• Broken or damaged heating element (upper or lower element depending on model)
• Loose or corroded wire connections between sensor and control board
• Control board malfunction preventing proper temperature regulation
• Door latch switch failure preventing oven from entering operational mode
• Overheating protection triggered by excessive internal temperatures
• Power supply issues delivering insufficient voltage to heating circuits
• Moisture or debris interfering with sensor connections

Safety Checks You Can Do
• Unplug the oven from the electrical outlet for 60 seconds, then plug back in to reset the control board
• Verify the oven door is completely closed and latching securely
• Check that you have selected the correct cooking mode (Bake, Broil, etc.) before attempting operation
• Ensure nothing is blocking the oven vents or air circulation areas
• Confirm aluminum foil or cookware is not touching oven walls or heating elements
• Allow the oven to cool completely if it was recently used before attempting restart
• Verify the oven is receiving adequate power by checking wall outlet with another appliance
