Error codeC-d1 / Cd1
ApplianceMicrowave
Spotted Cd1 on a Samsung microwave? Samsung’s table reads it as a door or key error. Samsung gives C-d0 and C-d2 the very same description. It belongs to the code set for today’s Samsung microwave line.
Resetting the microwave after C-d1
Switch the supply off at the breaker, or simply disconnect the power cord.
Where liquid or cooktop steam reached the microwave, give it time to dry out.
No moisture at all: hold off for 60 seconds, then plug in or flip the breaker back on.
If the display shows Cd1 once more, ask for service.
Back-to-back C-d1 after a restart? San Francisco and Bay Area owners can contact us on (415) 969-6153, and Samsung microwave repair explains the service. Gather the model number, the code and a note on your reset first.
Model compatibility: Samsung reuses codes across series and model years, so C-d1 / Cd1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
