Bonnie O Bismarck , ND June 09, 2019 Appliance: Samsung Microwave SMH9187B/XAA Samsung Microwave Smh9187b/Xaa: 5E or SE error code. How to replace Microwave Grease Filter. Very simple job! Gained access to old panel/motherboard, tilted out old panel/motherboard and disconnected all wires from microwave to motherboard, removed old panel/motherboard, disconnected motherboard from old panel, and then reversed steps starting by connecting motherboard to new panel, and so on.
