What dn means

dn on a Samsung dryer with a digital display means a download is in progress. The dryer is loading new firmware, and it is not an error. During the download you should not unplug the dryer or shut it off. When the download finishes, the dryer restarts itself. If dn is still showing after 24 hours, the update has not completed and the dryer needs service.

Common causes of dn

A firmware download that is still running
An update interrupted by a power loss or a poor connection
A dryer that cannot complete the update on its own

✓ One safe check you can try

1. Leave the dryer plugged in and powered on. 2. Do not press Power, open the breaker, or unplug it. 3. Wait for the dryer to restart on its own. 4. If dn is still showing after 24 hours, stop and have it looked at.

! Why to stop there

A download that never finishes can leave the control stuck, which a restart will not fix.
We check the power to the dryer and whether the control can accept the update.
You get a written price before we begin, and our work has a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

dndn questions

Is dn an error on my Samsung dryer?

No. It means the dryer is downloading an update. It is a normal message, and the dryer returns to normal on its own when the download completes.

Can I use the dryer while dn is showing?

No. Wait until the dryer restarts. Interrupting a download can leave the control in a bad state, so do not unplug it or switch it off.

How long is too long for dn?

On a dryer, give it up to 24 hours. A washer message with the same letters waits a much shorter time, so do not compare them. After a full day, the dryer needs service.
