Step 03
Safety Checks You Can Do
• Turn off the circuit breaker supplying power to the oven for 60 seconds, then turn it back on to reset the appliance
• Verify the oven door is fully closed and latches properly
• Check that your home's main circuit breaker has not tripped
• Ensure the kitchen area around the oven has proper ventilation and is not too hot
• Allow the oven to cool completely for at least 30 minutes before attempting to use it again
• Open the oven door and visually inspect the interior for any debris, food particles, or obstructions around the oven cavity
• Review your oven's control panel settings to ensure you have selected the correct cooking mode
• Avoid using the self-cleaning function until the error is resolved
• Do not attempt to access or clean the temperature sensor yourself, as this requires professional service
