Kenmore Range 3d/12 Error Code

Reading 3d/12

The display pair 3d/12 tells the owner that the oven temperature sensor is defective. Owners of the 665 model freestanding Kenmore range will see codes in this slash format; the manual groups 3d/12 with three siblings that have the same meaning.

Steps in the manual’s order

Power comes off first, by disconnecting or unplugging the range. Next the sensor’s wire harness gets attention, since loose wires are pushed back on and a harness that is damaged is replaced. Measuring the sensor’s resistance is a job for a technician with a volt/ohm meter, and a sensor that fails the manual’s check is replaced. When both sensor and connections pass, the electronic oven control is replaced.

Compare with these codes

• 3d/11: shares this sensor meaning
• 3d/22: listed under the same manual entry
• 1d/12: oven too hot in Bake or Broil mode
• 4d/11: oven door and door lock switches disagree
