Kenmore Range Error Code 1d11

Upper oven temperature sensor resistance too high (>2237 ohms at door unlock)

Kenmore codesKenmore range codes

Upper oven temperature sensor resistance too high (>2237 ohms at door unlock) – disables all cooking functions for the cavity.

First step from the service manual

What 1d11 means on a Kenmore range

Error code 1d11 on a Kenmore range indicates that the upper oven temperature sensor is reading a resistance value above 2237 ohms at the point when the door lock mechanism disengages. The temperature sensor, also called a resistance temperature detector (RTD), is designed to read approximately 1000 ohms at room temperature (around 75°F). When the control board receives a resistance signal that exceeds the 2237-ohm threshold during a door unlock event, it interprets this as a sensor fault and disables all cooking functions for the upper oven cavity to prevent unsafe operation.

The most common root causes fall into two categories: a failed temperature sensor or a wiring problem between the sensor and the control board. A sensor that has drifted out of spec or suffered an internal break will produce abnormally high resistance readings. Similarly, corroded connectors, a pinched wire, or a broken wire in the sensor harness can add resistance to the circuit or create an open condition, both of which push the resistance reading above the fault threshold.

Diagnosing this code begins with disconnecting the sensor and measuring its resistance directly at the sensor terminals using a multimeter. A healthy sensor reads close to 1000 ohms at 75°F. A reading significantly higher than this, or an open circuit reading, confirms sensor failure. If the sensor measures correctly at its terminals, the technician should then inspect the wiring harness for damage, check connector pins for corrosion or backing out, and test resistance through the full circuit path back to the control board.

Common causes of 1d11

  1. 01

    Failed upper oven temperature sensor

    Part replacement

    The RTD sensor itself has drifted out of calibration or developed an internal open circuit, causing resistance readings well above the normal 1000-ohm baseline. Confirm by disconnecting the sensor and measuring resistance directly at its terminals with a multimeter.

  2. 02

    Broken or damaged sensor wiring harness

    Part replacement

    A wire in the sensor circuit that has been pinched by the oven door hinge, burned near the oven cavity, or stressed over time can create an open or high-resistance path. Visually inspect the harness from the sensor to the control board connector for any visible damage.

  3. 03

    Corroded or loose connector pins

    Wiring / connection

    Connectors at the sensor terminals or at the control board input can develop corrosion or allow pins to back out, adding resistance to the circuit. Inspect all connectors in the sensor circuit and clean or re-seat them as needed.

  4. 04

    Control board input fault

    Part replacement

    In less common cases, the control board's sensor input circuit may be faulty, causing it to misread an otherwise healthy sensor signal. This should only be considered after the sensor and full wiring path have tested within spec.

Frequently asked questions about 1d11

What does 1d11 mean on a Kenmore range?
Code 1d11 means the upper oven temperature sensor is reporting a resistance value above 2237 ohms at the time the door lock releases. Because the control board cannot confirm a safe, accurate temperature reading, it disables all cooking functions in the upper oven cavity. The sensor should normally read close to 1000 ohms at room temperature, so a reading this far above normal points to a sensor failure or a wiring issue.
Can I fix error code 1d11 myself?
A knowledgeable DIYer can diagnose this code with a basic multimeter by testing the sensor resistance at the sensor terminals. If the sensor reads significantly above 1000 ohms at room temperature, replacing the temperature sensor is a straightforward repair involving disconnecting the wiring connector and removing two mounting screws inside the oven cavity. If the sensor tests correctly, the wiring harness and connectors require a more thorough inspection, which may be more involved.
Is it safe to use my Kenmore range while code 1d11 is active?
The upper oven cooking functions are disabled when this code is active, so the range will not allow you to use the upper oven for baking or broiling. This is a safety protection built into the control system. Do not attempt to bypass the fault, and have the sensor or wiring repaired before resuming upper oven use.
Will resetting the range clear error code 1d11?
Resetting the range by cutting power at the breaker may temporarily clear the code display, but the fault will return as soon as the control board checks the sensor circuit again during operation. Because the code is triggered by an out-of-range hardware reading, a reset alone will not resolve the underlying sensor or wiring problem.
How much does it cost to repair a Kenmore range with error code 1d11?
If the upper oven temperature sensor is the cause, replacement sensor parts typically range from around 20 to 60 dollars depending on the specific model. If a professional technician performs the repair, total costs including labor generally fall between 100 and 250 dollars. A control board replacement, if that turns out to be necessary, would cost more and is typically diagnosed only after sensor and wiring issues have been ruled out.
