Magic Chef oven displays F10, often described as runaway temperature; oven may overheat or shut down.

Safety first: If the oven is overheating, turn off the breaker immediately and allow the unit to cool completely.

• Test temperature sensor: With power off, remove and disconnect the sensor. Measure resistance at room temperature (about 1050–1100 Ω). If readings are very low or high, replace the sensor.
• Inspect wiring: Check the sensor harness for melted insulation or contact with metal chassis that could cause a short.
• Check EOC relays: With the rear panel removed, visually inspect the EOC for burnt or welded relay contacts. If the oven heats even when off, a relay is likely stuck closed.
• Replace faulty parts: Replace the oven temperature sensor if out of spec. If the sensor and wiring are good but F10 persists, replace the electronic oven control board.

When to call a technician: Any sign of severe overheating, melted wiring, or burning smell warrants professional inspection.
