I have a General Electric side by side refriegrator (Profile) with an ice maker that is leaking water at the bottom of the door on the ice maker side. Does anyone know what causes this problem

Is the icemaker level? Is the water valve working properly? i.e. is the water valve shutting off completely? YOu could test water valve bu shutting off the water supply and drying up the water that is now present and see if problem is corrected.
