I have been told the smart board in my GE JMV1440 microwave. How hard is it to replace myself. I work in computers so I have an electronics backround.
To replace the smart board in your microwave, you would first need to remove the vent grill at the top of the unit by removing a couple of screws on the top. Once removed there would be 1 screw holding the control panel in place. Remove the screw and lift and pull out of the control panel which will give you access to replace the smart board. Make sure power is disconnected when doing this.
