Mario, I have uploaded the Carrier Air Conditioner Service Manual under the "Files" button located in the blue border under the forum header. Click on this "File" button and go to Appliances section for the pdf file for the manual. page 2-4 has a chart of error code light blinks that may help you diagnose the problem. Count the blinks and pauses to look up on chart. Good luck and keep us posted.
