Does not turn on at all the outlet is fine we checked it

Check input power supply by tester if its conform its OK then check the oven control box .try to check any abnormalities there .

If you are getting your microwave to turn on then you are just fine on your outlets. They should be putting out 120v. You just have an under powered Microwave.

Open the case and check the fuse on the floor of the unit near where the power cord enters.

first check the power to the outlet.
plug something else (that works) into that outlet to see if it has power.

Is there power at the outlet? You say you checked the fuse ... is that the one inside the machine? Is the outlet protected by a GFI (reset for a GFI is on the GFI)? A GFI looks like a ordinary outlet but is very sensitive to electrical irregularities. Your circuit breaker may be on or your power panel fuse may be fine and the fuse inside your oven may be fine. If the GFI is popped, you have no power.

Try some other electrical device in the outlet. Does it work? Try an extension cord from a known hot outlet?

Beyond these tips, you may need professional help with this.

It is possible that the interconnection link(s) between the two sockets in the duplex outlet have blown apart. Turn off power at the electrical panel for this circuit, remove the outlet from it's box, and check the interlink on both sides. If obviously burned, replace the socket. A better option is to run another duplex cable from the breaker box to the outlet from a new breaker, cut the interconnections on the new socket, and wire the new cable to the isolated part of the socket. This supplies full power to each half and allows both units to run at the same time.

try another wall outlet.
