Straight to it
A Craftsman refrigerator whose door no longer seals loses cold air every minute of the day. The paper test settles it in a minute and costs nothing, and it is the only way to turn an impression into something a technician can act on. Read the near-miss line in the symptoms first if you are not sure you are on the right page.
Signs, including the misleading ones
- NEAR MISS: the door seals but the cabinet still will not hold temperature — With a sound gasket, a warm cabinet points at airflow or the sealed system, which is a different page entirely.
- The cabinet runs far longer than it used to — A leaking door is a continuous heat load, which shows in run time before it shows in temperature. Note the result even if it is negative, because a ruled-out cause is progress.
- Marks or shine on the seal where it rubs the frame — The door is meeting the face at an angle rather than flat, which is alignment rather than rubber. It is worth confirming twice before you act on it, since one observation can mislead.
- A draught you can hear rather than feel — Air moving past a gap is audible in a quiet kitchen, and it comes from the point that is leaking. Repeat it once if the answer is ambiguous rather than moving on with a maybe.
The ranking
- The cabinet is out of level or the feet have dropped — It ranks high because floors are rarely flat.
- A sagging hinge or a loose hinge plate — Less common than the gasket but real, especially on a heavy door: as the top hinge wears, the door drops at the handle side and the gasket line stops matching the cabinet. Check whether anything changed in the house around the time it started.
- Mould and staining stiffening the folds — The growth itself is harmless to the seal, but the cleaning it needs is often the fix as well.
- A frame packed too tightly into a surround — A built-in cabinet squeezed at the sides can distort just enough to change the contact line of the seal.
Where to start, and why there
- Run a sheet of paper around the whole seal line — Close the door on it and pull: where it slides out with no resistance, the gasket is not touching. Do this before the check below it, because the answer changes what that one means.
- Empty the door bins and try again — Loading is free to rule out and it explains a surprising share of door complaints, so do it before you go anywhere near a hinge. A cause in this position is worth eliminating before you spend anything.
- Empty the door bins and try again — It separates a weight problem from a seal problem in one move and costs nothing. If the answer is clear, stop here and act on it.
The homeowner checks
- Redistribute the door load and push every drawer home — Move bottles from the door racks to a shelf, make sure no drawer or shelf stands proud of the liner, and close the door slowly to feel where it stops early. This is safe owner work as long as the power is genuinely off.
About 10 min
- Check the defrost drain channel for standing water or ice — Clear the visible channel with warm water from a jug and a soft cloth. It needs nothing you do not already own.

- Tighten the visible hinge fasteners — With the hinge cover off, snug the screws that hold the plate to the cabinet. Have a towel to hand before you start.

- Stop here if the next step would put a meter on live terminals — What is left is diagnosis rather than inspection, and diagnosis needs instruments.
Before you open anything
Safety
Power off first. Everything else on this page assumes you have done it. Treat the wiring as live until you have proved otherwise, whatever the switch says. Refrigerant work is licensed work: a line opened without the right recovery gear vents the charge and turns a repair into a replacement. Nothing here asks you to interfere with a switch that senses the door, and nothing should.
When to stop and call
One rule decides it: a gasket you can clean, warm, flatten or reseat is yours, and a door that is twisted, a hinge that is worn through, or a cabinet flange that has been bent is not. Past that point, a wrong guess is expensive rather than merely annoying. Call without waiting if you can smell burning, see oil around the compressor, or hear the unit trying to start over and over.
