Common Symptoms
- Blank or nonfunctioning refrigerator display.
- Temperature settings are not displayed or cannot be adjusted at the display.
- Dispenser settings are not displayed or cannot be adjusted at the display.
Check Before Replacing
- Confirm the refrigerator has power, then observe whether the display can show and change its temperature and dispenser settings; these symptoms alone do not prove the board has failed.
- Verify the refrigerator's complete model number and the installed part number before ordering, because similar-looking display components can differ by model.
- With the refrigerator unplugged, visually inspect the accessible display-area connector and wiring for an obviously loose connection or visible damage before condemning the board.
Pro Tip
This is the display PCB only: the service parts listing identifies the display case and display cover as separate parts, so a cracked housing or cover is not corrected by replacing this board alone.
