Question about LG LRM1230W Microwave Oven
Ovens working condition but not heat&blown fuse when start button is on,pls solution to me
If the fuse is blowing when the door is opened or closed, then it's likely to be a door switch. You would have to replace the defective switch and the monitor/short switch. On inverter ovens, it is also recommended that you replace the power relay.
If it's blowing after the oven starts running, then it's probably a failure of some high voltage component in the magnetron circuit.

I am not an expert on Miocrowave ovens, but from past experience I know that they have a number of micro-switches on the door as safety devices. If these switches are faulty, the last safety feature is to short the supply and blow the fuse to stop the microwave from operating in an unsafe condition. Obviously the switches would have to be checked first before jumping to any conclusions and a number of other faults would probably cause the fuse to blow as well.
