Microwave blow 1 of 20 amp fuses. Replace it and test circuits before plugging in. Disconnected the mag tube and tested diode gate. Turn power on display came on set the clock. Blower fans works on all speeds. When you set the cook time it the start swich blows the same 20 amp fuse. Looks like a bad short circuit. What do you think the problem can be. I tried everything?

Hello, does it blow the fuse when the mag tube is disconnected? you will need to disconnect the high voltage side of the microwave, typically it will be a shorted mag tube that blows the fuse. That model number is not a full number, i cannot find a proper wiring diagram without the full model number.
