The short answer
Reversible doors are standard on this platform, and a door that has been swapped to suit a kitchen and not re-shimmed square is the leading cause of a seal that leaks along one edge. The second is the housing itself: a cabinet built into a furniture run can be held out of square by the housing rather than by anything wrong with the appliance. A genuinely perished gasket comes a long way down the list.
What you are seeing
- A paper strip pulls out freely along one whole vertical edge — Note: One edge open and three tight is the signature of hinge geometry, usually a door reversed and not re-shimmed.
- The door has to be pushed the last part of its travel — Note: The cabinet is tilted forward, or the housing is holding it out of square.
- Condensation or frost forms around one corner of the door frame — Note: Room air is finding a path in at that point and giving up its moisture there.
- Frost returns as a blanket within days of a full defrost — Note: Humid air is entering continuously. The seal is the supply line for that frost.
- The gasket is rolled under itself along one run — Note: A soft magnetic strip that has twisted in its channel, which reshapes with gentle heat.
- 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
- Door reversed at installation and never re-shimmed square — Why this rank: First because reversible hinge kits are standard on this platform, the swap takes minutes and is done without a level, and the result is a door hanging proud on one side and leaking along that whole edge.
- Cabinet held out of square by its furniture housing — Why this rank: Second because these cabinets are commonly built into a run of units and shimmed to the carcass, so a housing that has settled or was never square twists the appliance itself.
- Magnetic gasket rolled or displaced in its channel — Why this rank: Third because the gasket is a push-in strip with a magnet inside and it distorts whenever something is forced past it, which is invisible from the front.
- Cabinet not level on its feet — Why this rank: Fourth: it stops the door falling shut on its own, so the door is habitually pushed rather than closed, and one day it is left resting against the frame.
- Hinge pin or bushing worn, letting the door drop — Why this rank: Fifth because it produces a leak at the top corner specifically, which distinguishes it from every cause above.
- Gasket perished, hardened or torn — Why this rank: Last because the geometry causes above it produce identical symptoms far more often, and fitting a new gasket to a badly hung door changes nothing.
What to check, in order
- 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 is the diagnosis: one edge, one corner, or everywhere.
- Look at which side the hinges are on and ask whether the door was ever swapped — Why: A reversed door is the top cause and this question finds it in seconds.
- Put a spirit level on the top of the cabinet, front to back and side to side — Why: A forward tilt means the door has to be pushed shut, which is how it ends up merely resting on the frame.
- Run a finger along the whole gasket looking for a rolled or folded section — Why: A roll cannot be seen from the front and is the commonest single-edge leak after hinge geometry.
- Open the door and lift gently at the handle end, feeling for play — Why: Movement at the top corner points at a worn hinge pin or bushing rather than at the seal.
Checks you can do safely
- Close each door on a strip of paper at four points on each side and write down every point where the strip slides out without resistance. — Tools: a strip of paper — Time: a quarter of an hour
- Put a spirit level on the top of the cabinet and adjust the feet until it sits dead level or a hair back, then check the door falls shut from half open. — Tools: spirit level, adjustable wrench — Time: twenty minutes
- If the cabinet is in a furniture housing, slacken the fixings holding it to the carcass, let it settle square, 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
- Warm any rolled section of gasket with a hair dryer on its lowest setting, held well back, press it flat into shape and let it cool with the door shut. — Tools: hair dryer — Time: twenty minutes
- Empty the door shelves of anything standing proud of the inner face and repeat the paper test. — Tools: none — Time: ten minutes
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: 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 paper test passes everywhere, the cabinet is level and square in its housing, and it still will not hold 40 °F (4 °C) or below. The gasket is torn, split or has hardened so that it no longer returns to shape after warming, which means a replacement matched to the channel profile. A hinge pin or bushing is worn enough that the door drops visibly, which cannot be corrected by adjustment. The inner door panel has separated from its foam so the door bows in the middle, at which point no hinge adjustment brings the gasket to the frame. The cabinet cannot be brought square in its housing, which is a kitchen fitting matter rather than an appliance one.

What this page does not cover
This page is generalized across families and models and describes the reversible-hinge, magnetic push-in gasket arrangement common to this platform. It does not describe any one model family, and it does not cover fully integrated cabinets with a furniture door on a sliding hinge rail, whose door faults are about the rail rather than the appliance hinge. For parts sourcing and for telling one production generation from another, work from the manufacturer-entity page rather than this one: the same platform was sold under several group badges, and a parts desk cross-references by platform rather than by the name on the door.
