I would need to know at least the brand of furnace in order to help interpret the error code. One thing you can try is looking for a sticker attached to the furnace (probably on the inside of the cabinet) that lists the diagnostic codes. Your owner's manual should have this too. If you don't have the manual it is easy to find manuals for some brands, though there are some brands that do not offer their manuals online.
