Precautionary measures

• Allow the oven to cool completely (at least 30 minutes) before attempting to use it again
• Ensure the oven door is fully closed and latching completely
• Review your oven's settings to confirm no control lock feature is accidentally enabled
• Wipe down the exterior of any visible temperature sensors with a clean, dry cloth if accessible without opening the oven cavity
• Turn off power to the oven at the circuit breaker for 60 seconds, then turn back on to perform a hard reset
• Attempt to run a test cycle on a basic cooking setting to see if the error clears
• If the error code persists after these steps, contact a professional appliance repair technician or appliance repair support service to diagnose and repair the specific fault
