What this means on this family
When the ARF line will not cool, the fault is usually in the path the cold air takes rather than in the machine that makes it. The table on this page covers a broad group of model numbers across several stems. Work the path from the door inwards and the expensive cause is the one you reach last, not first.
What an owner actually sees
- 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.
- The cabinet recovers overnight and drifts warm during the day — A machine that is only just coping. It points at heat rejection or at how often the door is opened rather than at a failed part.
- NEAR MISS — water pooling under the crisper with normal temperatures — That is a blocked defrost drain, covered on the water-leak page for this family, not a cooling failure.
Ranked causes for these models
- Blocked airflow from a frosted evaporator — Ranked first because on cabinets of this build the evaporator sits directly in the air path, so ice there stops cooling the cabinet before it stops the machine. Nothing else on this list produces a warm cabinet with a unit that is plainly working.
- A stopped or obstructed evaporator fan — Second. A fan that has stopped gives you the same warm cabinet with none of the frost to explain it, which is exactly why it sits behind the airflow check and not in front of it.
- A door that is not sealing on all four sides — Third, and worth checking before any panel comes off because it costs nothing. A cabinet that is fighting a leaking seal ices up faster, so the two top causes here are frequently the same fault at different stages.
- Dust or clearance at the condenser — Fourth, and it is the cause that produces the seasonal version of this complaint: fine all winter, warm in summer. Clearance and dust are owner-checkable without opening anything.
- Sealed system or compressor — Last. It is the expensive answer and the least likely one, so it should be reached by elimination and never assumed from the symptom alone.
What to check first, and why that order
- Check the setting and what the cabinet actually holds — A thermometer left inside for a few hours separates a control fault from a cooling fault, and it costs nothing.
- Walk the door seal by eye and by hand — Look along the closed door for daylight and feel for cold spilling out at the bottom corners.
- Listen at the freezer section for the internal fan — Placed after the free checks because it is the first step that needs a panel or a door switch held.
- Only then consider the compressor side — By this point three cheaper causes are eliminated, which is the whole reason for the order.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Sharp edges and a fan blade sit immediately behind most covers on cabinets of this build, so work with the power isolated rather than with the door switch propped. Refrigerant work is licensed work and is out of scope for an owner. 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
Call when the cabinet has been checked from the outside and is still warm, or the moment the fault is on the sealed system. A technician will want to know three things you can collect for nothing: whether the compressor runs steadily, whether air moves at the vent, and whether there is ice at the back of the freezer section.
