The short answer
The short answer for a Black+Decker refrigerator: beads on the frame mark where warm room air is meeting cold cabinet air, and the wettest spot is the leak. Finding it is free; whether it ends in a clean, a reseat or a new gasket depends on what the paper test shows.
What you actually see
- The door does not pull itself shut over the last inch — A door left to swing should close under its own weight from a hand-width open on a level cabinet.
- A visible gap at one corner of the closed door — Gaps almost always start at the top hinge corner or the bottom of the handle side.
- Frost forming near one edge of the freezer section — A local frost patch marks the exact point where humid air is entering.
Causes, ranked for this refrigerator
- Gasket compressed flat from age — Most likely — the seal works by springing back into shape, and once the rubber has taken a set it cannot bridge the gap it used to. If this is the answer, the rest of the list stops mattering entirely.
- Hinge worn or loose so the door hangs low — Common — it shows as a gap that is worst at the top of the handle side, which is the signature of a door dropping on its hinges. Where this checks out clean, treat the next entry as the working theory rather than a possibility.
- Dirt or sticky residue on the sealing face — Regular — syrup, milk or grease on the gasket face stops it releasing cleanly, and the seal tears itself slightly on every opening. A clean result here does not just remove one part; it removes everything that depends on it.
What to check, in order
- First — the gasket profile — Do the paper test every hand-width around the frame. Free-sliding paper marks the flattened section.
- Second — the hinges — Lift the door handle gently. Movement at the hinge means play that the seal is being asked to take up.
Checks an owner can do safely
- Step 1. Clean the gasket and its sealing face — Warm soapy water on a cloth, into the folds, then dry both surfaces. Sticky residue stops a good gasket from sealing.
Tools: cloth, warm soapy waterAbout 15 min
- Step 2. Reseat any lifted section of gasket — Run a thumb around the inner edge and press any proud section back into its channel. A section that will not stay needs the retaining panel checked.
Tools: noneAbout 10 min
- Step 3. Check the door shelves for obstructions — Empty the door and the top shelf, close the door slowly and watch the last inch for contact before it is home.

Before you open anything
Safety
Before a single screw comes out, unplug the appliance or switch off its breaker. A capacitor can hold a charge after the power is off. Work dry, keep one hand out of the cabinet, and leave any interlock or cut-out switch exactly as the factory fitted it.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. The owner side ends at cleaning, reseating, levelling and reshaping. A hinge that has worn, or a door out of plane after a reversal, is a fitting job.
