The short answer
A Beko BUFR freezer that runs without holding temperature is usually losing airflow or gaining heat through a failing seal rather than losing refrigerant. A freezer holds food safely at 0 °F (-18 °C) or below, and on these cabinets the gap between that and a soft load is normally explained by ice, a gasket or a blocked vent.
What you observe
- Ice cream is soft while packaged goods still feel firm — On the models listed in the table on this page, the earliest useful sign, because soft ice cream indicates a few degrees of loss long before anything thaws.
- Frost building heavily on the walls or the load — Warm humid air entering repeatedly deposits moisture that freezes, so heavy frost is evidence of a seal or door problem rather than of cold.
- The compressor runs continuously and never cycles off — A cabinet that never reaches its target keeps running, so continuous operation is a symptom rather than a cause. The models in the table behave the same way here.
- NEAR MISS: the cabinet is silent and nothing is cold — That is a no-power or start fault rather than a cooling one, and the logic on this page does not apply to it.
Causes, most likely first
- A door gasket that no longer seals — First on the BUFR line because it admits a continuous stream of warm humid air, which both raises the temperature directly and lays down the frost that goes on to block the airflow. That holds across every model this page covers.
- Heavy frost build restricting circulation — Second because it follows from the first and because it is self-reinforcing: ice reduces airflow, reduced airflow means longer run times, and longer run times deposit more ice. That is true of every model this family spans.
- Overpacking against the vents or the rear wall — Boxes pressed against the cold wall or over a circulation vent stop air moving, which leaves pockets of the cabinet several degrees warmer than the setpoint.
- A dirty or obstructed condenser — Dust and pet hair stop the system rejecting heat, so the compressor runs longer for less effect. Common in households with animals and easy to check.
- A sealed-system or compressor fault — Last on this platform because it is the least common cause and the only one that is not an owner check. Refrigerant work is licensed work and the tools for it are not owner tools.
Check in this order, and why
- Test the seal with a sheet of paper all round the door — First on the BUFR line because it costs nothing and because a section that pulls out with no resistance names the most common cause outright. It is the same on all the models in the table on this page.
- Look for heavy frost on the walls or behind the baskets — Second: a thick build confirms repeated humid air entry and tells you roughly how long it has been going on.
- Pull packed items away from the rear wall and any vent — For every model in this family, free, instant and the whole fault often enough to be worth doing before anything is dismantled.
Before you begin
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A freezer holds food safely at 0 °F (-18 °C) or below, so move anything that matters to a cooler with ice before starting work.

When to call a technician
Call when the seal, the frost, the packing, the condenser and the door closure are all proven and the cabinet still will not hold temperature. On the BUFR line that leaves the sealed system or the defrost control. The same is true of each model covered here.
