The short answer
When a Black+Decker refrigerator does this, a local frost patch is the entry point for humid air, which makes it the most precise leak indicator on the machine. Reading it is free. What it leads to is usually a clean, a reseat or a gasket.
What you actually see
- 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.
- The seal is hard, cracked or torn — The rubber loses its flexibility with age and stops recovering its shape after the door opens.
- A paper strip pulls out freely anywhere around the door — The paper test finds a leak faster than any other check on this list.
Causes, ranked for this refrigerator
- Gasket lifted out of its retaining channel — Leads the ranking — it looks attached from a step away, which is why it survives a casual inspection and keeps leaking. Where this checks out clean, treat the next entry as the working theory rather than a possibility.
- Gasket compressed flat from age — Close behind — the seal works by springing back into shape, and once the rubber has taken a set it cannot bridge the gap it used to. A clean result here does not just remove one part; it removes everything that depends on it.
- Dirt or sticky residue on the sealing face — A step down — it is easy to rule out and easy to fix, so it belongs high even though it is not glamorous. It is worth being sure about this one rather than half-sure, since everything after it assumes a verdict.
What to check, in order
- First — the gasket seating — Run a thumb around the inside edge of the gasket and feel for a section standing proud of the channel.
- Second — the gasket profile — Do the paper test every hand-width around the frame. Free-sliding paper marks the flattened section.
Checks an owner can do safely
- Step 1. 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.
Tools: noneAbout 10 min
- Step 2. Look for a wedge-shaped gap from the side — Sight along the closed door from one side. A gap that widens toward the top of the handle side is a hanging door rather than a flat seal.
Tools: noneAbout 5 min
- Step 3. Check the cabinet leans slightly back — Open the door a hand-width and let it go. It should close itself. If not, wind the front feet down until it does.
Tools: adjustable spanner or handAbout 15 min

Safety
Power comes off first, every time: pull the plug, or switch the breaker for that outlet. A capacitor can hold a charge after the power is off. Keep the cord where you can see it so nobody plugs it back in while your hands are inside, and never operate the unit with its cover removed.
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.

What this page does not cover
Read this as generalized information. It is accurate across the Black+Decker refrigerator range, which is exactly why it stops short of the detail a single family or model deserves. If a family-level or model-level page exists for your unit, that page supersedes this one on wiring, part numbers and error-code meanings; the links under Related pages are where those pages live.
