Possible Causes

Blown internal fuse on control PCB, No mains supply at terminal block, Loose or burnt mains connections, Failed main control PCB power supply section

How to Fix / Troubleshooting

Safety first: Ensure the oven is isolated before opening any covers.

  • Check household supply: Verify the cooker switch is on and the circuit breaker has not tripped. Test the outlet with another appliance if possible.
  • Inspect terminal block: Access the rear terminal block and confirm live, neutral, and earth wires are secure and not burnt.
  • Internal fuse: Some Russell Hobbs ovens have an internal fuse on or near the control PCB. Check and replace with the exact same rating if blown. If it blows again, there is an underlying fault.
  • PCB failure: If supply and fuse are good but the oven remains dead, the main control PCB is likely faulty and should be replaced.
