Error code 4d/12
Appliance Range
Quick answer

Kenmore 665 freestanding ranges show 4d/12 when the door and door lock switches disagree.

Model compatibility

Kenmore reuses codes across series and model years, so 4d/12 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Oven door and oven door lock switches disagree.
