The short answer
On cabinets of this vintage the gasket ranks first rather than last, because a magnetic seal that has spent decades compressed against a frame takes a permanent set and stops springing back. Everything else on this page follows from age too: hinge bushings that have worn, and a furniture housing that has settled since the appliance was fitted into it.
What you are seeing
- The gasket feels hard and does not spring back when pressed — Note: It has taken a permanent set. This is the age-driven first cause on cabinets of this generation.
- A paper strip pulls out freely along one whole vertical edge — Note: Hinge geometry, most often a door reversed at some point and never re-shimmed square.
- A paper strip pulls out at the top corner on the handle side only — Note: The hinge bushing has worn and the door has dropped, which is a wear pattern rather than a seal one.
- On a built-in cabinet, the furniture door drags or does not follow the appliance door — Note: The sliding coupling between the two has slipped on its rail.
- Frost returns as a blanket within days of a full defrost — Note: Humid room air is entering continuously, and the seal is the supply line for that frost.
- The seal passes a paper test everywhere and the cabinet is still warm — Note: The door is not your problem. The cooling page ranks the causes for a warm cabinet.
Ranked causes on this brand
- Gasket hardened and taken a permanent set — Why this rank: First on this badge because the installed base is old. A magnetic strip that has been compressed for decades stops returning to shape, and a gasket that will not spring back cannot seal however well the door is hung.
- Hinge bushings worn, letting the door drop — Why this rank: Second because it is the other age-driven failure: the bushing wears gradually, the door settles, and the leak appears at the top corner on the handle side specifically.
- Sliding coupling slipped on a built-in furniture door — Why this rank: Third because it applies only to built-in installations, but where it applies it is decisive: the furniture panel and the appliance door are joined by a coupling on a rail, and a slipped one drags the door out of square.
- Door reversed at some point and never re-shimmed — Why this rank: Fourth because reversible hinges are standard on this platform and cabinets of this age have often been moved between kitchens, sometimes more than once.
- Cabinet held out of square by a settled furniture housing — Why this rank: Fifth because the appliance is only as square as the carcass it is shimmed into, and carcasses settle on old floors.
- Inner door panel separated from its foam — Why this rank: Last because it is uncommon and terminal: once the door bows in the middle, no hinge adjustment brings the centre of the gasket to the frame.
What to check, in order
- Press the gasket with a thumb and watch whether it springs back — Why: A strip that stays flattened has taken a set, which is the top-ranked cause on cabinets of this age and cannot be adjusted out.
- Close each door on a strip of paper at four points on each of the four sides — Why: The pattern of where it pulls free separates hardening, hinge geometry and a worn bushing.
- Lift the open door gently at the handle end and feel for play — Why: Movement at the top corner points at a worn hinge bushing rather than at the seal.
- On a built-in cabinet, open the appliance door and watch whether the furniture door follows it exactly — Why: A furniture door that lags or drags means the sliding coupling has slipped on its rail.
- Put a spirit level on the cabinet and check the fixings holding it to the carcass — Why: A settled housing twists the appliance and no door adjustment will correct that.
Checks you can do safely
- Press the gasket firmly with a thumb at several points along each run and note anywhere it stays flattened rather than springing back. — Tools: none — Time: ten minutes
- Close each door on a strip of paper at four points on each side and write down every point where the strip slides out freely. — Tools: a strip of paper — Time: a quarter of an hour
- Warm any rolled or flattened section with a hair dryer on its lowest setting, held well back, press it into shape and let it cool with the door closed. — Tools: hair dryer — Time: twenty minutes
- If the cabinet is built into furniture, slacken the fixings to the carcass, let it settle square on its own feet, and retighten. — Tools: screwdriver — Time: twenty minutes
- Loosen both hinges, close the door onto its seal so it self-centres, and retighten from the closed position rather than the open one. — Tools: screwdriver or nut driver, a helper — Time: half an hour
- On a built-in cabinet, slacken the sliding coupling between the furniture panel and the appliance door, close both, and retighten with them aligned. — Tools: screwdriver — Time: half an hour
Before you open anything
Safety
Unplug the refrigerator before removing a hinge, a panel or any trim, and support the door or have a helper hold it before the last hinge screw comes out. Keep a hair dryer moving, on its lowest heat and well back from the plastic liner, which deforms permanently at surprisingly low temperature. Never tape or wedge the door switch closed to stop the lamp, because a lamp burning inside a sealed cabinet is a heat source. A refrigerator is top-heavy, so get help before moving it and do not tilt it far. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. — Id: unplug-before-service A refrigerator holds food safely at 40 °F (4 °C) or below. — Id: fridge-40f
Where the service line falls
The gasket has hardened and no longer returns to shape after warming, which needs a replacement matched to the channel profile. A hinge bushing is worn enough that the door drops visibly, which cannot be corrected by adjustment. The paper test passes everywhere and the cabinet still will not hold 40 °F (4 °C) or below. The inner door panel has separated from its foam so the door bows, at which point the door rather than the seal is finished. A gasket is needed. Take the rating plate photograph, because on this badge a seal is matched by channel profile and door dimensions against the group-sibling machines rather than ordered by brand name.

What this page does not cover
This page covers both production generations and describes the reversible-hinge, magnetic push-in gasket arrangement common to the platform, including built-in cabinets with a furniture door on a sliding coupling. It describes no one model family. For the everyday symptom-first version of this diagnosis, use the brand page rather than this manufacturer-entity one. This page is addressed to the manufacturer entity rather than to a single cabinet, so it covers both production generations and describes no one model family. Everything here depends on the rating plate inside the liner, which names the platform and is what a parts desk cross-references against the group-sibling badges that shared it.
