    Have 7300 X4 carrier refer unit. Just noticed that refer is running but there is nothing on the screen. Like it is off. What that can be? And what should I do to fix it?
    Thank you.

    You might open the side door and reach in and make sure everything is plugged in good leading too the panel. Can you see anything (text) as in maybe it’s just the backlight?

    Carrier has a optional sleep mode for the screen.
    If you know how to access the technician mode on the keypad you can change that.
