The short answer
Here is what the symptom means on a Black+Decker refrigerator: a machine that never stops is fighting a load that never stops, and an open door seal is the most common such load. The seal checks are free and fast; if the seal passes all the way round, this is a cooling question instead.
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.
- The seal is hard, cracked or torn — The rubber loses its flexibility with age and stops recovering its shape after the door opens.
- 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 — Ranks first because the seal works by springing back into shape, and once the rubber has taken a set it cannot bridge the gap it used to. This is the entry most often blamed correctly and diagnosed carelessly, so take the extra minute.
- Dirt or sticky residue on the sealing face — Second because it is easy to rule out and easy to fix, so it belongs high even though it is not glamorous. Confirm it before moving on, because the entries below read differently once it is ruled out.
- Cabinet out of level so the door will not swing shut — Third because a light compact cabinet is easy to set slightly forward-leaning, and a door that will not close itself gets left ajar dozens of times a week. Rule it in or out properly here; a maybe at this position costs an hour further down.
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 sealing surface — Wipe the gasket and the frame it meets with warm soapy water and dry both. Note whether anything comes off.
Checks an owner can do safely
- Step 1. 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 2. Run the paper test around the whole door — Close the door on a sheet of paper and pull. Repeat every hand-width. Free-sliding paper marks a leak; drag means the seal is holding there.
Tools: sheet of paperAbout 10 min
- Step 3. 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.

Before you open anything
Safety
Take the power away before the panel. Unplug the appliance or open its breaker; a capacitor can hold a charge after the power is off, so a dead-looking board is not a safe board. Work with dry hands on a dry floor and put the panel back before power goes on.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. Call when the gasket is split or has taken a permanent set — a new gasket has to match the door, and on some cabinets the inner panel comes off to fit it.

What this page does not cover
One limitation worth stating up front: this page is written for the Black+Decker refrigerator range rather than for your particular unit. It does not name families, model numbers or control revisions. Where a page exists that does, it is more precise than this one and it is linked under Related pages.
