My Microwave Display Is Blank.

If your microwave has power but the display is blank, it has entered energy-saving mode features called Auto Sleep.

Note:

To help conserve energy and comply with the U.S. Department of Energy (DOE) Energy Conservation Standards for Microwave Ovens, microwave ovens manufactured on or after June 22, 2026 may automatically enter a low-power mode when they are not in use.

To conserve energy, the screen automatically turns off after 2 minutes of inactivity. This is a normal energy-saving feature and does not affect microwave performance.

• Verify the microwave is plugged into a working electrical outlet.
• Press any button on the control panel. You can also press the Door release button.
• The display should immediately turn back on.
• Continue using the microwave as normal.

If the display does not illuminate after pressing a button, verify the outlet has power. If the microwave still does not respond, refer to your Owner's Manual or contact Panasonic Customer Support.
