Possible Causes

Weak internal power supply on control PCB, Loose display connector, Failing display module, Overheated control board

How to Fix / Troubleshooting

Safety first: Disconnect mains power before accessing the control area.

Steps to check:

  • Ventilation: Ensure the oven's top vents are not blocked, as overheating can affect the control board.
  • Connector check: Remove the control panel and reseat the ribbon cable between the display module and main PCB.
  • Visual inspection: Look for bulging capacitors or burnt components on the control board. If present, the board should be replaced.

Important: Because this involves low-voltage electronics, replacement of the complete Tower control PCB or display module is usually more practical than component repair for home users.
