Oven shuts off by itself before the set cook time is complete; no error code displayed.

Safety first: Turn off power before accessing rear or top panels.

• Observe pattern: Note whether the oven shuts off only during high-temperature or long cycles, which suggests overheating.
• Check cooling fan: During operation, listen for the internal cooling fan. If it never runs, test and replace the cooling fan motor as needed.
• Inspect high-limit thermostat: Locate the high-limit thermostat near the oven top or control area. Test for continuity at room temperature. Replace if it opens at normal operating temperatures.
• Check power connections: Inspect the terminal block and wiring for loose or burned connections that could cause intermittent power loss.

If hardware checks are normal, the electronic oven control may be shutting down erroneously and may need replacement.
