The short answer
This page picks up where the first-pass checks end: with the gasket clean, reshaped and the cabinet level, a seal that still fails is a mechanical alignment problem, and the place where the paper test fails tells the technician which one. If you have not yet cleared the vents, tested the door seal and cleaned the condenser, start with the general page for this symptom, because everything below assumes those are done.
What you are seeing
- The paper test fails at one corner only
- The gasket feels hard, flattened or has a permanent crease
- Condensation or frost forming around the door frame
- The door alarm sounding although the door appears shut
- The compressor running almost continuously
- A near-miss symptom: condensation on the outside of the cabinet in a humid room, which is a room problem
- Body: These signs all point at the door: The paper test fails at one corner only. The gasket feels hard, flattened or has a permanent crease. Condensation or frost forming around the door frame. The door alarm sounding although the door appears shut. The compressor running almost continuously. A near-miss symptom: condensation on the outside of the cabinet in a humid room, which is a room problem.
Causes, most likely first
- The paper test fails at one corner only — Why: a single failing corner is a twist in the door or a dropped hinge, whereas a whole failing edge is a gasket that has taken a set; the distinction decides which part is ordered.
- A door that has dropped on its hinges — Why: the door must be lifted to close and the gap grows along the top, which is wear in the hinge rather than in the rubber.
- A gasket that has taken a set — Why: the rubber has a memory; after years the corners flatten and the door no longer pulls the seal onto the cabinet face.
- A misaligned door after reversal — Why: these doors are often re-hung to suit a kitchen, and a hinge left slightly out leaves a gap that shows in one corner only.
- A cabinet that is not level — Why: an out-of-square cabinet twists the door, and the seal then fails along one diagonal however good the rubber is.
- A dropped hinge — Why: the least common, showing as a door that must be lifted to close and a gap that grows over months.
- Body: Ranked for a cabinet with a push-fit gasket: First, The paper test fails at one corner only: a single failing corner is a twist in the door or a dropped hinge, whereas a whole failing edge is a gasket that has taken a set; the distinction decides which part is ordered. Second, A door that has dropped on its hinges: the door must be lifted to close and the gap grows along the top, which is wear in the hinge rather than in the rubber. Third, A gasket that has taken a set: the rubber has a memory; after years the corners flatten and the door no longer pulls the seal onto the cabinet face. Fourth, A misaligned door after reversal: these doors are often re-hung to suit a kitchen, and a hinge left slightly out leaves a gap that shows in one corner only. Fifth, A cabinet that is not level: an out-of-square cabinet twists the door, and the seal then fails along one diagonal however good the rubber is. Sixth, A dropped hinge: the least common, showing as a door that must be lifted to close and a gap that grows over months.
What to check, in order
- map exactly where the paper test fails all the way round and write it down, because that map is the diagnosis.
- close the door on a paper strip at the top, the sides and the bottom and note where it pulls out freely.
- wash the gasket and the cabinet face, because residue mimics a failed seal exactly.
- check the cabinet is level and sitting square, since a twisted cabinet defeats any gasket.
- Body: Test the seal before judging the rubber: First, map exactly where the paper test fails all the way round and write it down, because that map is the diagnosis. Second, close the door on a paper strip at the top, the sides and the bottom and note where it pulls out freely. Third, wash the gasket and the cabinet face, because residue mimics a failed seal exactly. Fourth, check the cabinet is level and sitting square, since a twisted cabinet defeats any gasket.
Checks you can do yourself
- Test the seal at eight points round the door and write down every place the paper pulls out freely — Tools: a paper strip and a pencil — Time estimate: a few minutes
- Wash the gasket and its channel with warm soapy water and dry it thoroughly — Tools: cloth, dish soap — Time estimate: a few minutes
- Close the door on a paper strip at several points and note every place it slides out freely — Tools: paper strip — Time estimate: a few minutes
- Warm a flattened section of gasket gently with a warm damp cloth and work it back into shape — Tools: warm damp cloth — Time estimate: a few minutes
- Check the cabinet is level and adjust the feet until the door swings shut under its own weight — Tools: adjustable spanner — Time estimate: a few minutes
- Body: The gasket is owner-serviceable; the hinges are borderline: Test the seal at eight points round the door and write down every place the paper pulls out freely (a paper strip and a pencil; a few minutes). Wash the gasket and its channel with warm soapy water and dry it thoroughly (cloth, dish soap; a few minutes). Close the door on a paper strip at several points and note every place it slides out freely (paper strip; a few minutes). Warm a flattened section of gasket gently with a warm damp cloth and work it back into shape (warm damp cloth; a few minutes). Check the cabinet is level and adjust the feet until the door swings shut under its own weight (adjustable spanner; a few minutes).
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. Do not use a heat gun or a hairdryer on a gasket or on ice: the liner is plastic and the tubing behind it carries a flammable refrigerant. A warm damp cloth is the only heat a gasket should see. unplug-before-service fridge-40f
When to stop and call a technician
These need a technician: The paper test fails at one corner only, which points at door twist rather than at the gasket. The gasket is split, torn or has come out of its channel. The door has to be lifted to close, which is a hinge fault. Frost keeps returning although the seal now passes the paper test.

What this page does not cover
This page is generalized across every refrigerator sold under the Blomberg name: it separates neither the counter-depth cabinets from the deeper ones and the freestanding models from the integrated 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. This page assumes the first-pass checks are already done; the general page for this symptom covers those, and the Bloomberg spelling covers the same cabinets in an integrated installation. For the other faults that turn up on this machine, start from Common Blomberg Refrigerator Problems.
