Oven shuts off by itself during baking on a Magic Chef oven, sometimes after 10–30 minutes, with no error code.

Safety first: Turn off power before inspecting wiring or thermostats.

• Check ventilation: Ensure the oven has proper clearance and vents are not blocked by cabinetry or foil.
• Inspect cooling fan: On models with a cooling fan, verify it runs during baking. If not, test and replace the cooling fan motor or thermostat.
• Check terminal block: Tighten all power connections and look for heat damage.
• Test high-limit thermostat: Locate the high-limit on the top or rear of the oven cavity. If it opens at too low a temperature or is weak, replace it.
• Control board: If all else checks out, the EOC may be failing under heat. Replace the electronic oven control.

When to call a technician: Intermittent shutdowns can be complex; professional diagnosis is often the quickest solution.
