Bosch microwave.

I dont generally touch microwaves but this is my own integrated one. Model no is HMT85M650B/02. Checked 10a fuse and it was gone. replaced and blew on start. tripped mcb and not rcd. Any ideas.

find the inverter
item 420

disconnect the 2 supply wires to the inverter

go armed with smaller fuses. i use 6.3A just to test

the 2 things that can blow fuses are
1 door switches
2 failed inverter

if you disconnect the 2 pin mains plug to the inverter then it shoulld turn on and start with no problems. the programme will abort as soon as it cant see the inverter but if it does all this with no fuses going you need a new inverter plus maybe a new Mag. All of which is cheaper to source as panasonic parts
