Proline Display Power or Backlight Failure

Digital display is blank or very dim, but the freezer still cools.

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

Failed display PCB, Burned-out LED backlight, Loose connector between main PCB and display, Low DC supply voltage from control board

Safety first: Unplug the freezer before removing the control fascia.

Steps to restore display:

1. Access display panel: Remove screws/clips holding the control fascia and gently pull it forward.
2. Check connectors: Reseat the ribbon cable or wiring harness to the display PCB.
3. Inspect for damage: Look for burned components or corrosion on the display board.
4. Replace display PCB: If the freezer cools normally but the display remains blank, install a compatible Proline display board.
