The short answer
A BRFB 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 BRFB
- Condenser coil choked or its fan stalled — Ranked first on the BRFB family: the condenser is tucked into the machine compartment on this family and blocks with dust and pet hair quickly. These codes share an evaporator arrangement and a defrost scheme, so a finding on one is worth assuming on the rest. 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: 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.
- Sealed-system or compressor fault — Fourth: last, and the only cause here that is not owner-checkable: refrigerant work is licensed work.
- 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.
- 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.
- 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. Refrigerant work is licensed work, so leave the whole sealed system to a licensed technician, and call at once if you see oil at the compressor or smell burning.
When to call a technician
Call immediately if you see oil at the compressor or smell burning, because oil outside the tubing means the system is open. Otherwise call when the owner checks above are clean and the temperature has not recovered overnight.
