The short answer
A Beko BRFB refrigerator that stops holding temperature is a built-in cabinet, and on a built-in the first suspect is never the machine: it is the ventilation path through the housing. The appliance breathes through grilles designed into the joinery, and if those are blocked or were never cut, the condenser cannot reject heat no matter how healthy it is.
What you observe
- The compressor runs almost continuously and the cabinet is still warm — Heat is being made and not rejected - the housing ventilation until proven otherwise.
- The plinth grille is warm and the air behind it is still — Condenser heat with nothing carrying it away.
- One compartment warm with the other cold — That compartment's door seal or its airflow.
- A sheet of frost on a rear wall inside — A stalled defrost cycle, with the ice now doing the blocking.
- NEAR MISS - silent and warming — Nothing is running, which is a supply or start-relay fault.
Causes, most likely first on this family
- Housing ventilation blocked or never provided — First on any built-in, and the cause most often missed because it is in the kitchen rather than in the appliance.
- Custom door panel holding the door fractionally open — Second, and specific to built-ins: a heavy or badly hung panel can stop the door pulling fully home.
- Door gasket not sealing along its full height — Third, and usually alignment rather than wear.
- Frost or a stopped fan blocking airflow — Fourth, and the reason one compartment warms while the other holds.
- Stalled defrost or sealed-system fault — Last, and the only pair needing instruments.
Check in this order, and why
- Check the plinth grille and the top of the housing for airflow — First, because on a built-in this is the leading cause and it is checked with a hand.
- Look into the void behind the plinth for stored items — Second. Anything pushed into that space blocks the only air path the appliance has.
- Close the door and watch whether the panel pulls it fully home — Third, and unique to a built-in with a custom panel.
- Read both compartment temperatures — Fourth, because one warm or both warm routes the rest of the diagnosis.
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. Never chip ice off an evaporator with a metal tool. Do not attempt to draw a built-in cabinet out of its housing alone - it is heavy, it is held by concealed fixings, and a custom panel makes it front-heavy.

When to call a technician
Call once the housing ventilates, the door pulls fully home and the gaskets seal. Call immediately if you see oil at the compressor or smell burning - oil outside the tubing means the system is open.
