[Boatanchors] OT: Fuse replacement?

[n griggs]

Check to make sure the door switches are functioning.  I repaired three that had blown fuses (and got 3 good microwaves in the process) because the door switch that shorts the secondary of the transformer never opened when the door was shut.  This is a safety feature to make sure that the magnetron is never on when the door is open AND to stop any excess oscillations of the tube!  Usually the switch is across the high voltage winding but I did have one across the filter cap.

Warning - this is OT!

I am repairing a circuit board from an oven (one of these high tech
thingies). The company wants $400 to replace the board. But it looks like
only 1 fuse blew. Yes, it might have blown for good reasons, but I thought
Id first just try to replace it. It is soldered onto the board. These are
the markings on it:

250V   6/10A

Could this mean that for 250V it will blow at 6A but at 125V it will blow at
10A? (ie blows at 1,250W?)

The only replacement I could find in mouser says this:

125V   6A

Does this sound like a replacement? Could it be under rated? I don't mind it
being a little underrated, I would just rather not put in something
overrated.  
Thoughts?
