The short answer
Read the machine before you read the manual — on a Black+Decker refrigerator, a door that will not close itself is usually a levelling problem before it is a seal problem. Winding the front feet down is free and takes minutes; a hinge that has worn is where it stops being owner work.
What you actually see
- Frost forming near one edge of the freezer section — A local frost patch marks the exact point where humid air is entering.
- The compressor runs far more than it used to — A leaking door is a continuous load, and longer run times are the first measurable effect.
- 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
- Cabinet out of level so the door will not swing shut — Top of the list: it outranks the gasket on a unit that was recently moved, because moving is what changes it. Confirm it before moving on, because the entries below read differently once it is ruled out.
- Something inside holding the door open — Next: an overfull door shelf or a container standing proud of a shelf will hold the door a fraction open with no visible gap. Rule it in or out properly here; a maybe at this position costs an hour further down.
- Hinge worn or loose so the door hangs low — Then: 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. Getting a definite answer here is worth more than a quick look at the three below it.
What to check, in order
- First — the levelling feet — Open the door a hand-width and let go. It should swing closed. If it hangs or opens further, the cabinet leans forward.
- Second — what is on the door shelves — Empty the door shelves and the top shelf, then repeat the paper test.
Checks an owner can do safely
- Step 1. 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
- Step 2. 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.

- Step 3. Warm a set gasket and reshape it — A gasket that has taken a set can sometimes be revived with a warm damp cloth held against it for a few minutes, then worked back into shape by hand.

Safety
Nothing on this page is done with the appliance live. Unplug it or switch its breaker off, remember that a capacitor can hold a charge after the power is off, and leave every factory-fitted switch and cut-out exactly as you found it.
When this becomes a service call
The line is not about confidence, it is about what the next step needs. If the seal passes the paper test all the way round and the cabinet still runs constantly, the fault is not the door and the cooling checks are the right page.

Generalized by design.
