Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency

Quick answer
Your Samsung oven shows C-d1 because it detects a door lock malfunction. Turn the oven off and restart it; if it continues, turn the power off for at least 30 seconds and reconnect. If the code does not clear, contact a Samsung service centre.

- Do not force the door if it is locked and the oven is hot: let it cool. Do not take the door or the lock apart; that is a job for Samsung service.
Safe checks you can perform

Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Turn the oven off and back on
- Who:
- you.
- How:
- turn the oven off and then restart it, as Samsung instructs.
- Result that matters:
- whether C-d1 clears after the restart.
- If it clears and the oven works:
- it was a one off; watch for repeats.
- If it stays:
- move on to cutting the power for at least 30 seconds.
- Evidence to keep:
- a photo of the code on the display.

Cut the power for 30 seconds
- Who:
- you.
- How:
- turn off the oven power for 30 seconds or more (circuit breaker, or the plug if accessible) and reconnect it, as Samsung instructs.
- Result that matters:
- whether the oven starts without C-d1.
- If it does not return:
- it is solved for now; note the date.
- If it returns:
- Samsung refers you to its service centre; do not keep repeating the reset.
- Evidence to keep:
- a note of date and time of each occurrence and the model from the rating plate.

Check your model's manual
- Who:
- you.
- How:
- find the manual for your exact model (number on the rating plate), because Samsung warns that design and codes can vary by model.
- Result that matters:
- confirming C-d1 means the same on your oven.
- If the manual confirms it:
- follow its steps and, if it persists, contact Samsung.
- If the manual gives another meaning:
- follow your model's manual, not this page.
- Evidence to keep:
- a screenshot of the manual page with the code.

What it means
In Samsung's oven information code table, C-d1 is a door lock malfunction. Samsung notes that most of these codes are not a malfunction and clear with a reset, and that the design and codes can differ by model, so check it against your model's manual. The code alone does not prove the lock mechanism is broken: try the resets Samsung lists first.
