I replaced my ac adapter about 6 months ago and it’s getting very hot. Why?
It’s shorting out. You need to replace it. Did you get an off brand? If you tell us which machine you have we can direct you to the correct replacement. Go to this link to help identify your Mac: http://www.ifixit.com/Mac-Parts
The more the laptop gets used, the warmer the adapter may become.A relatively warm power adapter is normal, especially when the laptopis being used and the battery is being charged
