Description

A direct-replacement display power control board assembly that supplies and manages the refrigerator's front display and controls for reliable user-interface operation. Restores visual display, touchpad response, and control signaling when the original board fails.

• Powers and controls the front display and backlight; commonly replaces a board causing a blank or unlit display.
• Receives touchpad inputs and sends user commands to the main control; may resolve unresponsive or intermittent buttons.
• Can be the source of UI-related error codes, flickering, or garbled readouts when the display electronics fail.
• Used when display electronics are physically damaged, moisture-exposed, or otherwise nonfunctional.

What's included: One display power control board assembly. Install notes:

• Always disconnect power to the appliance before servicing to avoid electrical shock.
• Handle the PCB by its edges and use ESD precautions (antistatic wrist strap or avoid carpeted areas).
• Re-seat all connectors and ribbon cables carefully—do not force connectors or bend pins.
