The short answer
On the BRFB 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 BRFB
- Blocked airflow from a frosted evaporator — Ranked first on the BRFB 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. What decides the order here is where the cold has to travel, and that is fixed for every model in the family. 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 the platform has run in many trims, and the parts common to every trim accumulate the failures.
- Evaporator or circulation fan not running — Second: the fan sits behind the rear panel on this platform and is the moving part that wears first.
- 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 cheapest cause to rule out and a real one on a cabinet that runs 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.
- Look behind the rear panel for a frost sheet — A solid sheet rather than a light dusting confirms a defrost fault.
- Compare the two compartments against each other — One cold and one warm is an air path; both warm is the system or the condenser.
- 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
Isolate at the breaker before any panel comes off, and leave the sealed system alone entirely: refrigerant work is licensed work and the tools for it are not owner tools.
When to call a technician
A refrigerator holds food safely at 40 °F (4 °C) or below and a freezer at 0 °F (−18 °C) or below; move perishables once the cabinet is above that. Cleaning a condenser and testing seals are owner work. Call as soon as the sealed system is suspected, because refrigerant work is licensed work.
