First, if you have little to no experience working on a furnace or feel uncomfortable in any way working on the furnace it is critically important that you bring in a certified HVAC tech to diagnose and fix the problem. Also, without more information it is hard to provide any real idea of what could be causing the problem.

That said, there are a couple of things you can do.

First, your furnace should have an LED error.fault code display on the control board attached to the furnace. You can find the control board location on page 3 of this document: http://www.xpedio.carrier.com/idc/groups/public/documents/techlit/58dl-5pd.pdf. To find a description of how to read the codes and what they mean (though this is not specific to your furnace if it is a Carrier Base 80, but general to Carrier, because there wasn't a listing of fault codes for the Base 80 that I could find) you can go here: http://www.xpedio.carrier.com/idc/groups/public/documents/techlit/58dl-5pd.pdf.

For a list of steps you can take that may be more specific to the problem you describe, you can go here: http://www.ehow.com/how_7988383_carrier-but-wont-shut-off.html. However, the steps described on this webpage may be beyond what you feel comfortable doing or your experience level. It is far safer and better to ensure the work is done properly than cheaply.

Hope this helps.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
