It's an integral fridge, so I doubt it has been moved...
However, now is the time to move it
Just pull it out and check the plug is in the socket properly - cats... - if it is, take it out, change the fuse [google is your friend if you're struggling here], if it still doesn't work buy a new one - Hell you keep telling us how much you earn in commission / bonus, so a couple of hundred quid shouldn't hurt much
