Direct answer: A dryer door that pops open is usually caused by lint packed around the latch area, a bent dryer door strike, a worn dryer door catch, or a door that has dropped slightly on its hinges.
Most likely: Start with the latch opening and door strike. On most dryers, that is where the problem shows up first and where the fix is simplest.
First separate whether the door never latches, latches but springs back open right away, or only pops open while the drum is running. That pattern tells you whether you are dealing with debris, latch wear, hinge sag, or a cabinet alignment issue. Reality check: this is usually a small mechanical problem, not a major dryer failure.
Don’t start with: Do not slam the door harder or tape it shut. That usually bends the strike, cracks the catch, or leaves you with a door that will not stay aligned at all.
The door meets the opening but never gives a solid latch click, or it feels like something is blocking it.
Start here: Check the latch slot and door strike for packed lint, a cracked plastic catch, or a strike that is bent off center.
You push the door closed, hear a weak click, and the door pops back out unless you hold it.
Start here: Look for a worn dryer door catch or a strike that is rounded off and no longer grabbing.
The door seems fine until the dryer is tumbling, then it pops open partway through the cycle.
Start here: Check for hinge sag, loose hinge screws, or a door that sits lower on the latch side when loaded vibration starts.
One corner sits proud, the gap is uneven, or the door scrapes before it closes.
Start here: Inspect the dryer door hinges and the front opening for looseness, warping, or a strike that no longer lines up with the catch.
This is the most common cause when the door suddenly stops latching or feels blocked. A little wad of lint in the catch opening is enough to keep the strike from seating.
Quick check: Open the door and look directly into the latch slot with a flashlight. If you see fuzz, hardened residue, or a broken plastic chip, clear it out and try the door again.
If the door gives a weak click or pops back open, the catch may be too worn to hold the strike under normal vibration.
Quick check: Press on the catch area with the door open. If the plastic is cracked, loose, or the latch action feels mushy, the catch is a strong suspect.
The strike takes the hit every time the door closes. If it is bent, loose, or rounded off, it may enter the catch but not lock in.
Quick check: Look at the strike on the door edge. If it is visibly off center, loose, or worn smooth where it should have a defined shape, it may not hold.
When the door drops even a little, the strike misses the catch or only grabs the edge of it. This often shows up as rubbing, uneven gaps, or a door that opens during tumbling.
Quick check: Lift gently on the open door. If you feel play at the hinge side or see the latch side rise noticeably, the hinges or hinge mounting are loose or worn.
Packed lint and small broken plastic pieces are common, easy to miss, and can keep a good latch from closing.
Next move: If the door now closes with a solid click and stays shut through a cycle, the problem was debris in the latch path. If the door still will not latch or still pops open, move on to the strike and catch inspection.
What to conclude: A blocked latch path can act exactly like a broken latch. Clearing it first keeps you from replacing parts you did not need.
A damaged strike is one of the most common reasons a dryer door clicks weakly or bounces back open.
Next move: If tightening or realigning the strike gives you a firm latch and the door stays shut, you likely solved it without further repair. If the strike looks worn or damaged, or it enters the opening correctly but still will not hold, the catch is the next likely failure.
What to conclude: A strike that is out of shape or no longer lines up cannot lock into the catch with enough bite to survive normal drum vibration.
If the strike reaches the opening but the door still springs back open, the catch itself is often worn out or cracked.
Next move: If replacing or securing the catch restores a firm latch, the door should stay shut normally again. If the catch looks sound but the door still sits low or rubs, the hinge side needs attention next.
A door that has dropped even slightly can miss the catch or only grab enough to hold until the drum starts moving.
Next move: If tightening the hinges restores alignment and the door now latches cleanly, run a short cycle to confirm it stays shut under vibration. If the hinges are tight but the door is still crooked, the hinge parts may be worn or the door frame may be distorted enough to need a closer repair inspection.
You want to confirm the door stays shut under normal vibration before ordering parts or putting the dryer back into regular use.
A good result: If the door stays shut through the test load, the repair path is confirmed and the dryer is ready for normal use.
If not: If the door still opens and no clear latch or hinge fault stands out, stop using the dryer until the door assembly can be inspected more closely.
What to conclude: A door that opens during operation is not just annoying. It can interrupt drying, stress the door parts, and in some cases let lint and heat escape where they should not.

Most often the latch is only barely catching. A worn dryer door catch, bent strike, or sagging door can hold while the dryer is still, then let go once vibration starts.
Yes. A small wad of packed lint in the latch opening can block the strike from seating fully. It is a simple check and worth doing before buying parts.
Replace the part that is visibly damaged or worn. If the strike is bent or rounded off, start there. If the strike looks fine but the latch feels weak or cracked, the catch is the better bet.
That usually points to hinge sag or loose hinge mounting. Lifting the door temporarily lines the strike back up with the catch, which is why it seems to work that way.
No. A door that opens during operation can interrupt drying, leak heat and lint, and put extra stress on the door assembly. Fix the latch or alignment problem before regular use.
