Bosch HEI8056U 800 Series 30 in Electric Slide-In Range E011 Error Fix: Oven Temperature Sensor Open

Error code E011 on the Bosch HEI8056U 800 Series 30 in Electric Slide-In Range means: Oven Temperature Sensor Open. The oven cavity temperature sensor (RTD / NTC thermistor) has an open circuit. The control board cannot read the oven temperature. Check the sensor wire harness for breaks, loose connections, or damage from heat. Measure the sensor resistance — most Bosch oven sensors read approximately 1,000-1,100 ohms at room temperature (for RTD type). An infinite reading (open circuit) confirms the sensor or its wiring has failed. The sensor probe is typically mounted to the rear wall of the oven cavity.
