How to Fix / Troubleshooting
Safety: Unplug the microwave before accessing the control panel.
- Power reset: Unplug for 5 minutes and plug back in. Sometimes a reset can restore a flickering display.
- Inspect connections: Remove the control panel and check the connectors between the display module and control board. Reseat any loose plugs.
- Replace display/control board: If the display remains dim or blank, replace the display module or the entire control board assembly, depending on your Kenmore model design.
The microwave may still function with a dim display, but usability is reduced. Replacement is the long-term fix.
