My ge profile refrigerator is leaking water underneath the left side of the door periodically.
Usually every few days. Do you have an answer why?

Several things can cause this. The first thing to do is turn off refrigerator and unplug it. Then pull it out and remove the rear cover at bottom of the refrigerator. You can then wash out the coils and drain pan. Empty out the refrigerator and then on each side there are evaporator coils that have drains at the bottom. Wash out these drain pans and blow out drain tube with water like from a hose nozzle, which you will also need to wash out rear condenser coils and the condenser fan. Vacuum up water and you are done after replacing rear cover. Here is the manual: https://dl.dropbox.com/u/8010163/GE_Profile_Side_by_Side_refrig.pdf
