Replaced diode in Samsung microwave that quit heating (only 3 yrs old). Can’t believe how easy it was. Literally bought another microwave because I thought it would be too hard/too expensive to repair. New microwave handle did not match the rest of the Samsung appliances and could not be swapped out (way to go Samsung). So I thought, what the heck, let’s try. So glad I did! Hardest part was taking it off the wall to take off the million screws holding the “skin” of the unit (again, way to go Samsung). Anyway, easy and best of all CHEAP repair. Thank you!!!
