A Samsung NE63T8751 whose display is blank, whose keys do not respond or whose controls behave strangely has a few quick tests to run, and one of them is particular to the Flex Duo design. This electric range has a radiant smoothtop, a Flex Duo oven with a removable Smart Divider, Air Fry and SmartThings Wi-Fi. Its control panel handles the cooktop, the oven and the Flex Duo zones, so a display problem can look bigger than it is.
The checks in more detail
Start with the glass and the lock. Wipe the panel with a soft, slightly damp cloth and dry it, because moisture, grease and steam make a touch panel misread or ignore touches. Look for a lock indicator: Samsung ranges have a Control Lock, turned on or off by holding the Lock key for about three seconds, which disables the keys. A locked panel looks dead but is not.
If a key seems to beep without response, check that a pot or cloth is not resting on the panel. Then think about Flex Duo. If you installed the Smart Divider, the display shows the zones and the controls ask you to choose upper, lower or both; a panel that seems to ignore a temperature entry may be waiting for you to choose a zone. Check whether the divider is seated and whether Flex Duo mode is on.
When the display is frozen, reset by switching off at the breaker for a minute and restoring power, which clears a software hang. If the display is blank, check the range's double breaker, since a range depends on its supply; the cooktop elements and the oven are dead together if the breaker has tripped. If the panel is dark with power on, or characters are garbled, the display or the control board may have failed, and Samsung service can diagnose it with NE63T8751SS and the serial number.
