I have a Frigidaire side by side Refrigerator and it has frozen water in the bottom of the freezer. If it is not daily removed water will leaking onto the floor. I do not have the ice maker connected. Can this be repaired or will I have to call a professional?

Most likely the defrost heater is bad and the ice builds up. If you are so inclined, remove the bottom tray of the freezer, chip out the ice-carefully-, You should see a round thick wire looking strip under the freezer tray, remove the heater strip and replace. It could also be the defrost timer but it is usually the defrost strip.
