The short answer
When the BRFD family stops cooling while the compressor still runs, the fault is usually that cold air is not moving rather than that cold is not being made. This page ranks the causes for that build; the brand-generic article ranks them for the brand as a whole.
What you observe
- 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.
- Cabinet warm while the unit is clearly running — Cold is being made somewhere and is not arriving, which is an airflow question.
- 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 BRFD
- Evaporator or circulation fan not running — Ranked first on the BRFD family: 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. That is a family-level property rather than a model-level one, which is why it leads here. This moves above blocked airflow from a frosted evaporator, which leads the brand-generic order, because the family spans several sizes on one platform and it is the shared parts that wear.
- Blocked airflow from a frosted evaporator — Second: 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.
- Door seals, door alignment and loading — Third: 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.
- Condenser coil choked or its fan stalled — Fourth: 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.
- Sealed-system or compressor fault — Last: 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.
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.
- 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
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.
