Error code3d/22
ApplianceRange
Of the four 3d pairs printed for the Kenmore 665 model freestanding range, 3d/22 is the last: 3d/11, 3d/12 and 3d/21 say the same thing, that the oven temperature sensor is defective.
Handling it the way the manual does
Pull the plug or take power off the range.
Examine the sensor harness. Loose wires go back on; a damaged harness is exchanged.
Sensor resistance gets measured by a technician with a volt/ohm meter, and a reading outside the manual’s figure means a new sensor.
If the sensor and its connections are fine, the electronic oven control is the part replaced.
Booking starts with (415) 825-6393, whether you live in San Francisco or a nearby bay city. Mention that 3d/22 is showing, give the range model number and say what you did to the harness. The Kenmore range repair page gives more background.
Model compatibility: Kenmore reuses codes across series and model years, so 3d/22 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

The oven temperature sensor is defective.
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.
