The short answer
A freestanding counter-depth Blomberg refrigerator gives up cabinet depth to sit flush with the worktop, and that shallow cabinet is the first thing to understand about a cooling complaint: there is less room behind the shelves, so food reaches the rear vents far more easily than in a deep American cabinet. Clear the vents before anything else. A refrigerator holds food safely at 40 °F (4 °C) or below.
What you are seeing
- Food at the back of a shelf is freezing while the front of the same shelf is warm
- The fridge section is warm while the freezer below stays hard
- Everything in both sections is warm and the compressor runs constantly
- Milk on the top shelf is fine and salad in the drawer is warm
- Items at the back are freezing while the door shelves are warm
- The compressor never starts and the cabinet is completely silent
- Body: What is warm, and where, is most of the diagnosis: Food at the back of a shelf is freezing while the front of the same shelf is warm. The fridge section is warm while the freezer below stays hard. Everything in both sections is warm and the compressor runs constantly. Milk on the top shelf is fine and salad in the drawer is warm. Items at the back are freezing while the door shelves are warm. The compressor never starts and the cabinet is completely silent.
Causes, most likely first
- A shallow counter-depth cabinet packed to the rear wall — Why: there is much less clearance behind a shelf than in a full-depth cabinet, so ordinary loading blocks the vents that a deeper fridge would tolerate. This is the cause that is specific to this cabinet shape.
- Insufficient clearance at the top and sides of the recess — Why: a freestanding cabinet slotted into a tight gap between units cannot reject heat sideways or upwards, and it runs continuously without reaching its setting.
- Blocked air vents at the back of the fridge section — Why: a tall bottle or a tray pressed to the rear wall stops cold air reaching the shelves below, and it is the reason one shelf is warm while another is not.
- A door that is not sealing — Why: a gasket held open by a package or a shelf pushed proud lets warm moist air in continuously, and the cabinet cannot win against it.
- Frost blocking the evaporator — Why: when the defrost system falls behind, the ice sheet behind the rear panel blocks the fan, and the freezer stays cold while the fridge warms.
- A dusty condenser or a blocked ventilation gap — Why: the cabinet has to reject heat somewhere; a felted coil or a cabinet pushed hard against a wall traps it and the compressor runs without effect.
- Body: Ranked for a fan-circulated cabinet with the evaporator behind the rear wall: First, A shallow counter-depth cabinet packed to the rear wall: there is much less clearance behind a shelf than in a full-depth cabinet, so ordinary loading blocks the vents that a deeper fridge would tolerate. This is the cause that is specific to this cabinet shape. Second, Insufficient clearance at the top and sides of the recess: a freestanding cabinet slotted into a tight gap between units cannot reject heat sideways or upwards, and it runs continuously without reaching its setting. Third, Blocked air vents at the back of the fridge section: a tall bottle or a tray pressed to the rear wall stops cold air reaching the shelves below, and it is the reason one shelf is warm while another is not. Fourth, A door that is not sealing: a gasket held open by a package or a shelf pushed proud lets warm moist air in continuously, and the cabinet cannot win against it. Fifth, Frost blocking the evaporator: when the defrost system falls behind, the ice sheet behind the rear panel blocks the fan, and the freezer stays cold while the fridge warms. Sixth, A dusty condenser or a blocked ventilation gap: the cabinet has to reject heat somewhere; a felted coil or a cabinet pushed hard against a wall traps it and the compressor runs without effect.
What to check, in order
- measure the gap around the cabinet against the clearance in the installation instructions, because a freestanding cabinet in a tight recess behaves exactly like one with a failed fan.
- clear the vents at the back of the fridge section and leave a gap between food and the rear wall.
- test the door seal with a paper strip at several points, since air ingress defeats every other correction.
- read the control panel for a mode or a setting that has been changed.
- Body: Work from the free checks to the expensive ones: First, measure the gap around the cabinet against the clearance in the installation instructions, because a freestanding cabinet in a tight recess behaves exactly like one with a failed fan. Second, clear the vents at the back of the fridge section and leave a gap between food and the rear wall. Third, test the door seal with a paper strip at several points, since air ingress defeats every other correction. Fourth, read the control panel for a mode or a setting that has been changed.
Checks you can do yourself
- Pull items forward off the rear wall of every shelf and leave a hand’s width clear at the back — Tools: none — Time estimate: a few minutes
- Move food away from the vents in the rear wall of the fridge section and leave a clear gap — Tools: none — Time estimate: a few minutes
- Close the door on a paper strip at the top, both sides and the bottom and note where it pulls out freely — Tools: paper strip — Time estimate: a few minutes
- Check the control panel for holiday, eco or fast-cool modes and return the setting to normal — Tools: the model manual — Time estimate: a few minutes
- Unplug the cabinet, pull it forward and vacuum the condenser coil and the ventilation gap — Tools: vacuum, soft brush — Time estimate: half an hour or so
- Body: None of this requires the cabinet to be emptied: Pull items forward off the rear wall of every shelf and leave a hand’s width clear at the back (none; a few minutes). Move food away from the vents in the rear wall of the fridge section and leave a clear gap (none; a few minutes). Close the door on a paper strip at the top, both sides and the bottom and note where it pulls out freely (paper strip; a few minutes). Check the control panel for holiday, eco or fast-cool modes and return the setting to normal (the model manual; a few minutes). Unplug the cabinet, pull it forward and vacuum the condenser coil and the ventilation gap (vacuum, soft brush; half an hour or so).
Safety first
Safety
A refrigerator holds food safely at 40 °F (4 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Compact refrigeration uses a flammable hydrocarbon refrigerant: never puncture the evaporator, never chip ice with a tool, and never use a heat gun or an open flame to clear frost. unplug-before-service fridge-40f
When to stop and call a technician
These are past the owner line: The cabinet cannot reach its setting despite clear vents and the clearance the installation instructions require. The compressor runs constantly and the cabinet still will not reach its setting. The freezer is cold and the fridge is warm after the vents and the seal have been cleared. The compressor never starts with power confirmed at the outlet.

What this page does not cover
This page is generalized across every refrigerator sold under the Blomberg name: it separates neither the counter-depth freestanding cabinets from the deeper ones and the bottom-freezer layouts from the single-door ones, and it names no individual model. Where a family- or model-specific page exists it is linked here and it outranks this one for that machine; at present no page beneath this one narrows to a single family, so treat the ranking above as the brand-level pattern rather than a reading of your serial plate. The same cabinets are also listed under the alternate capitalisation and under the common misspelling Bloomberg; those pages cover the built-in installation and the deeper diagnostic tier, and they are linked here. For the other faults that turn up on this machine, start from Common BLOMBERG Refrigerator Problems.
