Microwave burned the fast fuse and 'rectifier' 2x062 on this schematic

Replaced it with hvr 6x2 diode however once again it and fuse burned
though "high voltage rectifier" diode hvr1x stayed ok
(hvr 6x2 short, hvr 1x conducting 0.25 ma when tested with 4.5v)
Magnetron ok, so what could be the reason for this-perhaps capacitor
or some contact with oven interior along points A or B?
thanks in advance
