Chemical vs standard glass fuses

I have an Audiovox flat panel in the shop for repair. There is an
open 7,0 amp chemical fuse on the power supply board which I am told
may be the extent of the problem on this model. Of course it could
also be the tip of the iceberg for sure. I won't know until I replace
it. The problem is I have no chemical fuses, only glass. Can it do any
harm to replace the 7.0 amp chemical fuse with a 7.0 amp AGC type?
Chemical fuses like the 'Belfuse' series are coated with a chemical
that burns when the fuse wire reaches a set temperature. They are very
fast blow and a special class of fuse. I wouldn't recommend using a
standard fuse, since you can cause major damage in the equipment before
it blows.
What type of power supply are you working with in that unit? If it's
a linear supply, can you substitute a variable voltage, and current
limited power supply for testing?

You can't fix stupid. You can't even put a Band-Aid™ on it, because it's
Teflon coated.
