty the cabinet and defrost fully with the doors open — Overnight. If cooling returns, the defrost system is the subject. Stop here rather than removing the evaporator cover.

What can hurt you here
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and the defrost heater sits immediately behind the panel most people reach for. Never chip ice off an evaporator: the tubing is directly behind it and a puncture ends the appliance and vents refrigerant into the room. Warm air and time are the only safe defrosting tools.
Where the owner fix ends
Call when cooling does not return after a full defrost, because that means the defrost system itself has failed rather than merely fallen behind. Call promptly when both compartments are warm with the compressor running continuously, since every hour in that state is wear you cannot recover. Sealed-system work is licensed work in most places, so refrigerant repairs are never an owner job whatever a video suggests.

Scope of this page
This page is the class-level answer for an Arieta refrigerator that will not cool. It gives no refrigerant charges, no defrost timings and no part numbers, because those differ between builds under this badge and sealed-system data is not owner information. Where a family- or model-specific page exists it carries the evaporator and defrost layout for that unit. Refrigerant handling is regulated work everywhere and stays outside this page.
