Samsung Dryer High Light Blinking: Door Problem

Medium · inspection needed

Code: High or 40 min light blinking

Brand: Samsung
Warranty: 30-day workmanship

What High or 40 min light blinking means

On Samsung dryers without a digital display, a blinking High or 40 min light is a door-related error. The dryer is reporting a problem with the door, the latch, or the sensors that detect them. The panel on these models has lights rather than a screen to show the message. The dryer stops or will not start while the light blinks, because the control does not accept that the door is closed.

Common causes of High or 40 min light blinking

A door that is not fully closed
Something caught in the door or seal
A latch or door switch not registering
A loose connection between the door switch and the control

✓ One safe check you can try

1. Open the door and make sure nothing is caught, such as clothing or a sleeve. 2. Look at the latch and catch for damage or lint. 3. Close the door firmly until it clicks. 4. Press Start again. 5. If the light blinks again with the door closed, stop using the dryer.

! Why to stop there

A door that looks closed may still not trip the switch, so we test the switch directly.
We check the latch, the switch wiring, and the control's reading of the door.
We provide a written price first, and we give 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.

High or 40 min light blinkingHigh or 40 min light blinking questions

Are High and 40 min the same message?

On indicator-light Samsung dryers, either light blinking is listed as the door-related error. Which one blinks depends on your model, and the checks are the same.

Why does the dryer say the door is open when it is closed?

The latch or door switch may not be registering. Lint, a worn catch, or a loose connection can cause that, and a test of the switch shows which.

Can I bypass the door switch?

No, and we would not. The switch stops the drum when the door opens, so it is a safety device. We repair it rather than work around it.
