The short answer
On the BRUF family a cabinet that runs without cooling is far more often an airflow or defrost problem than a dead compressor. That puts the evaporator and its fan above the sealed system in the order, which is the opposite end of the brand-generic list.
What you observe
- Cabinet warm while the unit is clearly running — Cold is being made somewhere and is not arriving, which is an airflow question.
- A sheet of frost on the evaporator or the rear wall — A stalled defrost: the ice itself is now blocking the air path.
- Freezer side still cold, fresh-food side warm — Near-diagnostic on a shared-evaporator cabinet, and it points at the air path rather than the system.
- The unit never cycles off — A machine that cannot reach its target runs continuously and works its compressor far harder than normal.
- NEAR MISS - silent and not cold — That is a no-power or start-relay fault and belongs on a different page.
Causes, most likely first on BRUF
- Blocked airflow from a frosted evaporator — Ranked first on the BRUF family: this family runs a small evaporator behind a rear panel, so a defrost that stalls ices the whole air path within days rather than weeks. Every model code in the table above shares the same air path, which is why this ranks above the sealed system rather than below it. What moves against the brand-generic order is lower down: condenser coil choked or its fan stalled sits above door seals, door alignment and loading here, because these models share one layout, so its weak point shows across the whole family.
- Evaporator or circulation fan not running — Second: the fan is the one part in the cold side that turns continuously, and a cabinet that warms from the top down is usually telling you it has stopped.
- Condenser coil choked or its fan stalled — Third: the condenser is tucked into the machine compartment on this family and blocks with dust and pet hair quickly.
- Door seals, door alignment and loading — Fourth: the free check, and a genuine finding on any cabinet that has started running without stopping: a seal that no longer meets loads the machine continuously.
- Sealed-system or compressor fault — Last: last, and the only cause here that is not owner-checkable: refrigerant work is licensed work.
Check in this order, and why
- Listen at the cabinet for the circulation fan — It separates the two likeliest causes before any panel comes off.
- Check nothing is packed against the rear vents — Blocked vents give exactly the same symptom as a failed fan and cost nothing to rule out.
- Pull the unit out and check the condenser and its fan — Worth doing early because it needs no tools and no panel removed.
- Test each door seal with a sheet of paper — Last, because it explains a struggling cabinet rather than a warm one.
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. Shut the water supply at the stop tap before touching any fill line, and treat the sealed system as off limits: refrigerant work is licensed work.
When to call a technician
Call once the fan runs, the coil is clean and the seals are good but the cabinet is still warm: what is left is the defrost circuit or the sealed system, and neither is owner work on this family.
