Answer Ann, It shouldn't be that hard at all, Remove the elements and drip pans, raise the front of the cooktop, support the cooktop using the support rod. unsnap the receptacle from the retainer clip and or remove the mounting screw(that could be difficult) repalce the parts and reverse the procedure. Just make sure you remove power to the cooktop before you do anything.
