Kenmore Range Error Code 3d22

Error code 3d22 means the control board has detected that the lower oven temperature sensor is reading a resistance below 15 ohms, which indicates a shorted sensor circuit. This is far below the normal resistance range for an oven temperature sensor. As a result, the control board disables all cooking functions for the lower oven cavity until the fault is resolved.

The lower oven cooking functions are disabled by the control board when this code is active, which means the range prevents you from operating the lower oven in this state. You should not attempt to bypass or reset around this lockout, as the oven has no reliable temperature control without a functioning sensor. Surface burners on gas or electric models may still function, but the lower oven should not be used until the sensor fault is corrected.

Resetting the range by cycling power at the breaker or unplugging it may temporarily clear the code from the display, but the error will return as soon as the control board reads the sensor circuit again and detects the low resistance. Because 3d22 reflects an actual electrical fault in the sensor or its wiring, the underlying problem must be physically repaired before the code will stay cleared.

A knowledgeable DIYer can often resolve this by inspecting the oven temperature sensor and its wiring harness for visible damage, then using a multimeter to measure sensor resistance at the sensor terminals. If the sensor reads below 15 ohms at room temperature, replacing the sensor is a straightforward repair involving removing a few screws and a wiring connector. However, if the wiring or the control board is involved, the diagnosis becomes more complex and a technician may be warranted.

If the oven temperature sensor is the cause, sensor replacement parts typically cost in the range of $20 to $65 depending on the specific model, and the repair is relatively simple. If wiring harness repairs or a control board replacement are needed, total repair costs including parts and labor can range from $150 to $400 or more. Getting a diagnosis before ordering parts helps avoid unnecessary expenses.
