The ME90H1780R is a over-the-range convection microwave, listed by Samsung as Bespoke Over the Range Microwave Air Fry Max Convection | Auto Connectivity. The -SE- keypad problem is the classic complaint on an over-the-range Samsung like the ME90H1780R: steam and grease from the cooktop below reach the membrane behind the keypad, and the control reads a key as held down.
Samsung’s microwave codes on the ME90H1780R share their C- numbering with its ranges but not their meanings – C-10 to C-12 here are the gas sensor, C-20 to C-22 the temperature sensor, C-d0 to C-d2 the door or a key, C-F0 to C-F2 communication – and Samsung’s first instruction for all of them is the same: power off for a minute, let a wet panel dry, then call if the code returns.
