The short answer
Test the seal with a sheet of paper at several points. A door that fails the test, is sagging, or has a dirty or hardened gasket lets warm air in continuously - which shows as sweating, frost, longer running and a warmer cabinet.
What you notice
- Moisture on the cabinet face or door edge — Warm air condensing at a leak.
- The machine runs far more than it used to — A continuous heat leak.
- Frost building in the freezer compartment — The moisture that air brought in.
- The door does not pull itself closed — A tired gasket or a sagging door.
- Cabinet light staying on — The door is not closing fully.
- Not this fault: condensation on a drink taken out of the machine — That is the room, not the appliance.
Ranked for kitchen use
- Gasket hardened or torn — First, and it is a wear part.
- Gasket dirty, so it cannot seat — Second, and cleaning may fix it outright.
- Door sagging on its hinge — Third, common on a heavily loaded door.
- Shelves or containers fouling the opening — Fourth.
- Cabinet not level, so the door does not swing shut — Fifth.
- Hinge or closure hardware worn — Last.
Check it in this order
- Run the paper test around the whole door — It shows exactly where the seal fails.
- Clean the gasket and the cabinet face — Residue alone can hold a door open.
- Look along the door for sag against the cabinet — A dropped door leaks at the top corner.
- Check the cabinet is level and tilted slightly back — Doors are meant to swing shut.
Owner checks
- Test with paper at the top, the sides and the bottom of each door — Corners fail before straight runs.
Tools: paperAbout 15 min
- Wash the gasket and the sealing face with warm soapy water — Spills glue a gasket into a bad shape.
Tools: clothAbout 20 min
- Check nothing on the shelves stands proud of the opening — Bottles and boxes hold doors open every day.
About 10 min
- Level the cabinet and set a slight backward tilt — It lets the door close under its own weight.
Tools: spirit levelAbout 25 min
- Watch for the cabinet light going out as the door closes — A simple check that the door is truly shut.
About 5 min
- Stop before replacing a gasket or adjusting a hinge — Door alignment is part of that job.
Working on doors
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Keep the refrigerator at or below forty degrees Fahrenheit and the freezer at or below zero degrees Fahrenheit while you investigate. A loaded refrigerator door is heavy - support it before loosening any hinge fixing, and never leave a door removable where children can reach it.
When to call
Call when the gasket is clean and intact, nothing fouls the opening, the cabinet is level and the seal still leaks - that points at the hinge or the door itself. Call sooner if the compartments are warming, because a leak that big is costing food. Ask about gasket availability and price, which on a value-tier machine decides the repair.

Scope of this page
Generalized across refrigerator families under this badge in ordinary kitchen installations; where a family-specific or model-specific page exists it is the narrower answer. Not here: gasket part numbers, hinge specifications and door dimensions.
