Causes Of Error Code E011
The E011 error code often signals a problem with the oven’s temperature sensor. This sensor might not work properly due to dirt, damage, or age. A faulty sensor sends wrong signals, causing the oven to stop working correctly.
Wiring issues also cause the E011 error. Loose or broken wires can stop the sensor from sending signals. Wires might get worn out or disconnected during repair or moving the oven. Checking wiring connections is important to fix this error.
Common triggers include:
- Dirty or damaged temperature sensor
- Loose wiring connections
- Broken or worn wires

Basic Troubleshooting Steps
Power Cycle the Oven: Unplug the oven from the power source. Wait for about 1 minute. Plug it back in to reset the system. This can clear temporary errors.
Check Door Closure: Ensure the oven door is fully closed. A slightly open door can trigger error codes. Clean any dirt or debris from the door seals to help it close properly.
Reset Error Code: After power cycling and checking the door, press the reset button if available. This clears the error code. If the code returns, further inspection may be needed.
Inspecting And Replacing The Temperature Sensor
The temperature sensor is usually inside the oven cavity. It looks like a small metal probe. It sits near the back wall or ceiling of the oven.
To test the sensor, first unplug the oven. Use a multimeter to check resistance. A good sensor shows about 1100 ohms at room temperature. If the reading is very high or low, the sensor is faulty.
Replacing the sensor is easy. Unscrew the old sensor from the oven wall. Disconnect its wires carefully. Attach the new sensor wires to the same connectors. Screw the new sensor in place. Plug the oven back in and check if the error clears.

Preventive Maintenance Tips
