How to Fix / Troubleshooting
Safety first: Disconnect the oven from mains power before removing the control panel.
- Check for life:
- Confirm whether any segments or indicators light up at all.
- If completely dead, suspect power or the display module.
- Access display:
- Remove the control fascia to expose the display PCB.
- Inspect the ribbon cable and connectors between the display and main/UI PCB.
- Reseat connectors:
- Disconnect and reconnect the ribbon cable, ensuring it is fully seated.
- Look for cracked solder joints on the display pins and re-solder if necessary (only if competent).
- Replace display module:
- If the display remains blank or corrupted, replace the complete display PCB or UI assembly with a Hoover-compatible part.
- If still faulty: The main control board may not be supplying correct voltage to the display; professional diagnosis is recommended.
