Oven displays a generic fault code and beeps; no specific subsystem indicated.

Safety first: Disconnect power before opening any panels. Do not bypass safety devices.

• 1. Note conditions: Record what mode was active when the error occurred (bake, grill, self‑clean, etc.). This can help narrow down the subsystem involved.
• 2. Power reset: Turn off the breaker for 10–15 minutes to fully discharge the control. Restore power and test basic functions one at a time.
• 3. Check visible components: Remove the rear and top panels and inspect for burnt wiring, damaged connectors, or obvious component failures (e.g., charred relays).
• 4. Test major sensors: Verify continuity of the oven temperature sensor, door lock switches, and thermal cut‑outs. Replace any failed components.
• 5. Replace control board: If all peripherals test good and the generic fault persists, the main control board is likely defective and should be replaced by a qualified technician.
