Is this a 4 amp fuse? or even a fuse at all

[eradz]

Hey all, need some help on fuses.

I got a bad 3 amp fuse on an inverter board on another comp. I tore apart this old monitor and check the board. I think i found what could be a 4 amp fuse. In the pic the white thing has a 4 on the top. Im guessing its a 4 amp fuse? If it is, could i replace the 3 amp fuse with that 4 amp fuse?

Thanks

Here is what the board looks like:

White rectangular block with metal ends? Sounds like a fuse to me.
go at it with a DMM and see if it's blown or not.

I checked connectivity with the fuse(what i think it is) in the pic and its working fine. I just need to make sure thats a fuse and its 4 amp. Im new to this whole circuit board thing.
