Kenmore Range Error Code 1d22

Error code 1d22 means the lower oven temperature sensor is reading a resistance value above 2787 ohms at the time the door lock activates. This is outside the acceptable operating range, so the control board disables all cooking functions for the lower oven cavity. The fault points to a failed temperature sensor, damaged wiring, or a connection problem in the sensor circuit.

The range disables lower oven cooking functions when this code is active, so the lower oven cavity will not operate. Surface burners or an upper oven, if your model has one, may still function depending on the specific model. It is not recommended to attempt to bypass the fault, as the temperature sensor is a critical safety component that prevents the oven from overheating.

Resetting the range by cutting power at the circuit breaker for several minutes may temporarily clear the error code from the display, but the fault will return as soon as the control board re-evaluates the sensor circuit. Because the code is triggered by an actual out-of-range resistance reading, clearing the display does not address the underlying problem. The sensor, wiring, or connectors must be inspected and repaired for the code to clear permanently.

A knowledgeable DIYer can diagnose this fault by using a multimeter to check the resistance across the lower oven temperature sensor terminals after disconnecting the harness. If the sensor reads above 2787 ohms or shows an open circuit, replacing the sensor is a straightforward repair that typically involves removing a couple of screws inside the oven cavity. If the sensor tests correctly, tracing the wiring harness for damage or connector corrosion is the next step, which is also manageable without specialized tools.

If the issue is a failed temperature sensor, the part itself typically costs between $20 and $60 depending on the model, and a professional repair including labor can range from $100 to $200. If the fault lies in the wiring harness or connectors, repair costs may be lower since parts are inexpensive. A control board replacement, if required, is the most expensive scenario and can range from $150 to $350 or more for parts and labor combined.
