Error code 9d/21
Appliance Range
Quick answer

9d/21 points to a defective oven door lock assembly on the Kenmore 665 model range.

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.

Plain language

What this code means

Oven door lock assembly defective.

Understanding 9d/21

This pair shows up on the Kenmore 665 model freestanding range when the oven door lock assembly is defective. The manual puts it in a set with 9d/11, 9d/12 and 9d/22.

What to do first

Disconnect power or unplug the range before touching anything. The lock assembly’s wire harness is next: any wires that are loose are reconnected, and a damaged harness is replaced. If the lock assembly shows visible damage, it is replaced.

  • 9d/12: listed with it
  • 9d/31: lock assembly error in Clean mode
  • 4d/52: door and lock switches disagree
