Precautionary measures
• Verify the oven is receiving proper electrical power by checking that it's plugged in securely
• Confirm the circuit breaker for the oven hasn't tripped; if tripped, reset it and monitor for recurrence
• Ensure no control lock feature is activated on the control panel
• Completely close and latch the oven door, checking that it seats fully
• Allow the oven to cool for at least 30 minutes, then power cycle the unit by switching the circuit breaker off for 60 seconds, then back on
• Check that all oven settings are correctly configured for your desired cooking mode
• Inspect the oven interior for any visible debris or obstructions around the sensor area (do not attempt to clean the sensor)
• Power down the oven and wait 5 minutes before attempting to use it again
• If the error code persists after these steps, contact a professional appliance repair technician or appliance repair support service to diagnose and repair the temperature sensor issue
