The answer first
A Criterion dryer whose door will not stay shut is usually a worn catch or a moved strike rather than a broken hinge. The machine stops the instant the latch loses contact, so the symptom reads as a cycle fault while the cause sits in your hand. Where a cause needs test gear to confirm, the page says so rather than pretending otherwise.
What the owner sees
- Hot air escapes around the door edge — The seal has hardened or worn, so heated air leaves without passing through the load. Time it roughly, as the pattern matters more than the exact interval.
- The door is loose on its hinge — Hinge fasteners work loose over years of use, and a dropped door stops meeting its catch. The value is in eliminating, not confirming; most of these come back negative and that is useful.
- Drying has become slower without any other change — Air bypassing the load through a poor seal produces exactly this, and nobody connects it with the door. Mention it when you book a visit; it changes which parts a technician brings.
- NEAR MISS: the machine will not start at all with the door shut — That is the door switch rather than the catch, and it belongs on the will-not-start page. It takes less time than reading about it.
Where the odds sit
- A worn door catch or latch tongue — Ranked first because it operates every cycle and wears into a shape that no longer holds against drum vibration. Treat the ordering as a route through the possibilities rather than as a prediction.
- A strike plate that has moved or bent — Second because it is cheap, adjustable and frequently the whole fault once the fasteners have loosened. Check whether anything changed in the house around the time it started.
- A hardened or torn door seal — Heat cycles stiffen the seal until it stops making contact, which costs drying performance before it costs anything else. Treat the ordering as a route through the possibilities rather than as a prediction.
- Loose or worn hinge fasteners — A door that has dropped even slightly no longer presents its catch squarely, so it holds sometimes and not others. Mention it when you book a visit; it changes which parts a technician brings.
The order that saves time
- Look at the catch and strike for wear marks — Bright or rounded metal where they meet is the wear that lets a door pop open. Do it with the machine in its normal state rather than after you have already changed something.
- Run a hand round the door edge while the machine runs — Escaping warm air locates a seal leak in a few seconds without any tool. Nothing below this line is worth chasing until this one is ruled out.
- Check the seal for tears, flattening and lint — A seal that has been snagged by clothing tears progressively, and the damage is always visible. If you can only do one check, make it this one.
Steps you can do yourself
- Tighten the hinge and strike fasteners — Snug rather than force them, then close the door and check that the catch meets the strike squarely. Leave the machine a few minutes afterwards before you decide it has not helped.
Tools: screwdriverAbout 20 min
- Adjust the strike plate position if it is slotted — Move it a fraction towards the catch, tighten, and test the door several times before running a cycle. If the answer is clear, stop here and act on it.
Tools: screwdriverAbout 20 min
- Wash the seal and check it for tears — Warm soapy water and a cloth. Have a towel to hand before you start.
Tools: cloth, detergentAbout 15 min
- The last owner step is the one above this line — Everything beyond here belongs to somebody with a meter and the habit of using it properly.
The safety floor
Safety
Pull the plug before anything else; a wall switch is not proof the appliance is dead. Control boards can stay live briefly after the lights go out. Lint is fuel; take it out of the machine rather than pushing it further along the duct. The machine is designed to stop when it is open, and it is meant to stay that way.
When to stop and call
One rule decides it: cleaning, tightening and adjusting are yours; replacing a catch assembly, a door switch or a bonded seal is not. A technician draws the same line, for the same reasons. Do not keep cycling a machine that bangs, drags or smells hot in the hope it settles.
