One element on my KitchenAid

Sure can. One element can easily be replaced. If your model number is correct, you can find replacement parts at searspartsdirect.com. Type in your model number in the Search menu and the surface elements can be found under the "Cooktop Parts" heading. I do not know which element you have that is bad, but they are identified as item 12 and by wattage rating. Use care when selecting to make sure you identify the correct element. The smaller elements have a lower wattage rating than the larger elements. There's also an illustrated view for easy part identification. Some parts come with directions on how to replace. If no instructions are available, or if you need further guidance, go to my profile page and click on "Tips and Tricks. I have a write up listed there on how to replace a glass cooktop. Those same instructions can be used to replace a single element. Instead of removing all the elements and cooktop, you will only have to remove and replace the one element. Just make sure you unplug the range before starting and handle the elements with extreme caution. They are considered fragile. It may also help to have a second person assist. I hope this answers some of your questions. If you need further assistance, please post back and let me know.
