The short answer
The door on a Costway compact dryer carries both the seal that keeps warm air in the drum and the switch that lets the machine run. Most door complaints are lint in the seal, a catch that is not seating, or a door that has been knocked out of true from the machine being moved.

Causes, ranked for this machine
- Lint packed into the door seal or the catch — Why this rank: First because it is free to fix and it prevents both a clean close and a good seal
- A catch or strike that is not seating, so the door pops open under tumbling — Why this rank: The load pushes on the door constantly, and a marginal catch gives way partway through
- A door knocked out of true by the machine being moved or carried — Why this rank: Portable machines are moved for storage, which no fixed dryer experiences
- An overfilled drum pressing the load against the door — Why this rank: Free to correct and a common cause of a door that opens mid-cycle
- A perished seal or a worn hinge — Why this rank: Last because it needs a part and everything above it is free
- Body: Ranked for a compact or portable dryer on a household outlet: either a vented machine with a short flexible hose, or a ventless machine that collects condensate in a tank or sends it down a drain hose. Most likely: Lint packed into the door seal or the catch. First because it is free to fix and it prevents both a clean close and a good seal. Next most likely: A catch or strike that is not seating, so the door pops open under tumbling. The load pushes on the door constantly, and a marginal catch gives way partway through. Third: A door knocked out of true by the machine being moved or carried. Portable machines are moved for storage, which no fixed dryer experiences. Fourth: An overfilled drum pressing the load against the door. Free to correct and a common cause of a door that opens mid-cycle. Fifth: A perished seal or a worn hinge. Last because it needs a part and everything above it is free.
What to check, in order
- Clear lint from the seal and the catch with the machine unplugged
- Close the door firmly and check the machine responds
- Reduce the load and see whether the door still pops open
- Look along the closed door for a gap or a twist
- Body: Each check rules out the causes above it. First, clear lint from the seal and the catch with the machine unplugged. Second, close the door firmly and check the machine responds. Third, reduce the load and see whether the door still pops open. Fourth, look along the closed door for a gap or a twist.
Checks you can safely make yourself
- Unplug the machine and wipe lint out of the door seal and the catch recess, working right into the fold — Tools: cloth, brush — Time estimate: a quarter of an hour
- Close the door firmly and check the machine responds, then nudge it and confirm the machine stops — Tools: none — Time estimate: a few minutes
- Run a cycle with half the usual load and note whether the door still opens partway through — Tools: none — Time estimate: one cycle
- Close the door and sight along its whole edge for a gap or a twist against the cabinet — Tools: none — Time estimate: a few minutes
- Look at the catch and the strike for bending, wear or a missing fixing — Tools: torch — Time estimate: a few minutes
- Body: Checks an owner can make with the machine unplugged or by watching a short cycle. Step one: Unplug the machine and wipe lint out of the door seal and the catch recess, working right into the fold. Tools: cloth, brush. Time: a quarter of an hour. Step two: Close the door firmly and check the machine responds, then nudge it and confirm the machine stops. Tools: none. Time: a few minutes. Step three: Run a cycle with half the usual load and note whether the door still opens partway through. Tools: none. Time: one cycle. Step four: Close the door and sight along its whole edge for a gap or a twist against the cabinet. Tools: none. Time: a few minutes. Step five: Look at the catch and the strike for bending, wear or a missing fixing. Tools: torch. Time: a few minutes.
Safety first
Safety
Unplug the machine before working on the door or the seal, and never tape or bypass a door switch to keep a heated dryer running. Warm air escaping at the door is a sign of a poor seal rather than a hazard, but a door that opens under load is worth correcting before the next cycle. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. unplug-before-service
Where the owner fix ends
Call for a warranty claim or a technician when the seal and catch are clear of lint, the load is reduced, the door sits square and it still pops open or still will not latch. A catch, a hinge or a seal is a parts job inside the door.
