Jenn Air Electric 4 Burner 30 Glass Cooktop JEC8430ADB. This unit was pulled from a high-end kitchen remodel and was functioning properly prior to removal. No other testing has been done. THERE ARE (2) SMALL CHIPS ALONG THE BORDER OF THE COOKTOP GLASS (see photos). There are also some scratches on the surface of the cooktop that are difficult to see in the photos. This is a used item so please expect normal wear (Scrapes, Scratches and Scuffs). Please zoom in to all pictures and examine closely. Feel free to reach out if you have any questions or would like additional pictures. Have a great day! What you see is EXACTLY what you get, nothing more or less. Any testing that has been done will begin listed in the description.
