Possible Causes

Failed temperature measurement circuit on main PCB, Dry solder joints on sensor input, Overheated or damaged components on control board, Incorrect sensor type fitted previously

How to Fix / Troubleshooting

Safety first: Disconnect the oven from mains before accessing the control board.

  • Confirm sensor is OK: Before blaming the PCB, test the oven temperature sensor resistance at room temperature and at a warm temperature (e.g., after heating with a hairdryer). If readings change smoothly and match specifications, the sensor is likely good.
  • Inspect PCB: Remove the top cover and carefully take out the main control PCB. Look for burnt areas, cracked solder joints around the sensor connector, or bulging capacitors.
  • Reseat connectors: Unplug and replug the sensor connector and any related harnesses to ensure good contact.
  • Board replacement: If visible damage is present or E6 persists with a known-good sensor, replace the main control PCB with the correct Russell Hobbs spare part. Transfer any configuration jumpers as per the service documentation.
  • Reassemble and test: After refitting, run the oven at several temperatures to confirm stable operation.
