Refrigerator Display and control panel board: What It Does and Signs It's Failing

The control panel and display on the door or inside the fridge. It shows temperatures and codes, takes your settings and talks to the main board. On Samsung Family Hub models it's a large touchscreen with its own board.

How it works

On door-mounted displays the board sends your settings to the main board over a data line through the door hinge and gets temperature and status back.

Signs it is failing

• A blank or frozen display
• Buttons that don't respond
• Communication codes between the display and main board
• Family Hub screen frozen or rebooting

Communication codes can involve this board, the main board or the harness at the door hinge. A power cycle clears many of them.

Can you replace it yourself?

Cut power for a minute and restore it. Check for demo or lock mode; LG's demo mode even shuts off cooling. The board comes out with screws and plug-in connectors, but Family Hub screens are a service job.

Buying the right part

Match the color and model number exactly. Family Hub parts are pricey, so confirm warranty first.
