Error codeC-d1
ApplianceRange
The lock on your Samsung range door is not working correctly when C-d1 shows. Samsung lists this information code simply as a door lock malfunction.
Owner steps
Shut the oven off and start it up again.
If the code is still on the display, remove power for at least 30 seconds.
Connect the power back and see whether C-d1 has cleared.

The word door is a different thing, since it says the door is not closed. C-d0 is a pressed-and-held button, and C-F0 refers to components that cannot communicate with one another.
