The short answer
When a BLZSSRFDBDR unit runs continuously and the food is still warm, treat it as a heat-rejection fault first. The condenser on these cabinets sits where the owner cannot see it and the clearance around it is tight, so the same dust layer that a full-size refrigerator shrugs off stops this platform cooling altogether.
What you observe
- Sweating or condensation around the door opening — Warm room air is reaching the cold surface, which means the seal is not closing along its whole length.
- A sheet of frost on the inside rear wall — A light dusting is normal. A solid sheet means the air path is closed and cold is no longer moving into the cabinet.
- The unit never stops running — A cabinet that cannot reach its setting runs without a break.
- It runs for a short spell, stops, and starts again quickly — Short cycling is a different pattern from continuous running and points at the start components or at overheating rather than at airflow.
Causes, most likely first
- A condenser coil or grille blanketed in dust — Ranked first on this family. The condenser is small, it is close to the floor or the wall, and the clearance around it is measured in fingers.
- Too little clearance, or a warm location — Placement is a genuine cause on this platform, not an excuse. Pushed tight to a wall, boxed into a cabinet run, or standing in a warm utility space, these units have nowhere to put the heat they remove.
- A door seal that no longer grips along its whole length — Second, and the cause owners most often miss. A compact cabinet loses its whole reserve to a small leak, and the seal on a light door takes a set if the unit has been transported or stored shut.
- A failed evaporator or condenser fan — On models that use a fan rather than free convection, a fan that has stopped gives exactly the warm cabinet of a blocked coil, with no dust to show for it. Listen for it before opening anything.
Check in this order
- Put a separate thermometer in the cabinet and read it after some hours — It separates a cabinet that is genuinely warm from one whose control display is wrong, and it costs nothing.
- Listen at the back for the compressor and any fan — Running and warm is a different fault from silent and warm, and this one check splits the list in two before any tool comes out.
- Close the door on a strip of paper and pull it out, at several points around the opening — On a compact cabinet the seal is the cheapest real cause, and this is the fastest honest test of it.
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. Do not attempt anything on the sealed system: the refrigerant circuit on this family is brazed closed, it carries no service ports an owner can use, and opening it is licensed work.

When to call
Call once the door, the clearance and the condenser are all clean and the cabinet still will not hold temperature. That is the point at which the remaining causes are inside the machine.
