What 1d22 means on a Kenmore range

Error code 1d22 on a Kenmore range indicates that the lower oven temperature sensor (also called an RTD sensor or oven probe) is reading a resistance value above 2787 ohms at the point when the door lock engages. This threshold is evaluated during the self-clean cycle initiation or other door-lock sequences, and if the sensor resistance exceeds this limit, the control board interprets the reading as an out-of-range fault. As a safety and accuracy measure, the control disables all cooking functions for the lower oven cavity until the fault is resolved.

The temperature sensor in a Kenmore range is a resistive probe, typically a platinum RTD, whose resistance changes predictably with temperature. At normal room temperature, a properly functioning sensor reads within a specific resistance range. A reading above 2787 ohms indicates the sensor is either failing open, has degraded internally, or the circuit between the sensor and the control board is compromised. Common circuit issues include corroded connectors, pinched wiring, or a broken wire in the sensor harness.

Diagnosing this fault begins with disconnecting the sensor from its wiring harness and measuring resistance directly across the sensor terminals with a multimeter. If the reading exceeds the specified threshold or reads open (OL), the sensor itself has failed and requires replacement. If the sensor reads correctly in isolation, the wiring harness and connectors between the sensor and the control board should be inspected carefully for damage, corrosion, or continuity breaks.

Common causes of 1d22

  1. 01

    Failed lower oven temperature sensor

    Part replacement

    The RTD temperature sensor itself has degraded or broken open, causing resistance to exceed 2787 ohms. Confirm this by disconnecting the sensor and measuring resistance directly across its two terminals with a multimeter.

  2. 02

    Damaged or broken sensor wiring harness

    Part replacement

    The wires connecting the temperature sensor to the control board may be pinched, burned near the oven cavity, or broken internally. Inspect the full length of the harness for visible damage and test continuity on each wire.

  3. 03

    Corroded or loose sensor connector

    Wiring / connection

    The connector at the sensor or at the control board end can corrode or back out over time, increasing circuit resistance. Disconnect both ends of the harness, inspect the terminals for corrosion or spread pins, and reseat all connections firmly.

  4. 04

    Control board fault

    Part replacement

    If the sensor and wiring both test correctly, the control board input circuit for the lower oven sensor may have failed, causing an incorrect resistance reading. This is less common but should be considered after ruling out the sensor and harness.

Frequently asked questions about 1d22

What does 1d22 mean on a Kenmore range?
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.
Can I fix error code 1d22 myself?
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.
Is it safe to use my Kenmore range while error code 1d22 is active?
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.
How much does it cost to repair error code 1d22 on a Kenmore range?
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.
Will resetting the Kenmore range clear error code 1d22?
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.
