Possible Causes
Faulty Start button on keypad,Door not detected as closed,Child lock enabled,Control PCB relay failure
How to Fix / Troubleshooting
Safety first: Unplug before opening the control panel.
- 1. Check child lock: Many Russell Hobbs microwaves have a child lock. Look for a lock icon on the display. To clear, typically press and hold the Stop/Cancel or a specific key combination for several seconds (refer to the user manual).
- 2. Confirm door closure: Ensure the door is fully closed and latched. If the display shows a door error icon, address the door switches first.
- 3. Test other keys: If other keys respond but Start does not, the Start pad on the membrane keypad may be faulty.
- 4. Internal inspection (advanced): Remove the control panel and check the keypad ribbon cable and control PCB for damage. Replace the membrane keypad if the Start key is unresponsive.
- 5. If Start is detected but no relay click: The main power relay on the control PCB may have failed and will need professional replacement.
