What this code means
The dryer believes the door is open when a cycle is requested or while the drum is running.
Most likely causes
- The door is not fully latched or clothing is caught in the opening
- The strike or hinge is misaligned
- The door switch is worn or damaged
- A wire or connector in the door-sense circuit is open
Safe checks for the owner
- Open the door, clear the opening and close it firmly.
- Inspect the strike and latch for visible breakage.
- Unplug the dryer briefly and retry after confirming the door closes squarely.
Estimated U.S. repair cost
$170–$330, depending on model, access, parts availability and local labor.
