Unscrewed the cover of the microwave replaced the blown fuse with the new fuse, plugged in the microwave and tested all functions and everything worked fine. Thx for quick delivery.
First i removed the 3 phillips head screws from the back of the microwave,these hold the wrap around cover in place, then slid the wrap around cover off towards the back side of microwave, next from inside the microwave i removed 1 screw holding the front operating panel, this screw is located staight up from the push button towards the top of the microwave, I pulled the panel out enough to get the broken push button out, then i installed the new push button,then reinstalled the operating panel then the wrap around cover, very simple repair saved a lot of money by replacing the part rather than buying a new microwave.
unscrew microwave's cover,test the fuse which is located at top rear left side, the fuse is inside a plastic tube,if the fuse is burnout,just replace it.
