Quick answer

Kenmore 665 model range code 4d/52: the oven door switch and lock switch disagree.

Kenmore reuses codes across series and model years, so 4d/52 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
