Error code9d/12
ApplianceRange
When a Kenmore 665 model freestanding range shows 9d/12, its control has judged the oven door lock assembly defective. Three other codes share that wording in the manual: 9d/11, 9d/21 and 9d/22.
Recommended order of checks
Begin with safety: disconnect the power or unplug the range. Then inspect the harness feeding the door lock assembly and push back on any wire that is not fully seated. A damaged harness is replaced rather than repaired. The last item is the lock assembly itself, which the manual replaces when damage can be seen.
When you need a Kenmore range technician in San Francisco
For a 9d/12 code that stays, phone (415) 825-6393 and a technician visit can be arranged anywhere in San Francisco or the surrounding Bay Area. Read out the code, the model number of the range and whatever you did with the harness. See also Kenmore range repair.
Model compatibility: Kenmore reuses codes across series and model years, so 9d/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.

What this code means

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
