If your microwave keypad is unresponsive or some buttons aren’t working, you may need a new switch membrane (DE34-00304L). This genuine Samsung part is designed for 1.6 cu. ft. over-the-range microwaves. Keypads can wear out over time, resulting in functionality loss. Use this replacement to restore your microwave’s usability. Exercise caution and refer to the owner's manual during installation. Verify your microwave's model number for compatibility before purchasing.
