Oven shuts off by itself during cooking and may restart after cooling.

Safety first: Turn off power and allow the oven to cool completely before inspection.

• Check ventilation: Ensure there is adequate clearance around the range and that rear/top vents are not blocked by cabinetry or items.
• Inspect cooling fan: Listen for the cooling fan when the oven is hot. If it does not run, access the fan from the rear and test for continuity and free movement.
• Clean vents: Remove dust and grease buildup from vents and fan intake using a vacuum and soft brush.
• High-limit thermostat: Some models use a resettable thermal cutoff. A technician can test and replace this if it is tripping prematurely.

When to call a technician: Repeated thermal shutdowns indicate a serious issue with cooling or control components and should be professionally diagnosed.
