Replace microwave coil
If your microwave is totally dead, it may be the line-fuse that is the problem. Leave the microwave unplugged for a day (it may contain a capacitor that could have residual electricity that could give you a nasty jolt). Undo the screws that hold the front outgoing-vent grill.
You may be able to see the fuse through the secondary grill (they don't want you touching the circuit-board, but you may have to). The line-fuse may be attached to the circuit-board.
If it is, undo the secondary grill screws, and bend the tabs that hold the secondary grill to remove the secondary grill.
Pull-out the fuse from the fuse-holder, and get an ohm-meter to test. If the ohm-meter reads near-infinite ohms across the fuse, get a magnifier to read what is on the end of the fuse.
The imprint on the old fuse should mention a rated voltage, and amperage.
Then go to Radio Shack, and buy an equivalent replacement fuse.
Replace the line-fuse with a new one, plug the microwave back in, and see if the display comes-alive, and if it does, set the clock ad try to heat a cup of water. If the cup of water heats, replace the secondary-grill (careful, that capacitor is now in-play) and screws, replace the outlet-vent-grill and screws -- you may not even have to take the microwave off of the wall !
