Possible Causes
• Faulty temperature sensor (RTD or thermocouple) in heating chamber
• Broken or disconnected heating element wiring
• Damaged upper or lower heating element
• Control board circuit board failure or sensor signal error
• Poor electrical connection between sensor and control module
• Thermal fuse activation due to oven overheating
• Corroded or loose terminal connections in the heating circuit
• Defective relay or contactor on control board preventing element activation
✅
Safety Checks You Can Do
• Unplug the oven from the wall outlet for 60 seconds, then plug it back in to reset the control board
• Verify the oven door is fully closed and latches securely with no gaps
• Check that you have selected the correct cooking mode (Bake, Broil, Convection, etc.) before attempting to heat
• Allow the oven to cool completely for at least 2 hours if overheating may have occurred
• Confirm the circuit breaker for the oven has not tripped in your home's electrical panel
• Ensure nothing is blocking the oven vents on the sides or back of the unit
• Avoid using aluminum foil on the oven bottom, as this can block airflow and trigger sensors
• Check that the oven is properly plugged in and receiving power to the display
• Wait 5 minutes after unplugging before turning the oven back on to ensure a full system reset
