Error code9d/21

Why 9d/21 appears
On the Kenmore 665 model freestanding range, 9d/21 is the message for a defective oven door lock assembly. Four manual entries share that meaning: 9d/11, 9d/12, 9d/21 and 9d/22.
Step sequence
Cut the electricity, either at the supply or by pulling the plug.
Look at the wire harness of the lock assembly and push loose wires back where they belong.
A harness that is damaged gets a new one.
When the lock assembly itself shows damage you can see, it is exchanged as well.
Codes that look alike
9d/22: shares this defective lock assembly meaning
Owners in San Francisco and the wider Bay Area can book a technician for a 9d/21 range by calling (415) 825-6393. Before dialing, find the model number on the range and jot down which harness checks you have already made. More on the work is under Kenmore range repair.
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.
