The short answer
On the BDFW family a cabinet that will not hold temperature is far more often an airflow problem than a dead compressor. These are compact cabinets with a small condenser and very little clearance around it, so anything that blocks heat leaving the back shows up as warm food long before the sealed system is at fault.
What you observe
- 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.
- One compartment is cold and the other is not — On models with a separate freezer section, cold in one and warm in the other points at airflow between them rather than at the compressor.
- 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.
- The unit never stops running — A cabinet that cannot reach its setting runs without a break.
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.
- 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.
- 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.
- The thermostat or control sensor reading wrong — The sensor is a small part in a fixed position, and once it reads warmer than the cabinet really is the control simply never calls for more cooling. It gives a cabinet that is cold but not cold enough, rather than one that is plainly warm.
Check in this order
- 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.
- Feel the back of the cabinet for heat while it runs — A unit that is working but cannot shed heat feels hot at the back; one that is not pumping at all does not.
- Measure the gap behind and above the unit against the room it stands in — This comes early because it is free to fix and because a cabinet with no clearance will defeat every repair that follows.
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. These cabinets are light enough to move alone and heavy enough to tip - empty it first, and pull it out rather than walking it on its corners.

When to call
Call when the cabinet runs continuously with a clean coil and a good seal, or when it will not start at all. Both point past the owner-checkable list.
