Blown fuse to HV transformer.

I've repaired plenty of these,where in the UK are you?I'm at the
Borders near Holy Island.If it's tripped whilst cooking and you are
fully up to date with microwaves I'll walk you through the repair.You
shouldn't have opened it and tested if you did not discharge th hv.
don't assume door switches are ok,replace them as they are dirt
cheap,it's possible the thermal cutouts at that control the oven/mag
have failed.They are small round discs with the operating temp.on
them.Replace them they are cheap.You need the standard 8A microwave
fuse to replace,buy them in packs of ten for a quid.
I won't put insructions on the group but if you don't get there you
can e-mail me and I'll help you.Frank@Teletronic Services[UK]

Why not? That what this group is for.

So how would a bad door switch or thermal cutout blow only the fuse in-line
to the HV transformer? A bad door switch could blow the main fuse.
A bad thermal cutout could stop it from heating.
