• Oven fails to heat or heats inconsistently
• Temperature display fluctuates or shows incorrect readings
• Cooking times are significantly longer than expected
• Oven may shut off during preheating or cooking cycles
• Error code F3 appears on the display panel
• Oven beeps continuously or intermittently
• Unable to complete preheat cycle before timeout

Possible Causes
• Faulty oven temperature sensor (RTD or thermistor) in the baking cavity
• Loose or corroded wiring connections to the temperature sensor
• Damaged sensor probe or cracked sensor housing
• Control board malfunction preventing proper sensor signal reading
• Buildup of food debris or grease around the sensor element
• Voltage fluctuations from household electrical supply affecting sensor calibration
• Defective wire harness between sensor and main control board
• Failed electronic control module unable to interpret sensor signals

Safety Checks You Can Do
• Turn off power to the oven by switching the circuit breaker to the OFF position for 60 seconds, then switch back ON to perform a complete reset
• Ensure the oven door closes completely and latches properly without gaps or resistance
• Check that the circuit breaker for the oven is in the ON position and has not tripped; reset if necessary
• Allow the oven to cool completely for at least 30 minutes before attempting to use it again
• Verify that all control panel buttons are responsive and not stuck or damaged
• Confirm that the oven is set to the correct cooking mode (Bake, Broil, or Convection) before starting
• Inspect the oven interior for visible food debris or spills near the sensor location on the oven wall and clean carefully if accessible
• Attempt to run a preheat cycle again and monitor if the error code reappears within 5 minutes
