The short answer
A BRFT cabinet that is warm but audibly running is giving you the most useful clue there is: something is made cold and it is not reaching the food. That changes both the ranking and the first check compared with the brand-generic page.
What you observe
- 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.
- 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.
- 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 BRFT
- Condenser coil choked or its fan stalled — Ranked first on the BRFT family: heat has to leave the cabinet somewhere, and a coil matted with dust or a stalled compartment fan means the machine runs without ever winning. 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. This moves above blocked airflow from a frosted evaporator, which leads the brand-generic order, because these models share one layout, so its weak point shows across the whole family.
- 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.
- Blocked airflow from a frosted evaporator — Third: ice on the evaporator is not a side effect but the blockage itself: once the fins are bridged, the cabinet is sealed off from the only cold surface it has.
- Sealed-system or compressor fault — Fourth: last, and the one that decides the fate of the appliance rather than the repair; refrigerant work is licensed work and the diagnosis is not an owner diagnosis.
- Door seals, door alignment and loading — Last: the cheapest cause to rule out and a real one on a cabinet that runs continuously.
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.
