Rafael, Welcome to the DIY Forums.
Yes, settling can cause cracks. If they are just around the outside of the fireplace you could use mortar to repair them. If they are inside the fireplace then a firebrick mortar would have to be used. If that is the case, I would get a Pro to do it. There are certain things that have to be done and you don't want to take the chance of doing it wrong and burning your house down. Good luck.
P.S. Look up in the chimney to check for interior cracks.

Thanks for the reply. I think this forum is great and I have alot of
questions to ask . Can we add a photo if so how. Thanks again.
