Quick answer

Code 9d/21: the oven door lock assembly on a Kenmore 665 model range is defective.

Model compatibility

Kenmore reuses codes across series and model years, so 9d/21 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
