Maytag Range Error Code 3d11

Error code 3d11 indicates the control board has detected an open circuit condition in the upper or single oven cavity temperature sensor. The sensor's resistance reads as infinite ohms, which means the circuit is broken somewhere between the sensor itself and the control board. This is a hard fault: the board cannot receive any temperature data from the oven cavity, so it cannot regulate heat accurately or safely.

For homeowners, the oven temperature sensor is a small probe mounted inside the oven cavity, usually at the back wall. It sends resistance readings to the control board so the board knows how hot the oven is. When the sensor circuit reads infinite resistance, it means the signal is completely lost. This can happen because the sensor itself has failed internally, the wiring connecting it to the control board has broken or come loose, or a connector has corroded or pulled apart. The range displays 3d11 to let you know it has stopped trusting the temperature reading entirely.

This code will typically prevent the oven from operating, or cause it to shut down mid-cycle, because running without valid temperature feedback creates a burn or fire risk. The cooktop burners may still function normally depending on your model. Testing the sensor with a multimeter is the correct first step before ordering any parts.
