When a dryer door won’t close the machine stops being a dryer entirely — it will not start, will not tumble and usually will not even acknowledge the start button, because the door interlock is a safety system rather than a convenience. The good news is that this is one of very few appliance faults you can diagnose by looking straight at the part that failed. Two small components do the work: a strike on one side of the opening and a spring-loaded catch on the other.
Before either of them, two free causes are worth ruling out, because both manufacturers name them first and neither involves the latch at all.
The dryer is not broken; it is declining to run
A dryer whose door never confirmed shut is not a failed appliance. It is a working appliance refusing to heat a drum it cannot see the inside of, and nothing downstream of that switch — motor, heater, timer, display — is implicated. This is why a door problem presents as a completely dead machine and sends people hunting for electrical faults. If the panel lights but Start does nothing, the door is near the top of a very short list. A cycle that begins and then quits is a different fault: dryer keeps shutting off covers a door popping open mid-cycle, and a machine with no sign of life belongs on dryer won’t turn on.
Overload it and a dryer door won’t close at all
Whirlpool puts this ahead of every part, and the mechanism is straightforward: a packed drum pushes outward on a door designed only to hold itself shut. “Overloading the dryer could cause the dryer door not to latch” (Whirlpool — Door Not Closing, Dryer). LG says the same and attaches a number, which beats an adjective: “Excessive or bulky laundry may cause the door to open… Be sure to fill only half of the drum” (LG — why is a dE error code displayed?). Clothes expand as they dry rather than contract, so a drum that closed at the start of a cycle can genuinely stop closing by the middle of one.
Whirlpool’s second free check is obstruction, and it names the thing nobody expects to still be there: “Ensure all packing and/or shipping material has been removed, and no clothing is blocking the latch.” On a newly delivered machine, look in the opening before you look at parts. LG adds the nearly invisible one — a lint filter not pushed fully home sits proud of its housing and holds the door off its catch by a couple of millimetres, which is plenty.
The strike and the catch, and which one actually broke
Every ranking page for this search belongs to a parts retailer, which is worth saying out loud: RepairClinic, Home Depot’s repair-parts site and Sears PartsDirect occupy almost the whole first page, and all of them are selling the component. That does not make the description wrong, and Sears PartsDirect’s is the clearest available — “when the door is closed, the spring-loaded door catch encloses and grips the door strike, which is mounted across from it” (Sears PartsDirect).
Its test for telling the two apart is the one genuinely useful sentence in that whole SERP: “If the door won’t latch closed and the strike is intact, replace the catch.” Look at the strike first, because it is the part you can judge by eye — bent, chewed or missing has visibly failed. If it looks untouched and the door still will not hold, the catch spring has lost its grip. There is a third outcome, and it is the expensive one: a warped door shell or bent hinge means neither small part will help, because the strike no longer lines up with the catch. LG flags it on new machines — “look for damage such as a bent door.”
Whirlpool says to check the feet. It is not a typo
This is the check that sounds unrelated and is not, and no competing page mentions it. Whirlpool’s door article asks “Is the dryer level?” and answers with a direct causal claim: “All four dryer feet should be in firm contact with the floor. If not level… clothes may not tumble properly, causing the door to not properly close.” The mechanism is a cabinet that is not square to itself — a dryer resting on three feet carries its weight diagonally, and the front panel, where the catch is mounted, twists slightly out of alignment with the door. Push each corner in turn. If it rocks, that is free to fix and worth doing before ordering a part that was never faulty.
What a scorched door switch looks like
The switch is not what holds the door shut; it is what tells the control the door is shut, and a failed one produces the identical dead-machine symptom. GE makes it an observation rather than a test: “Open the dryer door and inspect the condition of the door switch. If the door switch is scorched or pushed in, this may cause the dryer not to operate” (GE Appliances — Dryer Will Not Run or Start). Scorched or pushed in — both visible with the door open and a torch, neither needing a meter. One more thing: some dryers carry an upper and a lower latch, and both must engage before the machine runs, which explains a door that feels shut and behaves as though it is open.
Never wedge, tape, jam or bypass a door switch to make the dryer run. That interlock is why a heated, turning drum stops when the door opens, and defeating it is not a repair at any price.
Observations that decide between a catch and a new door
- The strike tab is visibly bent, chewed or missing. Replace the strike.
- The strike is intact and the door still will not hold. The catch spring has gone.
- You can see daylight along one edge of a closed door. The shell or hinge is distorted; small parts will not fix it.
- It holds with the drum half empty and pops open when full. Nothing is broken. Load less.
- The door switch is scorched or stuck pushed in. GE’s own stop condition.
FAQ
Why won’t my dryer start if the door is shut?
Because the control never saw it shut. The door switch has to make contact first, so a worn switch, a latch not fully engaged, or a second latch on a two-latch door all read as an open door.
What is the difference between a dryer door strike and a door catch?
The strike is the small protruding tab, usually on the door. The catch is the spring-loaded part across from it that encloses and grips the strike. The strike is judged by eye; the catch by whether it still holds.
Can an overloaded dryer stop the door closing?
Yes, and both Whirlpool and LG name it before any part. Clothes expand as they dry, so a drum that closed at the start can push the door open later. LG’s figure is to fill only half the drum.
My dryer door won’t close on a brand-new machine. Is it faulty?
Check the opening for packing and shipping material, then the lint filter seating. LG also describes new door gaskets settling in over the first two or three uses, and says to look for a bent door.
Is it safe to tape the dryer door shut?
No. The interlock stops a heated, rotating drum the moment the door opens, and bypassing it removes that. If the door will not hold, the latch parts are inexpensive and the repair is small.
Look at the catch, not the price list
Three things before a single part is ordered: take half the load out, push the lint filter fully home, and press each front corner to see whether the cabinet rocks. Then open the door and look at the strike. Bent means the strike; intact means the catch. That is the whole diagnosis, and it takes two minutes with a torch.
The one genuinely bad answer is a warped door or a bent hinge, because the fix is a whole door assembly rather than a few pounds of hardware. On a dryer past eight years old, that is the point to price a replacement machine before the repair.
