Error code1d/12
ApplianceRange
If a Kenmore 665 model freestanding range reads 1d/12, the oven has run hotter than it should in Bake or Broil. The manual puts 1d/12 in one entry with 1d/11.
Sequence
Power off the range at the supply, or pull the plug.
Reconnect loose wires on the oven temperature sensor wire harness; a damaged harness gets replaced.
A meter reading of the sensor’s resistance follows, which only a technician takes.
The sensor is replaced based on that reading, or the electronic oven control is replaced if sensor and wiring are sound.
1C/7C is an internal electronic oven control error
