What you are most likely looking at
A Commercial Cool refrigerator whose door will not seal is usually telling you one of three things: the gasket has gone hard and stopped gripping, the cabinet is no longer sitting level so the door does not swing shut, or a shelf or drawer is standing proud and holding the door off its face. All three are visible from the outside, and all three are owner territory. Where a cause needs test gear to confirm, the page says so rather than pretending otherwise.
What the owner sees
- 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. Mention it when you book a visit; it changes which parts a technician brings.
- 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. If the answer is clear, stop here and act on it.
- The door catches on the frame as it closes — Alignment rather than rubber: the door is arriving at the face at an angle.
- A cabinet that has been moved recently — Levelling changes when an appliance is moved, and a door that sealed in its old position may not in the new one. Note the result even if it is negative, because a ruled-out cause is progress.
Where the odds sit
- A hardened or creased door gasket — It is first on the list because age alone causes it. Nothing below this line is worth chasing until this one is ruled out.
- A twisted or racked door skin — Last because it is rare: a door that has been leaned on, or hung with weight on its handle, can twist enough that no gasket will seal it, and that is a door replacement rather than an adjustment. Ask whoever else uses the machine whether they have noticed the same thing.
- A seal that has lost its magnetic grip — The magnetic strip inside the gasket weakens with age, so the door meets the frame without ever being pulled tight.
- Flooring that has settled under the cabinet — The appliance has not changed; what it stands on has, and the door alignment follows the floor.
The diagnostic order
- Look along the gasket in a low light — A torch held inside the closed compartment shows a bright line at the leak. Note the result even if it is negative, because a ruled-out cause is progress.
- Check that the door falls shut from half open — A correctly levelled cabinet closes its own door from a little way open. The rank is a starting point, not a verdict; what you observe outranks it.
- Run a hand along the closed door for a cold draught — Escaping cold is easier to feel than entering warmth, and it finds the same leak. If you can only do one check, make it this one.
What an owner can safely check
- 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. Take a photograph before you disturb anything you will have to reassemble.
About 10 min
- Push a displaced gasket back into its channel — Work from the middle of the run outwards so the rubber is not stretched at the corner. Do this before the check below it, because the answer changes what that one means.
About 20 min
- Adjust the front feet so the cabinet leans slightly back — Test by opening the door half way and letting go; it should close under its own weight. It is worth doing properly once rather than quickly twice.
Tools: spanner, spirit levelAbout 25 min
- This is where the owner checks end — What is left is diagnosis rather than inspection, and diagnosis needs instruments.

Safety
The first step of every procedure here is the same: power off, at the plug or the consumer unit. Control boards can stay live briefly after the lights go out. Do not chip at ice with anything metal, because a holed liner ends the life of the cabinet. The machine is designed to stop when it is open, and it is meant to stay that way.
When this becomes a service call
Put the boundary here: cleaning, levelling, reloading the door and the paper test are yours; a gasket replacement or a hinge realignment is a judgement call. Everything on the owner side of it can be done in an afternoon. Call without waiting if you can smell burning, see oil around the compressor, or hear the unit trying to start over and over.
