Error code C-d0 / Cd0
Appliance Microwave
Quick answer

C-d0 (Cd0) is a door or key error on a Samsung microwave. Unplug, let it dry or wait, then request service if it returns.

Model compatibility: Samsung reuses codes across series and model years, so C-d0 / Cd0 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
