Possible Causes

Defective power supply section on main control board, Voltage fluctuations or incorrect mains connection, Loose mains terminal block, Internal fuse or varistor damage on control board

How to Fix / Troubleshooting

Safety: Always isolate the oven from mains power before opening any covers. High voltages are present.

  • Check mains supply: Verify that the oven is connected to the correct voltage (e.g. 230 V) and phase configuration as specified on the rating plate. Ensure the circuit breaker is correctly rated.
  • Inspect terminal block: Remove the rear cover to access the mains terminal block. Check for loose screws, discoloured insulation, or burnt smell. Tighten connections if slightly loose.
  • Power reset: Turn off the breaker for 10 minutes, then restore power and test.
  • Internal inspection: With power OFF, inspect the main control board for blown fuses, cracked solder joints, or burnt components in the power supply area.

Important: Component-level repair of the power supply is not recommended for untrained persons. If E007 persists after verifying the supply and connections, the main control board should be replaced by a professional.
