Timer and clock work, but oven shuts off before timer ends or randomly during cooking

Safety first: Turn off power before accessing wiring or controls.

• Check power connections: Inspect the terminal block and internal power wiring for loose screws or heat damage. Tighten and repair as needed.
• Control cooling: Ensure the cooling fan operates properly to prevent control board overheating.
• Inspect control board: Look for signs of heat damage or cracked solder joints on the electronic oven control board. Replace if suspect.
• Thermal devices: Test any thermal fuses or thermostats for intermittent operation (may require heating and cooling tests). Replace if unreliable.
