The short answer
The Arieta ARBF refrigerator family covers a single listing in the roster below, and on that platform the first split is whether both compartments are warm or only one. A cabinet that has gone warm while the machine is plainly running is telling you that cold is being made and not delivered, which is a different fault from cold not being made at all. The order below is built so the checks that need no tools come before the ones that need the machine moved or a panel off.
What you observe
- Both compartments are warm and the machine is running continuously — Either the air path is blocked at the source or the system is no longer moving heat.
- Water pooling under the crisper drawers as well as a warm cabinet — Melt from a stalled defrost has to go somewhere. Water inside the cabinet alongside the warmth points firmly at the defrost path rather than at anything else on the list.
- One shelf or one drawer is warm while the rest is fine — Air distribution rather than cooling capacity. A blocked vent, a drawer not seated or food packed against an outlet will all starve one part of the cabinet.
- The cabinet recovers overnight and warms again during the day — Door openings are the load. A machine that only just copes will hold temperature when the kitchen is quiet and lose ground when it is not, which points at capacity rather than a failed part.
- NEAR MISS — the machine is silent and nothing is cold at all — No compressor sound, no fan, no light behaviour: that is a power, relay or control fault rather than the cooling path, and it is a different page from this one.
Causes, most likely first on the ARBF line
- Airflow blocked by frost on the evaporator — Ranked first here, because defrost systems stall long before they fail outright, so ice builds quietly over weeks while the cabinet gives up a degree at a time, and by the time an owner notices the warmth the frost sheet is already the whole story. Nothing in the roster below splits these listings apart for this fault, so the order that follows holds across the whole label.
- Condenser coil blanketed with dust, or the condenser fan stopped — Second here, because the machine can only move heat as fast as it can dump it, so a coil under a felt of dust turns a healthy system into one that runs constantly and still loses ground on a warm day.
- Thermostat or temperature sensor reading wrongly — Third here, because a control can only act on what it is told, so a sensor reading colder than the compartment really is will satisfy the machine early and leave the food warm.
- Defrost heater, sensor or control no longer completing the cycle — Last here, because it sits behind the frost it causes: the frost is the symptom you can see, and which of the three parts failed is the part of the diagnosis that needs a meter and the panel off.
Check in this order, and why
- Compare the two compartments before anything else — A hard-frozen freezer with a warm fresh-food side is an air-path fault. Both warm is a source fault.
- Put a thermometer in each compartment and wait — A dial is a setting rather than a reading. A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below, and a measured figure tells you how far off you are.
- Pull the machine out and look at the condenser — Dust on the coil and a condenser fan that is not turning are both visible from the back or through the lower grille, and both are owner-serviceable with the machine unplugged.
Safety first
Safety
Take the plug out before the first screw, not after it: a capacitor can hold a charge after the power is off, and the fan behind a cover starts the moment power returns. Do not run a machine that is tripping its breaker, and do not keep restarting a compressor that clicks and falls silent — both states put heat into a part that cannot use it. Keep perishables at 40 °F (4 °C) or below while the cabinet is down, and remember that refrigerant work is licensed work at every stage..
Models in the ARBF family — Every listing above is covered by this article rather than by a page of its own; a page written for a single model would go further than this one does. The numbers are reproduced from platform data rather than transcribed.

Where the owner side ends
Call immediately if the condenser tubing stays at room temperature while the compressor is plainly running, or if there is oil anywhere on the tubing: that is a sealed-system diagnosis and it is not an owner repair at any stage. A machine that runs continuously without reaching temperature works its compressor far harder than normal, so a cheap fault left alone for a month can become an expensive one.
