Precautionary measures
• Verify the oven is properly plugged into the wall outlet and power cord is fully inserted
• Check your home's circuit breaker panel—locate the breaker serving the oven and confirm it is in the ON position; if tripped, flip it OFF then back ON
• Ensure the oven door is completely closed and latched properly
• Look for any visible control lock feature on the display panel and disable it if activated
• Allow the oven to cool completely for at least 30 minutes before attempting to use it again
• Perform a complete power reset by switching off the circuit breaker for the oven for 60 seconds, then switch it back ON
• Wait 2-3 minutes for the oven to fully reinitialize and check if the error clears
• Attempt to start a cooking cycle to see if error code F1 reappears
• If the F1 error code persists after these steps, contact a professional appliance repair technician or appliance repair support service to diagnose the temperature sensor and control board
