Microwave Repair

hi,
my microwave is dead and i want to try to replace the fuse, but not sure which one it is - i have (tried to!?) attach a picture labeled with ‘A’ and ‘B’ if someone could tell me which one it is! also, is it safe to touch this area or any precautions i need to take?
thanks!

Locate the fuses on the parts diagram and then test for continuity using an OHM meter. Be aware that sometimes components that look like fuses (ie hood thermostat on my jvm3670) reads open and not closed like must fuses.
DO NOT Poke around inside the microwave without first discharging the capacitor or you might get seriously injured.
