Grundig Display Module / Control PCB Fault

Microwave display is dim, flickering, or some segments are missing, but the unit still heats.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aging LED/LCD display, Loose display connector, Failing display driver on control PCB, Voltage drop in low-voltage supply

Safety first: Unplug the microwave before accessing the control panel.

Step-by-step checks:

1. Check for moisture: Wipe the control panel and ensure no condensation is present.
2. Access control panel: Remove the panel and inspect the display connector. Reseat it firmly.
3. Inspect PCB: Look for cracked solder joints around the display and voltage regulator components.

If reseating connectors does not improve the display, the display module or entire control PCB may need replacement.
