Display shows error and oven shuts down shortly after starting, often related to overheating

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

• Check ventilation: Ensure that the oven has proper clearance in the cabinet and that front and rear vents are not blocked by panels or insulation.
• Inspect cooling fan: Remove the top cover and verify that the tangential cooling fan runs when the oven is heating. If not, test and replace the fan as needed.
• Locate thermal cut-out: Find the safety thermostat (usually mounted on the top of the oven cavity or rear panel). Some are manual reset types with a small button; press gently to reset if tripped.
• Test thermostat: Disconnect the thermostat and check continuity. An open circuit at room temperature indicates a failed device that must be replaced.
• Check wiring and insulation: Look for misplaced insulation blocking airflow or touching hot components. Correct any installation issues.
• Replace faulty parts: Install a new thermal cut-out or cooling fan if defective. Reassemble and test the oven at a moderate temperature while monitoring for proper cooling.
